Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. ... The two vibrating fields together form an electromagnetic wave.
<h2>Hey there!</h2>
The Force "F" applied on the unit electric charge "q" at a point describes the electric field.
<h3>☆ Formula to find electric charge:</h3>
<h2>Hope it helps </h2>
The wavelengths of radio waves are much "Longer" than the wavelength of microwaves therefore, radio waves carry much "Lower" <span>energy than a microwave.
Hope this helps!</span>
Answer:
Explanation:
Momentum is the product of mass and velocity.
The mass of the truck is 2,000 kilograms and the velocity is 35 meters per second.
Substitute the values into the formula and multiply.
The truck's momentum is <u>70,000 kilograms meters per second.</u>
Answer:
120 N
Explanation:
F=ma therefore 60kg times 2m/s^2 is 120 N
