Answer:
2.1 × 10⁻⁵ T
Explanation:
Given:
Inner radius, r = 4 mm = 0.004 m
Outer radius, R = 25 mm = 0.025 m
Current, I = 4 A
Distance of the point from the center, a = 17 mm = 0.017 m
μ₀ = 4π × 10⁻⁷ T·m/A
Now,
For the hollow cylinder magnetic field (B) is given as:
on substituting the respective values, we get
or
B = 2.1 × 10⁻⁵ T
The answer is, "an unbalance force has acted on the vehicle". The vehicle will not change its states, unless otherwise there is a force acted upon on the object, that compel it to move in its original position, or to cause to change its direction of motion. This unbalance force cause the vehicle to move in the direction of the applied force.
Answer:
most light waves are scattered or are either reflected
Explanation:
the light waves bounce after hitting the mirror.
Answer;
B. Mass and energy are equivalent.
Explanation;
-Each of the letters of E = mc2 stands for a particular physical quantity.
E is the energy, m is the mass and c is the speed of light (m/s)
Energy = mass x the speed of light squared
-The equation E=mc2 explains nuclear fusion, how matter can be destroyed and converted to energy and energy can be converted back to mass. It explains the atomic energy produced by nuclear power plants and the atomic energy released by atomic bombs.
-The equation tells us that mass and energy are related, and, in those rare instances where mass is converted totally into energy, how much energy that will be.
The answer is C is the velocity is the same then the acceleration is also the same.
