Answer:
Red shift supports the big bang theory. ... The light from distant galaxies is red shifted (this tells us the galaxies are moving away from us) and the further away the galaxy the greater the red shift (this tells us that the more distant the galaxy the faster it is moving). Constellations look like they are moving because earth is rotating on it's axis.
May I have brainliest, please?
Work done by a given force is given by
here on sled two forces will do work
1. Applied force by Max
2. Frictional force due to ground
Now by force diagram of sled we can see the angle of force and displacement
work done by Max =
Now similarly work done by frictional force
Now total work done on sled
Answer:
Option C
Explanation:
Kinetic energy is the energy that the body possesses by virtue of its motion.
The formula for Kinetic energy is given by
Using this formula let us find kinetic energy for the bodies given and find out which is the greatest
A) KE =
B) KE =
C) KE =
D) KE =
Comparing these we find that 9mv^2 is the highest.
Hence option C is the answer.
The two letters are B and A, in that order.
Answer:
Explanation:
F = Force on the skier = 60 N
= Coefficient of friction = 0.05
w = Weight of skier
Force is given by
Weight of the skier on which the force is being applied is
.
