Answer:
Radiation moves out of the microwave into waves causing heat.
Explanation:
Inside your microwave oven, electrical energy is transformed into EM energy in the magnetron. When the microwave photons interact with food, food molecules are physically agitated, transforming the EM energy into kinetic energy, or energy of movement .

<span>Scientists have obtained most of this information from natural geological activity.
</span>S-waves and p-waves are seismic waves- the waves of energy that travel through the Earth as a result of an earthquake .Both P- and S-waves travel easily through solids, but S-waves cannot pass through liquids, and they cannot pass through the outer core. Scientists know that Earth’s outer core is liquid because s-waves are not able to pass through it.<span> When an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive.
</span>So, one of the reasons <span>why scientists believe the outer core is liquid is the s-wave shadow zone.</span>
The answer to the question is A
Answer:
The speed of elephant must be 1.4 m/s.
Explanation:
Mass of the elephant, M = 2800 kg
Mass of sprinter, m = 77 kg
Speed of sprinter, v = 8.5 m/s
It is required to find the speed of elephant to have the same kinetic energy as that of sprinter. So,
So, the speed of elephant must be 1.4 m/s.
The answer to this question is that work is defined as the change in energy. It measures the change in energy. W = ΔE.
