Answer:
See the answer below
Explanation:
Newton's third law states that for every action, there will always be an opposing reaction of equal magnitude to the action.
<em>Hence, the wall will exert an equal opposing force to the head and the roommate will feel this opposing force as pains and/or headache. </em>
Explanation:
we know that,
linear speed = circumference × revolution per minute
linear speed of belt = 2πr × revolution per minute
now we will compute the linear speed of a belt for 2 inch pulley that is,
linear speed for 2 inch pulley = (2π×2)×( 3 revolutions per minute) ∵ r =2
= 4π × 3 revolution per minute (1)
again we will compute the linear speed of a belt for 8 inch pulley,
linear speed of 8 inch pulley = (2π×8) × (x revolution per minute) ∵ r =8
= 16π×x revolutions per minute (2)
As the linear speed is same for both pulleys. by comparing equations (1) and (2).
4π×3 = 16π×x
x = 3/4
Thus, the revolutions per minute for the 8 inch pulley is 3/4.

Answer: 25N
method: total force in the right hand direction is 100N and total force in the left hand direction is 125N. To get the net force, we add forces if they are in the same direction and substract if they are in opposite directions. since 100N and 125N are in opposite directions, we substract the larger value from the smaller value. Then we get 25N in the left hand direction as the final answer.
Answer:
(G) 75.11 ohm
(H) 0.08 A
(I) 46.2 degree
Explanation:
R = 52 ohm
L = 4.8 m H = 4.8 x 106-3 H
C = 330 nF = 330 x 10^-9 F
Vo = 6 V
(G)
f = 5000 Hz
Let the impedance is Z.
(H) Let Io be the peak current
(I) Let Ф be the phase angle
Ф = 46.2 degree
