Fluid mechanics deals with pressure and internal forces in the fluid. So the correct answer should be a) how fluids do work.

If you put two solids in contact, there will be a contact force created between them. Since Pressure = Force / Area, the correct answer should be b) exert pressure on each other.

How far can you ride your bike if you ride for 10 min at a speed of 150 m/min
Contact [7]

Answer: 1500metres

This formula can be rearranged...

Speed = Distance ÷ time.

Time= Distance ÷ speed.

Distance= Time × speed.

In a basketball game, a player shoots a jump shot. What force actually causes the player to jump into the air? Question 3 option
Julli [10]

Option B is the correct answer.

In a basketball game, a player shoots a jump shot then the floor pushes up on the player.

<h3>Newton's Third Law</h3>

Newton's third law states that when two bodies interact with each other, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

In the given situation, a player shoots a jump shot. It means that the player pushes the floor downward direction.

Newton's third law is applicable in this situation where the player pushes the floor downward direction, at the same time the floor pushes the player upward. The amount of force applied to the floor by the player is equal in magnitude and opposite in direction as compared to the force applied to the player by the floor.

Hence the option B is the correct answer.

To know more about Newton's third law, follow the link given below.

Atomic mass for oxygen
masya89 [10]

Answer:

16

Explanation:

The atomic mass of an element is defined as the average of the isotopic masses, weighted according to the naturally occurring abundances of the isotopes of the element. Although oxygen has nine isotopes with mass numbers ranging from 13 to 21, oxygen-13, oxygen-14 and oxygen-15 are not naturally occurring isotopes. So, we do not need to include them when we calculate the relative atomic mass of oxygen.
