The amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles.
- What is electromagnetic wave:
Electromagnetic waves also called EM waves, are waves that are created as a result of vibrations between an electric field and magnetic field.
The formula of Intensity of electromagnetic wave:
- I = 1/2 ( c* ε(0)* E(0)^2 )
where c is speed of light
E is amplitude of electric field
here Intensity of EM waves doubles so,
I' = 2*I
we can say that,
I ∝ E^2
E = sqrt ( I )
E' = sqrt ( 2*I )
hence
E' = * E
so, the amplitude of the wave's electric field is times if the intensity of some electromagnetic wave doubles

Answer:
305.5°
Explanation:
1.76 = (theta/360) × 2 × pi × 0.33
theta/360 = 0.8488263632
theta = 305.5774907
Answer:
There are four natural states of matter: Solids, liquids, gases and plasma.
Explanation:
The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.
Answer:
See explanation
Explanation:
Heat is defined as a form of energy due to temperature difference. Heat is also a measure of the total internal energy of a body.
Heat has the following effects;
1) Heat causes change of state of a body
2) Heat changes the temperature of a body
3) Heat causes expansion of a body
4) Heat may alter certain physical properties of a body such as electrical conductivity, density etc
5) Heat causes a change in the pressure and volume of a body
6) Heat may lead to the emission of electrons from metals(thermionic emission)
Phagocytes are cells capable of engulfing and digesting particles or cells harmful to the body. They search for viruses and harmful bacteriae and engulf them. This way they stop disease from spreading. Phagocytes are part of our immune system whose main purpose is to keep us healthy.
