The answer is a. the rotor
Answer:
<621, 0 , 0>
Explanation:
given,
mass of the car ,m = 1425 Kg
location of car = < 266, 0, 0 > m
momentum of the car = < 46000, 0, 0 > kg.m/s
M v_x = 46000
1425 x v_x = 46000
v_x = 32.28 m/s
v_y = 0 m/s
v_z = 0 m/s
Location of the car after 11 s
x = v_x t + 266
x = 32.28 x 11 + 266
x = 621 m
hence, the location of car after 11 s is equal to <621, 0 , 0>
Answer: D
Explanation: Look at the figure, we can conclude that the correct answer is
X: Low potential energy
Y: High potential energy
Z: Flow of electrons
Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.
Since the arrow is pointing to X, that means
Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.
Answer:
Explanation:
Given
Mass of particle is
Charge of particle is
Electrostatic force must balance the weight of the particle
Direction of the electric field is in upward direction such that it opposes the gravity force.
