We are given
the torque requirement of 97 Newton meter.
The formula of the torque is
τ = r * F * sinθ
where
τ is the torque
r = radius from the axis of rotation to the point of application.
F = force exerted
θ = the angle between the lever arm and the radius
Try to substitute the given and solve for F.
Answer:
P = 100 lb
Explanation:
For an ideal machine:
where,
P = Effort = Input Force = ?
L = Effort Arm = Length of inclined plane = 10 ft
W = Load to be lifted = 200 lb
H = Load Arm = Height = 5 ft
Therefore,
<u>P = 100 lb</u>
It shows deflection for the presence of current.However it can't be used for the A.C. current used at home.hope this helped.
Answer:
Option B
Explanation:
The electrons flow from negative terminal of a battery to the positive terminal because as the charge of electron is negative, it will get repelled by the negative terminal of the battery
Conventional flow actually assumes that the current flows out of the positive terminal, through the circuit and into the negative terminal of the battery
It actually says that direction of flow of current is in opposite direction to the direction of flow of electrons
The direction of current will not change even a resistor is placed in the circuit and it generates a potential difference across the resistor
But the current tries to move in such a way in which there will be less resistance to the flow
Conservation of momentum so the total initial momentum in the system is equal to the total final momentum in the system. You must remember that if an object is travelling in the negative direction, you must put a negative sign for the velocity.
mv + mv = mv
plug in all the numbers
(0.0323)(4.50) + (0.078)(-1.12) = (0.0323 + 0.078)Vf
multiply everything together
0.14535 - 0.08736 = 0.1103Vf
simplify
0.05799 = 0.1103Vf
isolate for vf
Vf = 0.5257m/s east
