AnnyKZ [126]

Answer:

Voltage Drop Testing

Explanation:

The motives behind conducting Voltage Drop Testing is to recognize or identify the presence of unwanted resistance in the wire. or any other electrical appliance.  The appliance used to calculate the voltage drop is digital volt ohmmeters.  

voltage drop is the amount of loss of voltage due to resistance when electric current flow through the circuit. Thus measuring the voltage drop in respect to the amount of current flow, resistance can be measured.

The restoring force on a pendulum bob is proportional to sin(θ), where θ is the angle which the pendulum makes with the vertical
anyanavicka [17]

Answer:

The angle is 4.44º

Explanation:

If:

\frac{sin\theta -\theta}{\theta } \leq 0.1o/o\\\frac{sin\theta -\theta}{\theta }\leq 10^{-3}

According the Taylor`s series:

sin\theta =\theta -\frac{\theta ^{3}  }{3!}  ....

\frac{\theta ^{2} }{6} \leq 10^{-3} \\\theta ^{2} \leq 6x10^{-3} \\\theta \leq \sqrt{6x10^{-3} } \\\theta \leq 0.0775\\\theta = 0.0775rad=4.44

A crane exerts a net force of 900 N upward on a 750-kilogram car as the crane starts to lift the
Darya [45]

The acceleration of the car is 1.2 m/s^2 upward

Explanation:

We can solve the question by using Newton's Second Law of motion, which states that:

F=ma

where

F is the net force exerted on an object

m is the mass of the object

a is its acceleration

In this problem, we know that:

F = 900 N is the net force exerted on the car

m = 750 kg is the mass of the car

Solving the equation for a, we find the acceleration of the car:

a=\frac{F}{m}=\frac{900}{750}=1.2 m/s^2

and it is in the same direction as the force (upward).
