A car is moving at 12 m per 2nd and has a mass of 600 kg what is the kinetic energy of the car
Brrunno [24]

Answer:

43,200 Joules

Explanation:

Kinetic energy can be found using the following formula:

KE=\frac{1}{2}mv^2

where <em>m</em> is the mass in kilograms and <em>v</em> is the velocity in m/s.

We know the mass is 600 kilograms, and the car is moving at 12 meters per second. Therefore the mass is 600 kilograms and the velocity is 12 m/s.

<em>m</em>=600

<em>v</em>=12

Substitute these values into the formula.

KE=\frac{1}{2}600*12^2

First, evaluate the exponent: 12^2. 12^2 is the same as 12*12, which is equal to 144.

KE=\frac{1}{2}*600*144

Multiply 600 and 144

KE=\frac{1}{2}*86,400

Multiply 1/2 and 86,400, or divide 86,400 by 2.

KE=43,200

Add appropriate units. Kinetic energy uses Joules, or J for units.

KE=43,200 Joules

The kinetic energy of the car is 43,200 Joules.

During wave motion, the motion of particles to one side of the rest position will be (unrelated to,the same as) the motion to th
pentagon [3]
The motion of particles to one side of the rest position will be the same as the motion of the other side of the rest position in a wave motion. because in a wave motion or wave function, it symmetrical. meaning the motion on the other side will be identical to the other side of the rest position

How does the buoyant force affect a submerged object
NeX [460]

Answer:

The buoyant force is the pressure of the object being forced upward.  

<em>Weight of the object affects the buoyant force</em> of the submerged object; as weight is added to the object, it will cause the object to sink.  The more weight...the more it will sink.

If the weight is less than the buoyant force, it will cause the object to go up.

If the weight is the same as the buoyant force, the object will stay in the same position.
