Answer:

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position.

Explanation:

An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

Answer:

Explanation: I plugged it on the formula

Coyote should drop the anvil when the Roadrunner is 20.3 meters away from the cliff.

The velocity of the object is defined as the fraction of the displacement of the object over a period of time.

We can solve this problem by finding the time it takes for the anvil to fall from the cliff to the ground, and then using that time to find how far the Roadrunner has travelled during that time.

First, we need to find the time it takes for the anvil to fall from the cliff. We can use the equation:

d = 1/2 x  g  x t²

where d is the distance (40.0 meters), g is the acceleration due to gravity (9.81 m/s^2), and t is the time.

Solving for t, we get:

t = √(2d/g)

t = √(2 x 40.0/9.81)

t = 2.03 seconds

So it takes 2.03 seconds for the anvil to fall from the cliff to the ground.

During this time, the Roadrunner has travelled a distance equal to its velocity multiplied by the time:

distance = velocity x  time

distance = 10.0 m/s x 2.03 s

distance = 20.3 meters

Therefore, Wile E. Coyote should drop the anvil when the Roadrunner is 20.3 meters away from the cliff.

Answer:

Pressure =Area × height

0.01N/cm=300cm×height

height=0.01×300

The weight of the book is equal to 3N.

Pressure can be described as the ratio of the force exerted to the surface area over which the force is exerted. We can define pressure as the force applied perpendicular to the surface per unit area over which that applied force is distributed.

The SI unit of pressure can be represented as the pascal (Pa). A pascal is the force of one newton (N) exerted over a surface area of 1 m². Since the pressure is dependent on the area so the pressure can be increased and decreased without changing the force.

Given, the pressure on the book, P = 0.01 N/cm²

The area of the book, A = 300 cm²

Pressure = Force/ Area

Force = Pressure ×Area

Force = 0.01  × 300 = 3 N

Weight of the book, W = mg = 3 N

Answer:

Force arrows are used to represent both the magnitude and direction of forces. The length of the arrow corresponds to the magnitude of the force, with longer arrows indicating forces with larger magnitudes. The direction of the arrow corresponds to the actual direction that the force is being exerted. Force arrows are used by scientists and engineers to predict the motion of an object based on the forces that are applied to it.

Let's go back to Amil and his box for a moment. To represent the force that he is exerting on the box, we can draw the box and then show the force using a force arrow, like this:

Explanation:

How would our force arrow change if he pushed the box with twice as much force? Because the magnitude of the force is doubled, the length of the force arrow should also be doubled.

Now, what if he didn't push directly to the right, but instead his arms made a 30-degree angle with the ground? In that case, the direction of the force arrow needs to change to show the direction in which the force is applied.

Answer:

resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

Explanation:

assume that the ship started moving from A to B (north at 50km/hr for 2 hours) so the covered distance will be: 50*2 = 100 km

then it moves from B to C so the covered distance will be: 3*60 = 180 km

using Pythagoras, we get the resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

The truck applies the same force to the car that the car applies to the truck. The truck applies the same force to the car that the car applies to the truck. According to Newton's third law, action and reaction have the same magnitude and move in the opposite direction.

Force is an external agent that can change the state of rest or motion of a body. It has a magnitude as well as a direction.

The direction of the force is the point where force is applied, and the application of force is the point where force is applied.

The concept of force is commonly explained in terms of Isaac Newton's three laws of motion, which are laid out in his Principia Mathematica.

The truck exerts the very same force on the car as the car exerts on the truck. The truck exerts this very same force on the car as the car exerts on the truck.

Action and reaction have the same amplitude and move in the opposite direction, according to Newton's third law.

Thus, this can be the comparison in the given scenario.
