A Skydiver Dives From An Airplane. Air Resistance Is Measured Each Second Following The Skydivers Jump.

Answers

Answer 1

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer 2

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

Which of the following levers would give them the MOST mechanical advantage for lifting the 500 kg tree?

PLS HELP

Answers

Answer:

Its either option (C) or Option (D)

Explanation:

In Option (C) there is least load distance and highest effort distance and when effort distance is more it is easier to work because effort is multiplied.

And if you are talking about most Mechanical Advantage option (D) could be the answer as the load distance is 3m and effort distance is 1m and when we divide 3/1 it comes 3.So, mechanical advantage is 3 which is greatest of all.
