Answer:
option B
Explanation:
Radius of new planet,R' = 2R
Mass of the earth, M' = 2 M
R and M is the Radius and Mass of the earth.
Weight of the person on earth = 500 N
Weight of the person in the new planet = ?
We know acceleration due to gravity is calculated by using formula
now, acceleration due to gravity on the new planet
here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.
Weight on the new plane is equal to 
= 250 N
correct answer is option B
Water - helps with dehydration.
instruction - help you understand how you need to do the workout.
trainers - wether it's an online trainer or a gym trainer they always say how to be safe while working out.
Answer:
c. Eggs of earthworms
Explanation:
The actual formation of earthworms is by existing earthworms laying eggs.
The other answers are all separate from earthworms, though they are all found in the area with the earthworms.
Rock fragments that are cemented together and compacted over time turn into sedimentary rock.
the whole process can be summed up as the combination of weathering of rocks to form sediments, transport of the sediments to form deposits, cementation of deposits to forms the sedimentary rocks.
Ball b has eight times more kinetic energy than ball a, which has half its mass. The speed ratio is 4.
<h3>What exactly does kinetic energy mean?</h3>
Force must be applied to object in order to accelerate. To apply a force, we must work hard. Because energy has been transferred to the object, it will be moving at a new, constant speed once the operation is finished.
Given,
Two balls a and b
and the mass of ball an is half that of ball b..
Kinetic energy of ball a is eight times kinetic energy of ball b.
mₐ = 
KEₐ = 8 KE
Kinetic energy is measured by,
KE = 1/2 mv²
KE ratios for both balls a and b are calculated,
∴ 
= 
= 
16 = 
= 4/1
