Answer:
The individual positive plate capacity is 85 Ah.
(D) is correct option.
Explanation:
Given that,
Number of plates = 15
Capacity = 595 Ah
We need to calculate the individual positive plate capacity in motive power cell
We have,
15 plates means 7 will make pair of positive and negative.
So, there are 7 positive cells individually.
The capacity will be
Put the value into the formula
Hence, The individual positive plate capacity is 85 Ah.
Answer:
7200N
Explanation:
Centripetal force is directly proportional to the product of the mass and the square of the velocity and inversely proportional to the radius given.
Answer:
(a) the height in the open water column is: 18.15 (ft), (b) the gauge pressure acting on the bottom tank surface AB is: 8.73 (Psi) and (c) the absolute pressure of the air in the top of the tank with local atmospheric pressure at 14.7 Psi will be: 21.7 (Psi).
Explanation:
We need to apply the Pascal's Law, () where P is pressure, γ is the specific weight of the fluid and h is the height of the column of fluid, to find the pressure at differents points in the tank (see attached). First we need to assume a property of the water called specific weight as: 62.4 (lbf/ft^3) or 0.03612 (lbf/in^3). Then knowing that 1 feet as the same as 12 inches and appling Pascal's Law, we get: and the other hand, we have: and knowing that the pressure at point C and point D are the same, we can find the h as:, so getting h=217.75(in) or 18.15(ft) (a). Now similarly to find the gauge pressure acting on the bottom of the tank surface AB we can apply Pascal's Law as: (b). Finally we can find the absolute pressure of the air in the top of the tank, assuming a local atmospheric pressure as 14.7 (Psi) so: (c).
We know follwing formula
F=a*m
where F is RESULTANT force, a is acceleration and m is mass. We can transform that formula to obtain a, so
F=a*m /:m divide both sides by m
Now we have to calculate resultant force acting.
We know that Dale and Alex push on opposite direction so we have to put minus in front on one of the forces and add it.
40+(-32)=40-32=8 [N] - resultant force acting on the couch
Now we have all necessary date, we can substitute.
a=
- its the result
