Answer:
<h2>the answer would be 0 as known to the length</h2>
Explanation:
0m x96 would put as an mass of 900 into 0 so there for your answer would be 0
Answer:
Yes, I agree with rich
Explanation:
Yes I agree with rich.
Thus is because;
The electromagnetic process is what will determine how electromagnetic radiation will be emitted. Now, the mode of travel of electromagnetic energy is in the form of waves and then the wavelength of these waves is what will enable us know the form of energy. This includes light, x-rays, gamma rays e.t.c. This means that light and the others are just parts of the spectrum emitted and are called photons.
Thus, light can be said to be electromagnetic radiation.
<h2>Answer:</h2>
Entropy is the reason of worrying about world energy sources.
<h3>Explanation:</h3>
- Entropy is the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
- The amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
- For example , There are some reactions which are irreversible because some of the energy in the reaction is lost to environment instead of converting totally to the products.
- This lost of energy is entropy.
- Due to which the energy of universe is losing irreversibly.
- That's why we worry about world energy sources.
Answer:
b) increase.
c) decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Explanation:
a ) Young's interference is the interference phenomenon related to the light waves. Interference is the superposition of light waves . It proved the wave nature of light . Interference can be either constructive or destructive.
b) If the distance between the two slits increases, the number of fringes also increases. d sinθ = m λ. Here d is the slit width and m is the order of fringes. It shows that as d increases, m also increases.
c) Similarly, as d decreases , number of fringes decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Answer:
Mechanical energy = 35 Joules
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Potential energy (P.E): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (K.E): it is an energy possessed by an object or body due to its motion.
Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.
Mathematically, it is given by the formula;
Mechanical energy = P.E + K.E
Given the following data;
Potential energy = 15 J
Kinetic energy = 20 J
To find the mechanical energy;
Mechanical energy = P.E + K.E
Mechanical energy = 15 + 20
Mechanical energy = 35 Joules
