An apple falling to the ground is not an example of centripetal acceleration.
Answer:
option b
Explanation:
from the given formula, s=d/t
make t the subject of the formula we have
t=d/s
5/100
0.5
Answer:
Approximately .
Assumption: the ball dropped with no initial velocity, and that the air resistance on this ball is negligible.
Explanation:
Assume the air resistance on the ball is negligible. Because of gravity, the ball should accelerate downwards at a constant near the surface of the earth.
For an object that is accelerating constantly,
,
where
- is the initial velocity of the object,
- is the final velocity of the object.
- is its acceleration, and
- is its displacement.
In this case, is the same as the change in the ball's height: . By assumption, this ball was dropped with no initial velocity. As a result, . Since the ball is accelerating due to gravity, .
.
In this case, would be the velocity of the ball just before it hits the ground. Solve for
.
.
Use the equation I=V/R where I is current and V is the voltage plus R is the resistance so when voltage is the highest and resistance is lowest the current is the highest
Answer: One neutron
Explanation:
one neutron 1/0n
Sum up the mass numbers on the right 99 + 135 + 2 = 236.
The sum of the mass numbers on the left should equal 236. 235 + 1 = 236
