Answer:
Mechanical advantage = 3
Explanation:
Given:
Weight = 300 N
Force load = 100 N
Find:
Mechanical advantage:
Computation:
Mechanical advantage = Weight/Force Load
Mechanical advantage = 300/100
Mechanical advantage = 3
Answer:
Inductor should be placed the circuit to raise its power factor.
Explanation:
Inductor:
- It is passive component that is used in most electrical circuits to store energy in the form of magnetic energy when electric current flows through it.
- It has the function of developing electromotive force in the direction that reduces fluctuation when a fluctuating current flows.
Capacitor:
- It is a device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other.
we know that,
Power factor:
cosα = R / Z
cosα = R^2/ (sqrt(R
To increase the power factor, denominator should decrease.
from the equation we can say that, the power factor is inversely proportional to X(L)
Hence X(L) should increase.
Therefore, an inductor is required to be connected.

Answer:
The answer is given in the attacted image.
The density is
Explanation:
The problem is asking to find the density of the object.
The density of an object is given by:
where
m is the mass of the object
V is its volume
For the object in this problem, we have:
m = 35 g (mass)
(volume)
Substituting , we find the density:
