Calculate the number of neutrons. Now you know that atomic number = number of protons, and mass number = number of protons + number of neutrons. To find the number of neutrons in an element, subtract the atomic number from the mass number.
<u>Complete Question:</u>
Which of the following electromagnetic waves carries the highest energy, and are most damaging to human?
A. Gamma Rays
B. Microwave
C. Radio-wave
D. Alpha Rays
<u>Correct Option:</u>
Gamma Rays carries the highest energy, and are most damaging to human.
<u>Option: A</u>
<u>Explanation:</u>
The waves of light and other forms of energy that radiate or travel from where they are originated is understood as electromagnetic radiation, and collectively represent electromagnetic spectrum. The gamma rays are dangerous sources of radiation with high energy. Its standard size is 0.000001 nm i.e. size of atomic nucleus diameter. It results from the degradation of atomic nuclei by radioactive means. It is made up of the smallest electromagnetic wavelength, and thus provides the highest photon energy.
Answer:
Momentum
Explanation:
Truck A has a greater momentum compared to Truck B.
Momentum is the product of mass and velocity of a body;
Momentum = mass x velocity
We see that the body with more mass and velocity will have a higher momentum.
Since the two bodies have the same mass, and the speed A is greater, then A will have a greater momentum.
Answer:
a
because the mechanical wave is when it goes over and over again
