The force between two charges objects is related to separation.
Answer:
v= - 4.507 i - 2.363 j
Explanation:
Given that
mc= 1490 kg
vc= 9.5 m/s ( - i)
mt= 1650 kg
vt = 6.4 m/s ( -j)
There is any external force so linear momentum will remain conserve.
Lets take final speed is v.
mc .vc + mt . vt = ( mc+mt) v
1490 x 9.5 ( - i) + 1650 x 6.4 ( -j) = ( 1490+1650) v
14,155 ( -i) + 10,560 ( - j) = 3140 v
v= - 4.507 i - 2.363 j
Answer:
C. Earth going around the sun.
Explanation:
Circular motion should have a center to repeat its motion.
<span>The answer to this question would probably be "</span><span>D. The same background radiation was observed coming from all directions of space."
The background radiation here is referring to the Cosmic Microwave Background Radiation, one of the observational evidences of the Big Bang Theory which was discovered by Penzias and Wilson as they were doing some observations with a microwave receiver. </span>
The answer is a bc electric is fast
