Question

in the first picture, what is being discussed in the \friction\ article? * 1 point
a hockey puck travels much slower on ice than on carpet because ice exerts much more friction on the puck than carpet does.
light does not create any friction in space.
on ice, a hockey puck can travel a long way with just one push.
generators and motors inside electrical power plants use oil to lubricate parts to ensure friction is reduced within the systems.
in the first paragraph, which of the following statements is discussed in the * 1 point \friction\ article?
theres one place where there is no friction at all to slow things down: space!
if you hit it with a hockey stick and then dont touch it, the puck slides across the carpet a bit, slows down, and then stops.
on earth, there is some friction caused by the air in the atmosphere. this friction is known as air resistance.
nuclear power plants do not have any equipment that causes any kind of friction.

Explanation:

1. Analyze each option based on the concept of friction. Ice has less friction than carpet, so a hockey - puck travels faster on ice, making the first option incorrect. Light is not related to the concept of friction in the context of solid - surface or mechanical friction, so the second option is off - topic. The third option correctly describes the low - friction property of ice for a hockey puck. The fourth option is about lubrication in power plants which is a different application context.
2. For the second set of options, space has no air or solid - surface friction to slow things down, which is a valid statement about friction. A hockey puck on carpet slows down due to friction, which is also correct. Air resistance is a form of friction on Earth, which is correct. Nuclear power plants have moving parts and thus friction, so the fourth option is incorrect.

Answer:

1. C. On ice, a hockey puck can travel a long way with just one push.
2. A. There's one place where there is no friction at all to slow things down: space!

B. If you hit it with a hockey stick and then don't touch it, the puck slides across the carpet a bit, slows down, and then stops
C. On Earth, there is some friction caused by the air in the atmosphere. This friction is known as air resistance
