Answer:
The number of grains of sand on all the beaches on Earth
Explanation:
if we assume grain of sand has an average size , then the number of grains of sand on all the beaches on Earth is roughly
The total number of stars in the observable universe is roughly equivalent to 1 billion trillion. which is roughly equal to the number of grains of sand on all the beaches on Earth.
The average it the constant speed.
Answer:
The force is 15N
Explanation:
The formula is Force= mass × velocity.
From the question mass is 5kg, velocity is 3m/s.
F= 5×3
F= 15Newton.
Therefore the force is 15N.
