Potential energy, I’m pretty sure I don’t know but we was learning this in science and this is all I remember that potential energy is the moment energy reaches to a stop...
<span>What type of severe weather, direction the weather, any significant weather that may cause death or property destruction, and what areas will be affected by the severe weather is the information that is required for advance warnings of severe weather conditions. </span>
Answer:
a) , b) , c) , d)
Explanation:
b) The kinetic energy for a rigid body is the sum of translational and rotational kinetic energy:
The speed of the center of mass of the sphere at the initial position is:
a) The kinetic energy associated with the rotation is:
It is 40 % of the total initial kinetic energy.
c) The total final kinetic energy is:
d) The speed of its center of mass is:
Answer:
The shift in the emission spectra of the relative velocity between the star and our planet, is called the relativistic doppler effect
Explanation:
The absorption and emission spectra are measured differently, the emission spectrum is the spectrum emitted by the star and the absorption spectrum is the absorption of these lines by the gases of our atmosphere, this absorption occurs for relatively broad Δλ.
The shift in the emission spectra of the relative velocity between the star and our planet, is called the relativistic doppler effect and has a red shift if the star moves away from us.
The induced emf is 4.324 V.
It is given that the current in a 160 mH coil changes steadily from 22.0 A to 12.0 A in 370 ms.
We need to determine the magnitude of the induced emf.
An emf is induced in the coil when a bar magnet is pushed in and out of it.
The emf induced in a circuit is directly proportional to the time rate of change of the magnetic flux through the circuit.
Mathematically,
E=LdI/dt
Here
L = 160mH = 0.16H
I = 22A - 12A
dI = 10A
dt=0.37s
Putting values,
E=0.16*10/0.37
E=4.324 V.
