Mechanical advantage = (output force) / (input force)
MA = (2,000 N) / (120 N)
<em>MA = 16.67</em> (16 and 2/3)
Answer:
b. Static > sliding > rolling friction.
Explanation:
Static friction is greater than sliding friction. It takes more force to get an object to start sliding than to keep it sliding.
Sliding friction is greater than rolling friction. There are fewer points of contact for a round surface compared to a flat one.
You use more significant figures. 5 sigfigs (1.0985) is more accurate than 2 sigfigs (1.0)
Answer:
option B
Explanation:
Radius of new planet,R' = 2R
Mass of the earth, M' = 2 M
R and M is the Radius and Mass of the earth.
Weight of the person on earth = 500 N
Weight of the person in the new planet = ?
We know acceleration due to gravity is calculated by using formula
now, acceleration due to gravity on the new planet
here acceleration due to gravity is half in new planet, so weight will also be half on the new planet.
Weight on the new plane is equal to = 250 N
correct answer is option B
