Answer:
L = 1.11 x m, is the length of piece of 20 cm wide Aluminum foil to make capacitor large enough to hold 52000 J of energy.
Explanation:
Solution:
Data Given:
Heat Energy = 52000 J
Dielectric Constant of the plastic Bag = 3.7 = K
Thickness = 2.6 x m =d
V = 610 volts
A = width x Length
width = 20 cm = 20 x m
Length = ?
So,
we know that,
U = 1/2 C Δ
U = 52000 J
C = ?
V = 610 volts'
So,
U = 1/2 C Δ
52000 J = (0.5) x (C) x ()
C = 0.28 F
And we also know that,
C =
E = 8.85 x
K = 3.7
A = 0.20 x L
d = 2.6 x m
Plugging in the values into the formula, we get:
0.28 =
Solving for L, we get:
L = 1.11 x m,
is the length of piece of 20 cm wide Aluminum foil to make capacitor large enough to hold 52000 J of energy.
Answer:
The correct statements are A and E.
Explanation:
This statements will be explained according to the Newton's third law of motion. It states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction (law of action and reaction).
A. You are experiencing a larger acceleration than your friend, but in the opposite direction. True. The forces are equal, but the mass of each individual is different, so the acceleration has to be different too. In this case, the smaller mass (you) has the large acceleration.
B. You are experiencing the same acceleration as your friend, but in the opposite direction. False. The forces are equal but the accelerations are different.
C. You are experiencing a smaller acceleration than your friend, but in the opposite direction. False. You are experiencing a larger acceleration due to the smaller mass.
D. You are experiencing a smaller force than your friend, but in the opposite direction. False. The forces are equal for both masses.
E. You are experiencing the same amount of force as your friend, but in the opposite direction. True.This is what the law states.
F. You are experiencing a larger force than your friend, but in the opposite direction. False. The forces are equal.

Answer:
(a)
(b)
Explanation:
mass, m = 2.3 kg
vx = 40 m/s
vy = 75 m/s
(a) Angular momentum is given by
Where, p is the linear momentum and r is the position vector about which the angular momentum is calculated.
Here,
So, the angular momentum
(b) Here,
We know
