Answer:
The values is
Explanation:
From the question we are told that
The slit distance is
The wavelength is
At the first half of the screen from the central maxima
The number of bright spot according to the condition for constructive interference is
For maximum number of spot
So
Now for the both sides plus the central maxima we have
substituting values
Explanation:
Given,
- m = 100 kg
- g = 10 N/kg¹
- h = 60 m
- t = 20 s
To Find:
a) Work done by the pump
b) Potential energy stored in the water
c)Power spent by the pump
d)Power rating of the pump.
Solution:
- a) Work done by the pump
We know that,
- f = 100 kg * 10N/kg
- d = 60 m
[The unit'll be joule since N×M = J]
- b) Potential energy stored in the water
- m = 100 kg
- g = 10N/kg
- h = 60
- same condition here as well, N×M = J
- c) Power of the Pump
- where P = Power; W = Work done & T = Time taken
- As we got the value of work done on question (a),& ATQ time taken is 20 S.
- d) Power rating of the pump = 3 kW
Assumption: The pump is 100% efficient & works well.
Answer:
The least number of forces required to stretch a spring is one.
Explanation:
Let suppose that spring is ideal, that is, that effects from its mass can be neglected since it is insignificant in comparison with external forces. In addition, let the spring have a linear behavior, meaning that net external longitudinal force exerted on spring is directly proportional to defomation. (Hooke's Law) That is:
(1)
(2)
Where:
- Net external force, measured in newtons.
- Spring constant, measured in newtons per meter.
- Deformation of spring, measured in meters.
Hence, the least number of forces required to stretch a spring is one.
