Answer:
Explanation:
Given
radius of wheel 
mass of wheel 
Force 
Moment of Inertia of solid wheel 
Torque is given by
Force on the axle is 32 N since there is no linear acceleration of the system
using Third law F=32 N
Torque of the axle applied to the wheel is zero because force of axle imparted at the center of axle
Answer:
Explanation:
Given
Ray of light incident on plane making an angle of 
with normal
Thus incident angle 
So according to the law of incidence is equal to angle of reflection
thus 
and angle between mirror and reflected ray 
Answer:
0.056 psi more pressure is exerted by filled coat rack than an empty coat rack.
Explanation:
First we find the pressure exerted by the rack without coat. So, for that purpose, we use formula:
P₁ = F/A
where,
P₁ = Pressure exerted by empty rack = ?
F = Force exerted by empty rack = Weight of Empty Rack = 40 lb
A = Base Area = 452.4 in²
Therefore,
P₁ = 40 lb/452.4 in²
P₁ = 0.088 psi
Now, we calculate the pressure exerted by the rack along with the coat.
P₂ = F/A
where,
P₂ = Pressure exerted by rack filled with coats= ?
F = Force exerted by filled rack = Weight of Filled Rack = 65 lb
A = Base Area = 452.4 in²
Therefore,
P₂ = 65 lb/452.4 in²
P₂ = 0.144 psi
Now, the difference between both pressures is:
ΔP = P₂ - P₁
ΔP = 0.144 psi - 0.088 psi
<u>ΔP = 0.056 psi</u>
First, we have to calculate the normal forces on different surfaces.The normal force on the 4.00 kg, N1 = (4)(9.8) = 39.2 N. The normal force on the 10.0 kg, N2 = (14)(9.8) = 137.2 N. Looking at the 10.0 kg block, the static forces that counteract the pulling force equals the sum of the friction from the two surfaces. Fc = N1 * 0.80 + N2 * 0.80 = 141.12 N. Since the counter force is less than the pulling force, the blocks start to move and hence, kinetic frictions are considered.
Therefore, f1 = uk * N1 = (0.60)(39.2) = 23.52 N.
A circuit computes various types of Boolean operations. As in the question no specific circuit has been shown,so we have to know the fundamental logic operations.
Out of the various types of logic operations in Boolean algebra,the simple operations are- addition,subtractions,multiplications,division through logic gates.
Various logic or Boolean operations are NOT GATE,OR GATE ,AND GATE .
There are other operations also like NAND GATE,NOR GATE and XOR GATE etc
NOT gate is the simple logic gate which inverts one quantity.it makes 1[high] to 0[low] and vice versa.
OR gate gives 1 [high] when one of the input is 1 and low when all the inputs are low.
AND operation gives 1 when all the inputs are high and low when one of the input is low
NAND operation is AND gate followed by a NOT gate
NOR operation is the OR gate followed by a NOT gate.
Remembering these simple rules we can get the idea of the operations involved in the circuit. Each circuit has different symbols and gives different results.
