What? do you have a question??
The answer is A I believe. Hope this helps!
Answer:
The centripetal force on body 2 is 8 times of the centripetal force in body 1.
Explanation:
Body 1 has a mass m, and its moving in a circle with a radius r at a speed v. The centripetal force acting on it is given by :
Body 2 has a mass 2m and its moving in a circle of radius 4r at a speed 4v. The centripetal force on body 2 is :
So, the centripetal force on body 2 is 8 times of the centripetal force in body 1.
Answer:
600 N
Explanation:
From the question given above, the following data were:
Mass (m) = 60 Kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?
The weight of an object is related to its mass according to the following equation:
Weight = mass × Acceleration due to gravity
W = m × g
With the above formula, we can obtain obtained the weight of the boy as follow:
Mass (m) = 60 Kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?
W = m × g
W = 60 × 10
W = 600 N
Therefore, the weight of the boy on Earth is 600 N
