Answer:
MT disc I = 2,752 10-3 kg m²
MB disc I = 2,726 10⁻³ kg m²
Explanation:
The moment of inertia given by the expression
I = ∫ r² dm
for bodies with high symmetry it is tabulated
for a hollow disk it is
I = ½ M (R₁² + R₂²)
let's apply this equation to our case
disc MT = 1,357 kg
I = ½ 1,357 (0.0079² + 0.0632²)
I = 2,752 10-3 kg m²
disk MB = 1,344 kg
I = ½ 1,344 (0.0079² + 0.0632²)
I = 2,726 10⁻³ kg m²
Answer:
The correct answer is B. <u><em>Strong Nuclear.</em></u>
Explanation:
An atom contains protons, neutrons, and electrons. The nucleus of an atom consists of bound protons and neutrons (nucleons). The negatively charged electrons are attracted to the positively charged protons and fall around the nucleus, much like a satellite is attracted to the gravity of the Earth. The positively-charged protons repel each other and aren't electrically attracted or repelled to the neutral neutrons, so you may wonder how the atomic nucleus sticks together and why protons don't fly off.
The explanation for why protons and neutrons stick together is known as "the strong force." The strong force is also known as the strong interaction, color force, or strong nuclear force. The strong force is <u><em>much more powerful</em></u> than the electrical repulsion between protons, however, the particles have to be close to each other for it to stick them together.
Answer: 12.12 m
Explanation:
We have the following data:
is the speed of the water wave
is the frequency of the water wave
Now, the speed of a wave is given by the following equation:
Where is the wavelength.
Isolating :
Finally:
This is the water wave wavelength
a.) Relative velocity = velocity of car B - velocity of car A
= 19 - 14
= 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)
The kinetic energy of the person would be 1062.5J
<u>Explanation:</u>
Given:
Mass of the person, m = 85kg
Velocity, v = 5m/s
Kinetic energy, KE = ?
We know,
Substituting the value in the equation:
Therefore, the kinetic energy of the person would be 1062.5J
