An object has 90000 J of kinetic energy and is moving at 12 m/s. what is the objects mass?
Klio2033 [76]

Answer:

1250kg

Explanation:

we can solve this using the formula for the Kinetic Energy

Kinetic.Energy=\frac{1}{2}*mass*velocity^{2}\\mass=\frac{2*Kinetic.Energy}{velocity^{2}}\\mass=\frac{2*90000}{12^{2}}\\\\mass=1250kg

What is a fuel?
Daniel [21]

Answer:

something that can be burned to produce heat

Explanation:

Combustion can be defined as an exothermic chemical reaction between physical substances, usually in the presence of oxygen and hydrocarbons to produce heat, light and carbon.

A fuel can be defined as something that can be burned to produce heat.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Ket [755]

Answer:

E =  1.64 x 10⁶ V/m

Explanation:

The electric field in the region between the plates can be given by the following formula:

E = \frac{\Delta V}{d}

where,

E = Electric Field = ?

ΔV = Poetential Difference across the plates = 23 KV = 23000 V

d = distance between plates = 1.4 cm = 0.014 m

Therefore, using these values in the equation, we get:

E = \frac{23000\ V}{0.014\ m}

<u>E =  1.64 x 10⁶ V/m</u>
