Weight is the force that the gravitational exerts on a body given by the mass multiplied by the gravitational acceleration.
1 pound = 4.448 Newtons
The gravitational acceleration in Jupiter is 24.79 m/s² which is about 2.36 times that of the earth. Mass of a body remains constant everywhere.
Weight = mg
= 175 × 24.79
= 4338.25 Newtons
Then, 4338.25/4.448 = 975.326 pounds
Answer:
The correct option is momentum is conserved
Explanation:
A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; <em>acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system</em>.
This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.
Answer:
A., B. & C.
Explanation:
All apply, because all these happen in a plant.
Given:
Object in circular motion 25 m/s
1 second to go quarter circle
Required:
Centripetal acceleration:
Solution:
Acceleration = v2/r
Where v is the velocity and r is
the radian
Substituting the values into the
equation,
Acceleration = v2/r = (25
m/s)2/(4*pi/180) = 8952.47 m2/s2
