The mass is 13.766 kilograms
Answer:
No.
Explanation:
No, all the pieces of paper did not remains waterproof because expansion of paper occur due to high temperature of hot water. We know that materials expand when they experience high temperature and contract when they observe cold temperature. So the pieces of paper remains waterproof which were put in cold water while those were not waterproof which were put in hot water.
Air drag is the frictional force which is due to air molecules and it is always opposite to the direction of motion
So here direction of air resistance is always opposite to the motion or velocity
Now if Car is travelling then the force on the car due to engine is always in the direction of velocity of car
Because here engine will provide the force to accelerate the car.
So opposite to that motion there is air resistance.
So here correct answer will be
<em>B) The forward force applied by the engine</em>
The law that accounts for that exact statement is the law that says that
most people don't understand these things very well.
A better statement is:
<span>"The gravitational forces between the Sun and each planet cause each planet
to move in an elliptical path."<span>
The laws that account for that behavior are:
-- Newton's second law of motion: (Force) = (mass) x (acceleration)
-- Newton's law of universal gravity</span></span>
B. The moon is located between the Sun and Earth
