An object has a kinetic energy of 32 J and a mass of 36 kg, how fast is the object moving?
marin [14]

Answer:

1.33 m/s

Explanation:

The formula for Kinetic Energy is given as:

K.E=\frac{1}{2} mv^{2} \\

Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.

Re-arranging the above equation and isolating v, we get

2 K.E = mv^{2}\\\\v^{2} = \frac{2 K.E}{m}

Putting values in this equation, we get:

v^{2}=\frac{2 \times 32}{36}\\\\ v^{2}=\frac{16}{9}\\\\ v=\frac{4}{3}\\\\  v=1.33

Thus, the object is moving with a velocity of 1.33 m/s

Which type of seismic wave is recorded by a sesimoraged first during an earthquake ?
inn [45]
There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.

(blank) is the thermal energy that flows from one substance to another when the substances differ in temperature.
ladessa [460]

The thermal energy can be defined as the type of kinetic energy which is generated due to the motions of the particles. This motion generates a temperature which can be measured easily. The type of thermal energy which flows from one substance to another when the temperature of the two substances is different is known as heat.

Hence, the blank can be filled with 'heat'.
