how is g related to the slope of the t 2 vs l graph? is the slope equal to ""g""? explain.

Answer: 12

Explanation:

The resultant vector is  12 unit.

When two vectors point in the same direction, their sum is equal to the total of their respective magnitudes pointing in the same direction.

When two vectors are pointed in opposite directions, the resultant vector is pointed in the direction of the larger vector and is equal to the difference between their magnitudes.

Here, one vector of 15 unit is acting to the left and another vector of 3 unit acting rightwards. As they are acting in opposite direction, vector summation of two vector will be equal to the value of subs traction of their magnitude.

So, Resultant vector= 15 unit + (-3 unit)

= 15 unit - 3 unit

= 12 unit.

Hence, the resultant vector will be 12 unit.

True. The step of a flywheel is the surface that the pressure plate of the clutch contacts, and it is an important factor in the function of the clutch.

The step provides a flat and even surface for the pressure plate to push against, which allows it to develop the necessary clamping force to keep the clutch from slipping.

If the step of the flywheel is not deep enough, the pressure plate may not be able to develop enough clamping force to keep the clutch from slipping. This can result in poor performance, increased wear on the clutch, and potential damage to other components of the transmission. Therefore, it is important to ensure that the step of the flywheel is within the manufacturer's specifications during installation or replacement of the clutch.

The statement is true. The step depth of a flywheel is crucial in a clutch system as it impacts the amount of clamping force the pressure plate can exert to prevent the clutch from slipping, affecting power transmission and potentially causing damage.

The statement 'If the step of a flywheel is not deep enough, the pressure plate will not develop enough clamping force to keep the clutch from slipping.' is indeed True.

In automotive engineering, the depth of the 'step' on the back of the flywheel is critically important for the operation of the clutch. The step is the recessed area where the plate fits. If it's not deep enough, the pressure plate can't exert enough pressure on the clutch disc to keep it from slipping when the engine's power is transmitted through the clutch. This may cause a loss of power to the wheels, excessive wear, and potential damage to other clutch components.

to find the modulus of elasticity MoE at 23% of moisture content based on the already given modulus of elasticity of 12% moisture content we need to consider a shrinkage behavior of material. the expected MoE comes out to be approximately \(6,836 N/mm².\)

given information:

Modulus of elasticity at 12% moisture content =7,920 N/mm²

resultant shrinkage or final shrinkage percentage FSP = 30%

To calculate the expected MoE at 23% moisture content we have the following equation:

MoE-23% =   \(MoE-12%\) \((1 - FSP (23 - 12) / (100 - 12))\)

MoE-23% = \(7,920 N/mm² × (1 - 0.30 × (23 - 12) / (100 - 12))\)

MoE-23% =\(7,920 N/mm² × (1 - 0.30 × 11 / 88)\)

MoE-23% = \(7,920 N/mm² × (1 - 0.1364)\)

MoE-23% = \(7,920 N/mm² × 0.8636\)

MoE-23% =  \(6,836 N/mm²\)

therefore the expected modulus of elasticity at 23% moisture content comes out to be approx \(6,836 N/mm²\).

people who express being madly in love are likely to report feeling intense emotions such as euphoria, happiness, excitement, and a strong desire for closeness. However, it's essential to recognize that the experience of love is complex and involves multiple neurochemical processes.

Because of the release of the neurotransmitter dopamine, people who express that they are madly in love are likely to report feeling a range of intense emotions. Dopamine is associated with feelings of pleasure, reward, and motivation, and its release in the brain can contribute to the euphoric sensations commonly experienced in the early stages of romantic love.

Individuals who are madly in love often describe feeling a sense of exhilaration, happiness, and an overall heightened state of well-being. They may experience increased energy levels, a sense of excitement and anticipation, and a general feeling of being "on top of the world." Additionally, the release of dopamine can enhance feelings of attraction and attachment, leading to an intense desire to be close to the person they love.

However, it is important to note that while dopamine plays a significant role in the initial stages of romantic love, long-term love and attachment involve other neurotransmitters and hormones, such as oxytocin and vasopressin. These chemicals contribute to feelings of trust, bonding, and long-term commitment.

In conclusion, people who express being madly in love are likely to report feeling intense emotions such as euphoria, happiness, excitement, and a strong desire for closeness. However, it's essential to recognize that the experience of love is complex and involves multiple neurochemical processes.

The distance of 39.3 kg mass from 536 kg mass will be .0567d to have zero force of attraction.

The force of attraction between any two bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their masses.

If the cannon is fired after being filled with gunpowder, the following situations could occur.

The masses are

m₁ = 313 kg

m₂ = 536 kg

m = 39.3 kg

So as per sum if the distance between m₁ and m₂ is d and distance between m and m₂ is s then

The gravitational force between m₁ and m is equal to gravitational force between m and m₂.

\(\frac{G*m\x_{1} *m }{(d-s)\x^{2} } =\frac{G*m\x_{2} *m }{s\x^{2} }\)

⇒ m₁* s² = m₂ * (d-s)²

The heat anticipator in a thermostat prevents the temperature in the conditioned space from rising above the thermostat setting. This statement is false.

A thermostat is a temperature-regulating device that maintains a constant temperature in a heating and cooling system. When the temperature reaches a certain level, the thermostat causes the system to turn on or off. It is an important part of an HVAC system since it helps maintain the temperature within a room or building.

The thermostat's heat anticipator is an electrical device that determines when to shut off the heating or cooling system before the set temperature is reached. It accomplishes this by adding a small amount of resistance to the thermostat's circuit, which results in a little current flowing through the heating element of the thermostat.

It reduces overshooting by turning off the heating or cooling system before it reaches the set temperature, ensuring that the space temperature does not go beyond the thermostat setting. So, in conclusion, the correct explanation is false because the heat anticipator helps to maintain the temperature from overshooting the thermostat setting.

Your average velocity is 64 mph. Hence, if you drove 48 miles in 45 minutes, you would drive 64 miles in an hour.

The average velocity is determined by dividing the change in displacement (∆d) by the change in time (∆t).

To determine how many miles you would drive in an hour, given that you drove 48 miles in 45 minutes, we need to convert the time to hours.

We know that the distance covered or displacement is 48 miles, and the time taken is 45 minutes.We know that 60 minutes is equal to 1 hour.

Therefore, we have to convert the time of 45 minutes to hours. To convert a time value from minutes to hours, we can achieve this by dividing the given value by 60. Thus, 45/60 = 0.75 hours.

Now that we have the time taken to cover a distance of 48 miles as 0.75 hours, we can now use the formula of velocity to calculate the average velocity.v = d/tv = 48/0.75v = 64 mph

Therefore, your average velocity is 64 mph. Hence, if you drove 48 miles in 45 minutes, you would drive 64 miles in an hour.

Answer:

The object will float better.

Explanation:

If you have basic knowledge on how it works, this question is relatively easy. Let's start by reviewing something. We already know that this object (let's assume it's a spaceship of sorts) is in orbit, meaning there is already a certain amount of gravity from Earth tugging on it. We also know that space has an effect on how this moves, so the two forces "balance" each other, allowing the object to stay at orbit rather than just drifting off. Now let's see the answers to see which makes more sense.

A. The object will stop moving.

The object can't stop moving. With gravity increasing, it would be impossible for that to happen.

B. The object will fly off into space.

This could only happen if the gravity were to decrease by a decent amount.

C. The object will smash into another object.

There is no other object mentioned in the question.

D. The object will float better.

This seems most likely as gravity would be pulling on the object a bit more, but probably not enough to bring it back to the ground. It might drop a bit lower into the exosphere.

The current, voltages, resistances of the circuits in problem 1, 2, and 3 are given by Ohm's law as follows;

Questions 1—3 In Problems

Ohm's law states that the current, I in a circuit or between two points in a circuit is proportional to the voltage, V, across the circuit or the part of the circuit.

Mathematically, V = I × R

Where;

R = The circuit resistance to current

1. The current in the hair dryer draws from the circuit = 10–A

The voltage of the circuit to which the hair dryer is connected = 120–V

From Ohm's law, we have;

V = I•R

R = V/I

I = 10 A

V = 120 V

Therefore;

R = 120 V/(10 A) = 12 Ohms

2. The battery resistance = 2 Ohms

The voltage of the battery = 1.5–V

The current in the circuit is therefore found as follows;

R = 2 Ohm

V = 1.5 V

The current, I = V/R

Therefore;

I = (1.5 V)/(2 Ohms) = 0.75 A

3. The current supplies by the battery, I = 0.25 A

The battery resistance, R = 48 Ohm

The voltage of the battery, V = I × R

Therefore;

V = 0.25 A × 48 Ohm = 12 V

a) The new surface area of one face will be 225.162 cm^2.

b) The volume of the iron cube at the final temperature of 80°C will be  3382.29 cm^3.

The thermal expansion of a solid material can be determined using the coefficient of linear expansion, which is a material property that relates the change in length to the change in temperature. For iron, the coefficient of linear expansion is approximately 1.2 x 10^-5 /°C.

a) To find the new surface area of a face when the temperature rises from 20°C to 80°C, we can use the formula:

ΔA = A_0 * α * ΔT

where ΔA is the change in surface area, A_0 is the initial surface area, α is the coefficient of linear expansion, and ΔT is the change in temperature.

For a cube with each side 15 cm long, the initial surface area of one face is 15 cm x 15 cm = 225 cm^2. The change in temperature is 80°C - 20°C = 60°C. Substituting these values and the coefficient of linear expansion for iron, we get:

ΔA = 225 cm^2 * 1.2 x 10^-5 /°C * 60°C = 0.162 cm^2

Therefore, the new surface area of one face will be 225 cm^2 + 0.162 cm^2 = 225.162 cm^2.

b) To find the volume of the iron cube at the final temperature of 80°C, we can use the formula:

ΔV = V₁ * β * ΔT

where ΔV is the change in volume, V₁ is the initial volume, β is the coefficient of volume expansion, and ΔT is the change in temperature.

For a cube with each side 15 cm long, the initial volume is 15 cm x 15 cm x 15 cm = 3375 cm^3. The coefficient of volume expansion for iron is approximately three times the coefficient of linear expansion, so we can use β = 3α.

Substituting these values and the change in temperature, we get:

ΔV = 3375 cm^3 * 3 * 1.2 x 10^-5 /°C * 60°C = 7.29 cm^3

Therefore, the volume of the iron cube at the final temperature of 80°C will be 3375 cm^3 + 7.29 cm^3 = 3382.29 cm^3.
