Every action force has an opposite and equal reaction force. Determine which of these are action/reaction pairs. Check all that

apply. A girl leans against a wall and the wall pushes on the girl. A baseball hits a glove and the glove pushes on the ball. A boy pushes on a door and the door swings open. A soccer player kicks a ball and then another soccer player kicks the same ball. A cat rubs up against a tree and the tree pushes against the cat. A student pushes another student standing in a line, and that student falls into the next student.

Imagine that you drop an object of 10 kg, how much will be the acceleration and
Lelu [443]

If you do this on Earth, then the acceleration of the falling object is 9.8 m/s^2 ... NO MATTER what it's mass is.

If its mass is 10 kg, then the force pulling it down is 98.1 Newtons. Most people call that the object's "weight".

A cloud is drifting across the sky at a constant velocity of 724metersperminute to the east. It is at an altitude of 9,200 meter
alisha [4.7K]

Answer:

The cloud moves 9050 meters to the east in 12.5 minutes.

Explanation:

Let suppose that mass of the cloud is negligible. meaning that effects of gravity are negligible and that altitude of the cloud remains constant. If the cloud drifts at constant velocity, travelled distance is defined by following formula:

\Delta s = v\cdot \Delta t (1)

Where:

v - Velocity, in meters per second.

\Delta t - Time, in seconds.

If we know that v = 724\,\frac{m}{min} and \Delta t = 12.5\,min, then the travelled distance after 12.5 minutes is:

\Delta s = 9050\,m

The cloud moves 9050 meters to the east in 12.5 minutes.

A lightweight ball is thrown horizontally. What forces act on the ball just after being released from the thrower's hand
algol [13]

The forces acting on a ball just after it's released from the thrower's hand is <u>gravity</u>.

<h3>What is a force?</h3>

A force refers to a push or pull of an object such as a ball, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.

<h3>What is gravity?</h3>

Gravity can be defined as a force of attraction that controls the movement of an object such as a ball and the planets around the Sun.

In this scenario, the forces acting on a ball just after it's released from the thrower's hand is a force of <u>gravity</u> or gravitational force since it was thrown horizontally.
