Answer:
Explanation:
given,
Area of rectangular loop = 0.15 m²
Magnetic field = B = 0.20 T
angle between magnetic field and the normal to the plane = π/2
increasing at the rate = 0.60 rad/s
magnitude of emf induced = ?
induce emf through the loop
Φ = BA cos θ
now substituting all the given values
the magnitude of induced emf is equal to
Answer:
Air Resistance
Explanation:
If you were to drop both items on a plant without an atmosphere, they would both hit the ground at the same time. Since a feather doesn't have much mass compared to the hammer, it takes more time for the feather to "push" itself through and overcome the opposite push from the air
Answer: A, protons
Why: it just is
When an object moves its length contracts in the direction of motion. The faster it moves the shorter it gets in the direction of motion.
The object in this question moves and then stops moving. So it's length first contracts and then expands to its original length when the motion stops.
The speed doesn't have to be anywhere near the speed of light. When the object moves its length contracts no matter how fast or slow it's moving.
