Answer:
Equal
Explanation:
Recall that KE = 1/2(m)(v²) and PE = mgh, where m is mass, g is gravity, v is velocity, and h is height.
When the bowling ball is first dropped, it has a maximum potential energy but minimum kinetic energy. The height is max, so the potential energy will be greatest. Velocity is 0, so kinetic energy will be 0.
When the bowling ball is half way through its fall, the height will be half the initial height and the velocity will be half of the final velocity.
When the bowling ball is at the bottom and reaches the ground, the height is 0 so potential energy is 0 while the kinetic energy is max because velocity is the greatest.
Answer:
v = 0.352 m/s
Explanation:
To calculate escape velocity,
( P.E. + K.E ) at the surface of the asteroid = ( P.E. + K.E ) at the infinity
Here infinity is refered as the point wjich does not feel the gravitational potential of the asteroid,
For minimum velocity the K.E at infinity = 0
-GMm/r² + = 0 + 0
v² = 2GM/r² = 2 × 6.674×10⁻¹¹×7.2×10¹⁶/(8800)²
v = 0.352 m/s
Answer with explanation:
The given vectors in are reduced to their componednt form as shown
For vector A it can be written as
Similarly vector B can be written as
Hence The sum and difference is calculated as
The direction is given by
with positive x axis.
Similarly
The direction is given by
with positive x axis.
D because there no way it will reflect making the way come back
Answer: A circuit is electric wire that sends connection and signals to other bulbs or batteries that are connected to the circuit. There’s two different kinds of circuits, Series Circuit and Parallel Circuit.
Explanation: This is because Circuits is a term used in physic s
