Are there answers choice or a picture I can see?
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.
Since the acceleration is uniform, we can calculate it from the data we are given:
a = (vf - vi)/2
where vf=33 m/s and vi=11 m/s
Then use Suvat's equation:
x(t) = vi*t + 0.5 * a * t
where t=20s
Answer:
When an object moves in a straight line, it is said to be in linear motion. By Newton's first law of motion, a body tends to be in rest or motion in a straight line until a net non-zero force acts on it.
Rate of change of position with respect to time is known as velocity. Uniformly accelerated motion refers to the motion where the rate of change of velocity with respect to time is constant.
Kinematic equations can be used to measure different aspects of a linear motion:
v = u + a t
s = u t + 0.5 a t²
v²= u² + 2 a s
where, u is initial velocity, v is final velocity, a is acceleration, t is time and s is displacement.
The initial speed of the sled at the given height is 4.85 m/s.
<h3>Initial speed of the sled</h3>
Apply the principle of conservation of energy;
K.E = P.E
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is the vertical height reached
- g is acceleration due to gravity
v = √(2 x 9.8 x 1.2)
v = 4.85 m/s
Thus, the initial speed of the sled at the given height is 4.85 m/s.
