Answer:
17 m
Explanation:
Work done is the product of force and perpendicular distance moved, therefore, expressed as
W=Fd
Where F represent the applied force, d is perpendicular distance and W is work done.
Making d the subject of the formula then
Substituting 68 J for work and 4 N for force then
Therefore, the distance is equivalent to 17 m
The earth all the way around is 196.9 million miles
Answer:
Explanation:
Gravity is a field force since the earth does not have to actually “touch” an object to pull it toward the earth. A magnetic force is a field force that attracts or repels another magnet. Likewise, electric charges cause attracting or repelling forces without actual contact between the charges
Answer:
B.the same as Lily's.
Explanation:
When a disc is rotating on its axis uniformly with some angular velocity , every particle on it rotates with the same angular velocity , because every particle on it completes a rotation simultaneously . So in one rotation they take same time . Hence particles whether on the outer edge or near the axis , all have same angular velocity .
They but differ due to their different linear velocity . Linear velocity of particle near outer edge have greater magnitude. .
B.
