It is false. The effect of freezing is almost the exact opposite
Answer:
The duration of the movie is longer than 2 hrs.
Explanation:
Given:
The duration of the movie observed by the crew on the spacecraft is 2 hrs.
According to time-dilation formula:
Here, 
is the required time, 
is the original time, 
is the velocity of the spacecraft and 
is the velocity of light.
Since 
, so 
.
So the time required will be large.
Answer:
a. 240 N due east
b. 540 N due west
Explanation:
Let east be the reference direction
(a) if the resultant force has a magnitude of 390 N and points east, and the 1st force is 150N due East, then the additional force would also due east and has a magnitude of
390 - 150 = 240 N
(b) if the resultant force has a magnitude of 390 N and points west, it would be -390N is eastern reference, and the 1st force is 150N due East, then the additional force would also due east and has a magnitude of
-390 - 150 = -540 N
This force would point west
Answer:
They slow down.
Explanation:
The collided so the slow down till they stop.
1# The ball flying through the air has two types of energy, kinetic from its velocity and potential from its height off the ground.
