Your answer is C. hope this helped! :)
The reason why 1 kg of gas has a larger volume than 1 kg of a solid is because the molecules are spread father apart where a solids are much closer and cannot move freely
Given resistance in ohms and current in ampere, the power can be calculated by the equation,
P = I² x R
where I is current, P is power, and R is resistance
Substituting the given values,
1.00 x 10² = (I²) x 136 ohms ; I = 0.8575 amp
Then, by Ohm's law, the value of V = I x R. Substituting,
V = (0.8575 amp) x (136 ohms) = 116.619 volts
Thus, the potential difference across the lamp is approximately equal to 116.619 volts.
Answer:
v1 = v2
Explanation:
Given:
- The missing figure is (attached).
- The Magnetic Field B1 > B2
Find:
How does the speed v1 of the electron in region 1 compare with the speed v2 in region 2?
Solution:
- From Lorentz Law we know that the Force that acts on the charge particle is the cross product of Magnetic Field Vector ( B1 or B2 ) and the velocity vector (v1 or v1).
- From the attached figure related to this problem we see that the electron velocity or direction of motion is always parallel to the magnetic field B1&B2.
- The law of cross product for parallel vector is 0. Hence, the Lorentz force acting on the electron is also zero.
- Zero Force means no work is done on the particle by the magnetic field, thus, the change in kinetic energy also zero for conservation of energy to hold.
- The initial and final kinetic energies of the electron is same. Hence, we can conclude that v1 = v2.
