Although most magnetic reversing starters provide mechanical interlock protection, some circuits are provided with a secondary b

ioda

Answer:

To provide electrical interlocking

Explanation:

Electrical interlocking involves interconnecting the motor circuit in a manner that the second motor will not start until the first one begins, same goes for the third motor which would not run unless the second one runs and it continues in that sequence.

In your own words, describe the purpose of using a chemical equation.

Scilla [17]

Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.

A golf ball is hit with an initial velocity of 15 meters per second at an angle of 35 degrees above horizontal. What is the vert

polet [3.4K]

Answer:

8.6 m/s

Explanation:

The components of the initial velocity of the ball can be found by using the equations:

$v_x = v cos \theta\\v_y = v sin \theta$

where

$v_x$ is the horizontal component

$v_y$ is the vertical component

v is the magnitude of the velocity

$\theta$ is the angle above the horizontal

Substituting:

v = 15 m/s

$\theta=35^{\circ}$

We find:

$v_x = (15)(cos 35^{\circ})=12.3 m/s\\v_y = (15)(sin 35^{\circ})=8.6 m/s$

A charge of 1. 5 µC is placed on the plates of a parallel plate capacitor. The change in voltage across the plates is 36 V. How

ELEN [110]

It is a type capacitor is in which two metal plates arranged in such a way so that they are connected in parallel . The potential energy is stored in the capacitor will be 2.7×10⁻⁵.

<h3>What is parallel plate capacitor ?</h3>

It is an type capacitor is an in which two metal plates arranged in such a way so that they are connected in parallel and have some distance between them.

A dielectric medium is a must in between these plates. helps to stop the flow of electric current through it due to its non-conductive nature .

The given data in the problem is;

Q is the charge= 1.5 µC

V is the change in voltage across the plates is = 36 V.

U is the potential energy=?

The formula for the potential energy is given by;

$\rm U= \frac{1}{2} \times Q \times V \\\\ \rm U= \frac{1}{2} \times 1.5\times 10^{-6} \times 36 \\\\ \rm U=2.7\times10^{-5}$

Hence the potential energy is stored in the capacitor will be 2.7×10⁻⁵.
