<u>Answer;</u>
<em>D. The object’s weight changes, but its mass stays the same.</em>
<u>Explanation;</u>
- Mass is the amount of matter in a object, which is measured in kilograms. Mass of an object is measured using a beam balance. It is important to note that the mass of an object or a body remains constant, and does not vary from one place to another. For instance the mass of a person on the moon will be the same as when the person is on the earth surface.
- Weight on the other hand is the measurement of gravitational pull of an object. weight is measured using a spring balance and measured in Newtons. Weight varies from one place to another depending on the gravitational pull of a given surface.
Answer:
The length of the wire is 2.86 m
Explanation:
Given:
Current A
Magnetic field T
Force N
Angle between wire and magnetic field 46°
The magnetic force on the current carrying wire is given by,
Where length of wire
m
Therefore, the length of the wire is 2.86 m
Answer:
B) μ = 0.23
Explanation:
The coefficient of friction is equal to μ = F / N where μ (mu) is the coefficient of friction, F is the friction force, and N is the normal force (the force of an object being applied onto the earth by gravity).
F, the friction force, is given as 67 N
Since the weight of the crate is 289 N, that means the normal force is 289 N.
This means that the coefficient of friction is μ = F / N = 67 N / 289 N = 0.23183391 = 0.23
Therefore, B is the correct answer
