False. Most of the bright stars in our galaxy are located in the disk.
Answer:
Noise in the environment
Electrons emitted via the photoelectric effect
Explanation:
Physical entropy can be seen as a disorderliness that can be observed in a physical system. The noise in a physical system can be used for secure number generation because of its randomness.
Noise is known to have no defined pattern and hence, can be used to creates secure random key generations.
Electrons emitted via the photoelectric effect: Electrons are emitted in a random order whenever a beam of light is incident on a photoelectric material. These electrons emitted can be used for random key generations
Answer:
For objects at rest, we can use the equation of:
E = mc^2 to obtain the energy of the object
where E is energt, m is mass and c is the speed of light.
Then, the mass of the wood or metal blocks is related to the energy by that equation.
If we are talking about other energies, like kinetic energy, it can be written as:
K = (m/2)*v^2
So again, the mass is related to the energy, more mass implies more energy.
Answer:
70.6N
Explanation:
We are given that
Mass of crate=12 kg
Coefficient of static friction=[tex\mu=[/tex]0.40
Horizontal component force is equal to friction force
Force along vertical direction
..(2)
Using equation(2) in equation (1)
Substitute the values then we get
Hence, the minimum force needed to start the crate moving=70.6N
