<span>Torque = force * distance from axis of rotation. Multiply.
If it's not perpendicular, you multiply that with the sine of the angle between the force and the perpendicular direction.
T= 0.470*57*Sin 90 = 26.79 N</span>
Answer:
V = (-32t +32) ft/s
The velocity of the bowling ball after t seconds is the time derivative of the position function s(t). To obtain the velocity from s(t) we simply differentiate s(t) with respect to t. That is
V = ds(t)/dt = -16×2t + 32×1 = -32t + 32.
When differentiating, you multiply the coefficient of each term in the equation with the power of the variable and then reduce the power by 1 just like above.
Explanation:
Answer:
B.The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.
Explanation:
As we know that the small gear completes 24 revolutions in 20 seconds
so the angular speed of the smaller gear is given as


Now we know that the tangential speed of the chain is given as

so we have



Since both gears are connected by same chain so both have same linear speed and hence correct answer will be
B.The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.
Answer:
The intensity is 
Explanation:
From the question we are told that
The intensity of the unpolarized light is 
The angle between the ideal polarizing sheet is 
Generally the intensity of light emerging from the first polarizer is mathematically represented as

substituting values


Then the intensity of incident light emerging from the second polarizer is mathematically represented by Malus law as

substituting values
![I_2 = 2000 * [cos (24.58)]^2](https://tex.z-dn.net/?f=I_2%20%20%3D%202000%20%20%2A%20%5Bcos%20%2824.58%29%5D%5E2)
