Answer:
93.8 sec
Explanation:
it is given that tab has 350 gallon
we know that 1 gallon = 0.134 cubic foot
350 gallon = 350×0.134=46.9 cubic foot
the delivery pressure is 100 psi which is greater than 80 psi to operate machine
it is given that supply volume is 30 cubic foot per minute
= 
![time\ required\= [tex]\frac{46.9}{0.5}](https://tex.z-dn.net/?f=time%5C%20required%5C%3D%20%20%5Btex%5D%5Cfrac%7B46.9%7D%7B0.5%7D)

Answer:
Expression for output voltage = V = Vo sin wt
Explanation:
Amplitude of output voltage = Vo = 19 V
Frequency = f = 240 Hz
Now we know that
Angular frequency = w = 2 π (1 / T) = 2 π 240 = 480 π Hz
Expression for output voltage = V = Vo sin wt
Expression for output voltage = V = 19 (sin 480 π) t
Answer:
Normal force = 0.326N
Explanation:
Given that:
mass released from rest at C = 3.7 g = 3.7 × 10⁻³ kg
height of the mass = 1.1 m
radius = 0.2 m
acceleration due to gravity = 9.8 m/s²
We are to determine the normal force pressing on the track at A.
To to that;
Let consider the conservation of energy relation; which says:
mgh = mgr + 1/2 mv²
gh = gr + 1/2 v²
gh - gr = 1/2v²
g(h-r) = 1/2v²
v² = 2g(h-r)
However; the normal force will result to a centripetal force; as such, using the relation
N =mv²/r
replacing the value for v² = 2g(h-r) in the above relation; we have:
Normal force = 2mg(h-r)/r
Normal force = 2 × 3.7 × 10⁻³ × 9.8 ( 1.1 - 0.2 )/ 0.2
Normal force = 0.065268/0.2
Normal force = 0.32634 N
Normal force = 0.326N
A staircase what makes it a lever is another objects used to displace the force better
