A hockey puck slides across a frozen pond. If ice friction and air resistance are neglected, the force needed to keep the puck sliding at constant velocity is the weight of the puck divided by the mass of the puck. the mass of the puck multiplied by 10 m/s2. 0 N. equal to the weight of the puck. none of the above

The force needed to keep the puck sliding at constant velocity is 0N

Explanation:

Since the ice friction and air resistance are neglected, the force needed to keep the puck sliding at constant velocity is 0N.

The acceleration due to gravity (g) will be zero since there is no ice friction and air resistance taken into consideration, and therefore,

F = m*g = m*0 = 0N

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
