Answer:
A car would need to be moving with a velocity of 28.86 m/s for its acceleration to be numerically equal to the acceleration due to gravity.
Explanation:
Radial acceleration for an object in circular motion is given by
α = v²/r
α = g = 9.8 m/s²
v = ?
r = 85 m
9.8 = v²/85
v² = 9.8 × 85 = 833
v = 28.86 m/s
Answer:
greater with the brick wall
Explanation:
the impulse does not depend whether its a haystack or a brick wall because impulse is the products mass and velocity.
Answer : D) Circuit A
This circuit is the only circuit where it is not complete, having and open spot towards the bottom of it, making it and open circuit.
Electromagnetic radiation waves:
They can be either infared radiation or visible light
We cannot see I fared radiation but it is how some energy is transferred
