The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

Force applied on the block: F = 40 N.

Displacement of the box = 10 m.

Explanation:

(a) The atmospheric pressure as measured by the barometer Q can be calculated using the formula:

P = ρgh

where P is the pressure, ρ is the density of mercury, g is the acceleration due to gravity, and h is the height of the mercury column in the tube F. Since the space above the mercury column is a vacuum, there is no pressure exerted on the top of the column. Therefore, the pressure measured by the barometer is equal to the atmospheric pressure, which is given by:

P = ρgh = (14 × 10³ kg/m³) × (0.76 m) × (10 N/kg) = 106,240 Pa

Therefore, the atmospheric pressure as measured by the barometer Q is 106,240 Pa.

(b) The pressure at point E can be calculated using the formula:

P = ρgh

where P is the pressure, ρ is the density of mercury, g is the acceleration due to gravity, and h is the height of the mercury column above point E. From the diagram, we can see that the height of the mercury column above point E is 0.86 m. Therefore, the pressure at point E is:

P = ρgh = (14 × 10³ kg/m³) × (0.86 m) × (9.81 N/kg) = 120,965 Pa

To convert this pressure to mm Hg, we can use the conversion factor:

1 Pa = 0.0075 mm Hg

Therefore, the pressure at point E is:

P = (120,965 Pa) × (0.0075 mm Hg/Pa) ≈ 907 mm Hg

(c) When barometer P is brought up to the mountains, the atmospheric pressure decreases. As a result, the height of the mercury column in the tube will also decrease. This is because the pressure difference between the top and bottom of the column is proportional to the height of the column, according to the formula P = ρgh. As the atmospheric pressure decreases, the pressure at the top of the column decreases, and the column of mercury will fall until the pressure difference between the top and bottom of the column is equal to the new atmospheric pressure. Therefore, we expect the column of vacuum in P to decrease in height as the barometer is brought up to the mountains.

Answer:

B)Lead is a solid at 310 °C

Explanation:

The melting point of a substance refers to that temperature in which the substance changes state from solid to liquid. The melting point of a substance, which is usually a temperature value, is that actual temperature the change of state occurs.

According to this question, the melting point of Lead (Pb), which is naturally a solid metal, is 327.5°C. This means that LEAD (Pb) will only change to its liquid state at exactly 327.5°C and above. Therefore, at a temperature of 310°C, which is lower than lead's melting point, Lead element will still be a solid.

Answer: The correct answer is B. Lead is a solid at 310

The direction of the angular displacement of the wheel is -Toward you.

The definition of angular displacement is "the angle, expressed in radians (degrees, revolutions), through which a point or line has been rotated in a particular sense about a certain axis." It is the angle at which a body travels around in a circle.

A vector quantity, angular velocity has both a magnitude and a direction. The direction matches the direction of the angular displacement, which is where we derived the angular velocity.

The rate at which angular velocity changes over time is referred to as angular acceleration. Typically, it is stated in radians per second per second. As a result, d = d t. The term "rotational acceleration" also applies to the angular acceleration.

The tension in the cable is 35400 N. To find the speed of the pulse, we can use the formula: speed = distance/time.

The distance traveled by the pulse is twice the length of the cable, since it travels the length of the cable and then returns. Therefore, the distance traveled is:

2 x 660 m = 1320 m

The time taken is given as 19 s. So, we can calculate the speed as:

speed = 1320 m/19 s = 69.47 m/s

To find the tension in the cable, we can use the formula:

tension = (mass x gravity) + (stress x area)

Since we do not know the mass of the cable, we can assume it to be negligible. The stress in the cable can be found using the formula:

stress = force/area

where force is the force applied to the cable, and area is the cross-sectional area of the cable. We can assume that the force applied is equal to the tension in the cable. The area can be found using the formula:

area = π x (diameter/2)^2

Substituting the values, we get:

area = π x (0.015/2)^2 = 1.77 x 10^-4 m^2

Now, we can find the stress as:

stress = tension/area

Substituting the value of stress as 2 x 10^11 N/m^2 (for steel cables), we can calculate the tension as:

tension = stress x area = 2 x 10^11 N/m^2 x 1.77 x 10^-4 m^2 = 35400 N

Therefore, the tension in the cable is 35400 N.

Answer:

At point A;

GPE = 58800 J

KE = 0 J

At point B;

GPE = 44100 J

KE = 14700 J

At point C;

GPE = 0 J

KE = 58800 J

At point D;

GPE = 29400 J

KE = 29400 J

EPE = 29400 J.

Explanation:

The Gravitational Potential Energy, GPE, is given as follows;

GPE = The mass. m × The acceleration due to gravity, g × The elevation or height, h

∴ GPE = m × g × h

The Kinetic Energy, KE = 1/2  × The mass × The square of the velocity, v²

KE = 1/2 × m × v²

At point A;

The parameters are;

h = 100m, v = 0 (Starting point), Cart mass, m = 60 kg, we have;

GPE = m × g × h = 60 × 9.8 × 100 = 58800

GPE = 58800 J

KE = 1/2 × m × v² = 1/2 × 60 × 0² = 0

KE = 0 J

Mechanical Energy, ME = GPE + KE = 58800 + 0 = 58800 = Constant

ME = 58800 J

At point B;

GPE = 60 × 9.8 × 75 = 44100

GPE = 44100 J

KE = ME - GPE = 58800 - 44100 = 14700

KE = 14700 J

At point C;

GPE = 60 × 9.8 × 0 = 0 J

KE = ME - GPE = 58800 - 0 = 58800

KE = 58800 J

At point D;

v = 0, the Cart is brought to rest by the spring

GPE = 60 × 9.8 × 50 = 29400

GPE = 29400 J

KE = ME - GPE = 58800 - 29400 = 29400

KE = 29400 J

The Elastic Potential Energy EPE gained by the spring = KE = 29400

EPE = 29400 J.

Answer:

The mass of the reactants will always equal the mass of the products.

Explanation:

If an equation is provided choose the one that has the same number of atoms on each side.

The equation F=ma, where F is the net force, m is the mass, and an is the acceleration, can be used. . Rearranging the formula to solve for mass, we get m=F/a. Substituting the given values, we get m=12 N/48 m/s^2 = 0.25 kg. Therefore, the answer is A) 0.25 kg.

To solve this problem, you can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). In this case, the net force (F) is 12 N, and the acceleration (a) is 48 m/s². You are asked to determine the mass (m) of the hockey puck.

Using the equation F = ma, you can rearrange it to find the mass: m = F/a

No, I would not recommend the use of 316 stainless steel alloy for a turbine blade application that will operate at 1350°C because the operating temperature is very close to the melting point of the alloy.

This could cause the material to deform or fail due to thermal stress and fatigue, potentially leading to catastrophic failure of the turbine blade.

A material with a higher melting point and better high-temperature mechanical properties, such as a nickel-based superalloy, would be more suitable for this application.

Zero resistance or capacitance value corresponds to a short circuit, which is the travel of current along an unintended path.

True short circuits happen when electrical circuit wires or wire connections are exposed or broken; they need to be identified and addressed as soon as possible. When there is a low resistance connection between two conductors supplying electricity to a circuit, a short circuit happens.

A "ideal" open circuit would have zero capacitance. A capacitor with 0 capacitance has no electrical charge accumulating on its plates or conductors. Zero capacitance means it can become fully charged as soon as the current is flown through it.

The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that may be held in a capacitor to the applied voltage V across its plates. In other terms, capacitance is the capacity of the device to store the most charge per volt:
