Explanation

since they are weighted different, they will have more or less force (more mass=more force), also the heavier an object, the greater its acceleration while falling.

A student was sitting motionless in class. Which of the following explains why the student remains motionless?

A - There are no forces acting on the student.
B - The only force acting on the student is gravity pulling down.
C - The forces acting on the student are balanced.
D - The chair is the only force acting on the student, keeping them still.

Answers

The answer is C, because if the forces are balanced nothing moves.

Answer:

THE ANSWER IS C

Explanation:

In order to ride a bike up a hill with increasing speed—

the rider’s pedal force must be less than friction and the force of gravity
the rider’s pedal force must be equal to than friction and the force of gravity
the rider’s pedal force must be greater than friction and the force of gravity
It is impossible to ride up a hill with increasing speed.

Answers

Answer: the rider’s pedal force must be greater than friction and the force of gravity

Explanation:

This is because if the pedal force was less, you would go slower, and it is obviously not impossible to ride up a hill without increasing speed. But if the force was greater, your speed would increase.  

In which of the following situations will the ball have the greatest acceleration?



A golf ball with a mass of 0.045 kg is struck with a force of 1 N

A baseball with a mass of 0.142 kg is hit with a force of 5 N.

A soccer ball with a mass of 0.45 kg is kicked with a force of 20 N.

What is the effect of the mass of an object on it’s friction threshold?

Answers

An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface and the light object.

Jonas and his family are moving to another part of the city. As Jonas, his brother, and his Dad were driving one of the trucks filled with furniture to their new home, the truck ran out of gas. A gas station is 0.5 miles down the road. The three of them decide they need to somehow get the truck to the gas station to get gas. Jonas tries pushing the truck, but can not make it move. Which of the following would NOT be a solution to help get the truck to the gas station?


Unload the furniture out of the truck. With less mass, they should be able to push the truck to the gas station.

Jonas and his brother push the truck. With more force, they should be able to push the truck to the gas station.

Jonas’ brother gets out of the cab of the truck and sits in the back of the truck with the furniture. With less mass, they should be able to push the truck to the gas station.

Which number indicates how the moon is seen from earth during the second week of the lunar cycle?

Answers

5, sorry this is the answer but i need more words hah




During the second week of the lunar cycle, the moon is seen as a waxing gibbous, which appears as a mostly illuminated disc with a small portion of darkness on one side.

What is lunar cycle?

The lunar cycle, also known as the lunar phase or the phases of the moon, refers to the regular and predictable changes in the appearance of the moon as seen from Earth.

The lunar cycle is driven by the changing relative positions of the Earth, moon, and sun, and it typically lasts approximately 29.5 days. During this time, the moon goes through a sequence of eight different phases, including new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent, before returning to the new moon phase.
