The initial velocity of a car that reached 32 m/s in 3.4 at a rate of 2.6 m/s  is 23.16 m/s.

Velocity is described as the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time.

The given parameters include:

final velocity: 32 m/s

time: 3.4 seconds

acceleration = 2.6 m/s

V = u + at

32 = u + 3.4 * 2.6

32 = u + 8.84

32- 8.84 = u

initial velocity = 23.16.

So the initial velocity of the car that travels 32m/s in 3.4 at a rtae of 2.6 m/s is 23.16 m/s.

The reason no energy-using device operates at 100% efficiency and some energy is lost as heat, is explained by (a) the second law of thermodynamics. This law states that in any energy conversion process, the entropy (disorder) of the system increases, which leads to some energy being lost as heat.

The second law of thermodynamics states that in any energy conversion process, some energy will inevitably be lost as heat, and this loss is unavoidable. The first law of thermodynamics, on the other hand, states that energy cannot be created or destroyed, but it can be converted from one form to another. The conservation of momentum law deals with the conservation of linear momentum in a system, while Darcy's law describes the flow of fluids through porous materials. Newton's third law of momentum states that for every action, there is an equal and opposite reaction.

Answer:

The weight of the person decreases.

Explanation:

Weight of person at sea level = 700 N

height = 10000m

We know that the weight is given by product of mass and the acceleration due to gravity.

The acceleration due to gravity at height is given by

\(g' =g\times \left ( \frac{R}{R+h} \right )^2\)

Where, R is the radius of earth and h is the height.

Now, as we go on heights , the acceleration due to gravity decreases, so the weight also decreases as we go on heights.

The upper control limit (UCLp) for the control chart is 0.290, rounded to three decimal places. The lower control limit (LCLp) is 0, rounded to three decimal places.

Based on the developed control limits, we cannot determine whether the process has been in control or not without additional information.

Control charts are used to monitor and control processes by analyzing data and identifying variations. In this case, the control chart is being used to monitor the number of defectives in a process. The question provides the control limits for the chart, which are the upper control limit (UCLp) and the lower control limit (LCLp).

The UCLp is the highest acceptable value for the proportion of defectives in the process, while the LCLp is the lowest acceptable value. In this case, the UCLp is given as 0.290, which means that if the proportion of defectives exceeds this value, it would be considered out of control. The LCLp is given as 0, indicating that there is no lower limit for the proportion of defectives.

However, the question does not provide any data or information about the actual proportion of defectives observed in the process. Without this data, we cannot determine whether the process has been in control or not. To make a determination, we would need to compare the observed proportion of defectives to the control limits provided.

Answer:

Yes cause he walks 6.7 miles

The displacement vector of the man is equal to 17.41 miles in the Northeast direction.

The displacement of an object can be defined as the shortest distance between two points. The displacement can be described as a vector quantity because contains both direction and magnitude. The displacement can be positive (+ve), negative, or zero and can change with time.

The distance is the total path traveled and is a scalar quantity as it has only magnitude, and no direction. The distance is always positive (+ve), it can never be equal to zero.

Given, a man moves 2.6 miles along AB in the East and then 6.7 miles North along BC.

The displacement (AC) of the man can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (2.6)² + (6.7)²

AC² = 6.76 +44.89

AC = 17.41 miles

Therefore, the displacement vector of the man is 17.41 miles.

Explanation:

Answer:

M g - T = NB         vertical force on box B

T - m g = NA         vertical force on box A

T must be uniform (same) throughout length of string

(M - m) g = NB + NA = (M + m) a        since F accelerates M and m

Note: one can enclose the entire system with no external forces

No net vertical force or horizontal force is present - the net vertical force is A + B + C - masses of these objects * g

One would write a = (M - m) * g / (M + m)

The masses and tensions influence the accelerations of the boxes while considering friction and normal forces on block C.

When box A and B are released, their accelerations can be calculated using Newton's second law, (F = ma), where (F) is the net force and (a) is the acceleration.

The net force is the difference between the gravitational force (mg) and the tension in the rope (T).

For box A:

Net force: \(\rm \(F_{\text{net,A}} = T - mg\)\)

Using \(\rm \(T = m \cdot a_A\)\), where \(\rm \(a_A\)\) is the acceleration of box A:

\(\rm \(ma_A = T - mg\)\\\rm \(a_A = \frac{T}{m} - g\)\)

For box B:

Net force: \(\rm \(F_{\text{net,B}} = mg - T\)\)

Using \(\rm \(T = M \cdot a_B\)\), where \(\rm \(a_B\)\) is the acceleration of box B:

\(\rm \(Ma_B = mg - T\)\\\rm \(a_B = g - \frac{T}{M}\)\)

Now, considering friction and the normal force between block C and the ground:

The friction force \(\rm (\(F_{\text{friction}}\))\) can be calculated using the equation \(\rm \(F_{\text{friction}} = \mu N\)\), where \(\rm \(\mu\)\) is the coefficient of friction and (N) is the normal force.

The normal force (N) is equal in magnitude to the weight of block C \((mg_{C})\) since it's not accelerating vertically:

\(\rm \(N = mg_C\)\)

To summarize:

Acceleration of box A: \(\rm \(a_A = \frac{T}{m} - g\)\)

Acceleration of box B: \(\rm \(a_B = g - \frac{T}{M}\)\)

Friction force on block C: \(\rm \(F_{\text{friction}} = \mu mg_C\)\)

Normal force on block C: \(\rm \(N = mg_C\)\)

The masses and tensions influence the accelerations of the boxes while considering friction and normal forces on block C.

Sound waves travel through the air and can be blocked by walls. When a sound wave passes through a wall, the wall absorbs some of the sound energy, resulting in the higher-pitched sound waves being blocked more than lower-pitched sound waves.

This is because higher-pitched sound waves have shorter wavelengths, making them more susceptible to being blocked than lower-pitched sound waves, which have longer wavelengths.

This phenomenon is known as wave-particle duality, which states that sound waves have both particle-like and wave-like properties. The particle-like property of higher-pitched sound waves makes them more susceptible to being blocked by walls than lower-pitched sound waves. This is why you can hear lower-pitched sounds more clearly when they pass through a wall.

Answer:

Answer:

-1

Explanation:

An atom contains a proton, electron and neutron as subatomic particles. The number of protons, which is the positively charged particle (+) is always equal to the number of electrons, which is the negatively charged particle (-) in A NEUTRALLY CHARGED ATOM i.e. no charge.

However, a decrease or increase in charge is dependent on the number of electrons and protons in that atom. Sulfur atom has an electron number of 16 in its neutral atom, however, when it gains one more electron to become 17, it means that the charge has become -1 because the charge = number of protons - number of electrons i.e. 16 - 17 = -1.

Answer:

Acceleration, a = 12.18 m/s²

Explanation:

Given the following data;

Forward force = 12000N

Backward force = 2010N

Mass = 820kg

First of all we would find the net force.

Since the forces are acting in opposite direction, we would subtract the values of the forces.

Net force, F = Forward force - Backward force

Net force, F = 12000 - 2010

Net force, F = 9990N

Now, to find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

\( F = ma\)

Where;

Making acceleration (a) the subject, we have;

\(Acceleration (a) = \frac{F}{m}\)

Substituting into the equation;

\(Acceleration (a) = \frac{9990}{820}\)

Acceleration, a = 12.18 m/s²

An 820 kg car that experiences a 12,000 N force forward and a 2,010 N force backward has an acceleration of 12.2 m/s².

A car experiences a 12,000 N force that pushes it forward and a 2,010 N force that pushes it backward. The net force (F) acting on the car is the difference between both forces.

\(F = 12,000 N - 2,010 N = 9,990 N\)

An 820 kg (m) car experiences a net force (F) of 9,990 N. We can calculate the acceleration (a) of the vehicle using Newton's second law of motion.

\(F = m \times a \\\\a = \frac{F}{m} = \frac{9,990N}{820kg} = 12.2m/s^{2}\)

An 820 kg car that experiences a 12,000 N force forward and a 2,010 N force backward has an acceleration of 12.2 m/s².

The power of the pump is calculated by dividing the work done by the time taken. In this case, the pump does 1960 Joules of work in 10 seconds, which results in a power of 196 Watts. The power of the pump is 1960 Watts.

We can calculate the power of the pump using the formula:
Power = Work done / Time taken. First, we need to calculate the work done by the pump. Work done is equal to the force applied multiplied by the distance traveled in the direction of the force. In this case, the force applied by the pump is the weight of the water being pumped, which is equal to the mass of the water (we'll assume it's 50 kg for simplicity) multiplied by the acceleration due to gravity (9.81 m/s^2). So, the force applied by the pump is:
Force = 50 kg x 9.81 m/s^2
     = 490.5 N

First, we need to calculate the work done. Work done is given by the formula:
Work = mass × gravity × height
where mass = 50 kg, gravity = 9.8 m/s² (approx.), and height = 4 m.
Plug in the values into the formula:
Work = 50 kg × 9.8 m/s² × 4 m = 1960 Joules
Now, we need to calculate the power of the pump. Power is given by the formula:
Power = Work / Time
where Work = 1960 Joules and Time = 10 s.
Plug in the values into the formula:
Power = 1960 Joules / 10 s = 196 Watts

The flaw in the experiment on water recycling is that the student did not see water dripping off the glass plate as expected. To correct this flaw, the student should use a cold glass plate instead of a hot glass plate.

The correct option to the given question is option 4.

When the student holds the hot glass plate above the beaker, the water vapor in the atmosphere will come into contact with the cold surface of the plate and condense, forming water droplets. However, if the glass plate is already hot, it will not be able to cool down the water vapor quickly enough for condensation to occur.

By using a cold glass plate, the temperature difference between the plate and the water vapor will be greater, allowing for faster condensation. This will result in water droplets forming on the glass plate and dripping off, demonstrating the process of water recycling through the atmosphere.

Therefore, the correct method to correct the flaw in this experiment is to use a cold glass plate instead of a hot glass plate. This will enable the student to observe water droplets on the glass plate as expected.
