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 .

(9) The force needed to make the object fall on Earth is 127.4 N.
(10) The mass of the object falling at the acceleration due is 1.94 kg.
(11) The force required for feather is 0.98 N and the force required for the bowling ball is 44.1 N
(9) The force needed to make the object fall on Earth is calculated form Newton's second law of motion.
F = mg
where;
- <em>m is the mass of the object = 13 kg</em>
- <em>g is acceleration due to gravity = 9.8 m/s²</em>
<em />
F = 13 x 9.8 = 127.4 N
Thus, the force needed to make the object fall on Earth is 127.4 N.
(10) The mass of the object is calculated from Newton's second law of motion.
F = mg
Thus, the mass of the object falling at the acceleration due is 1.94 kg.
(11) The force required to make each of the objects fall is calculated from Newton's second law of motion.
Force required for feather: F = 0.1 x 9.8 = 0.98 N
Force required for the bowling ball: F = 4.5 x 9.8 = 44.1 N.

To solve this problem we will apply the concepts related to Ohm's law and Electric Power. By Ohm's law we know that resistance is equivalent to,
Here,
V = Voltage
I = Current
While the power is equivalent to the product between the current and the voltage, thus solving for the current we have,
Applying Ohm's law
Therefore the equivalent resistance of the light string is
If you're talking about the <em>splitting</em> of an atom, the process is called Nuclear Fission.
Answer:
<em>Physical change is a temporary change. A chemical change is a permanent change</em>
<em>examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.</em>
