Missing information:
The mass of the object is 15 kg.
Answer:
18.7 m
Explanation:
The gravitational potential energy of an object is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the heigth of the object, relative to the ground
In this problem, we know:
U = 2750 J is the potential energy of the object
m = 15 kg is the mass of the object
Solving for h, we find the height of the shelf:
"a black hole forms when any object reaches a certain critical density, and its gravity causes it to collapse to an almost infinitely small pinpoint."
I know its not straight forward with the answer
Explanation:
Assuming the strength training sessions last roughly 20 minutes each, that breaks down to about three hours of exercise a week. According to these recommendations, beginner exercisers should work up to three to four 40-minute gym sessions per week.
Answer:
Torque
Explanation:
loosening loosening a boat requires a certain amount of torque which is the product of the force acting on the wrench and the moment arm, or distance from the center of rotation at which the force is applied. the longer the handle, the last force it takes to generate the same amount of torque
