Explanation:
System of forces in balance
ΣFy = 0 Equation (1)
Forces acting on the board
T₁: Tension in the left chain , vertical and upward
T₂ = 250 N : Tension in the right chain , vertical and upward
W₁ = 125 N : Weight of the board , vertical and downward
W₂ = 500 N : Weight of the person , vertical and downward
Calculation of the T₁
We apply the Equation (1)
ΣFy = 0
T₁+T₂-W₁-W₂ = 0
T₁ = -T₂+W₁+W₂
T₁ = -250 N+ 125 N+ 500 N
T₁ = 375 N
Most of the mass is located in the nucleus as suggested by Rutherford's gold foil experiment.
Answer:
The average linear velocity (inches/second) of the golf club is 136.01 inches/second
Explanation:
Given;
length of the club, L = 29 inches
rotation angle, θ = 215⁰
time of motion, t = 0.8 s
The angular speed of the club is calculated as follows;

The average linear velocity (inches/second) of the golf club is calculated as;
v = ωr
v = 4.69 rad/s x 29 inches
v = 136.01 inches/second
Therefore, the average linear velocity (inches/second) of the golf club is 136.01 inches/second
Answer:
Explanation:
The magnetic field due to straight wire is into the square coil.
As the current in straight wire decreases the magnetic flux in the coil decreases
. The induced magnetic field is into the coil.The induced current is along +y direction
