Answer:

A) True

C)True

D)True

Explanation:

As we know that power is the rate at which work is done.

We know that mechanical work w given as

 w = ∫F.ds

F=Force

ds = Elemental displacement

So power P = F.V

V=Velocity

F=Force

The unit of power in SI unit is Watt or joule per second (J/s).But on the other hand the unit of power in English system is horsepower.

The is also can be defined as the rate at which energy is transformed.

Following option are corrects

A) True

C)True

D)True

docker41 [41]

The value of Q will be -8 C.

In the presence of an electric or magnetic field, matter experiences a force due to its electric charge.

A moving electric charge generates a magnetic field, and an electric charge has an accompanying electric field.

The information provided in the issue is;

The separation between and is 2m.

The separation between and is 2m.

An origin charge equals +2 C

The electric fields are identical in magnitude but are facing in different directions. As a result, the following relationship can be used

Q/16=1/2

The value of Q will be -8 C.

2. A 75 kg runner accelerates from 0.00 m/s to 10.0 m/s in 1.5 seconds.
raketka [301]
A :-) A.a.) Given - u = 0.00 m/s
v = 10.0 m/s
t = 1.5 sec
m = 75 kg
Solution -
a = v - u by t
a = 10 - 0 by 1.5
a = 10 by 1.5
a = 6.6 m/s^2

A.b.) sorry ! I don’t no how to do this question

The alternating current which crosses an apparatus of 600 W has a maximum value of 2.5 A. What is efficient voltage between its
azamat

Answer: Option (b) is correct.

Explanation:

Since we know that,

P = VI

where;

P = power

V= Voltage

I = Current

Since it's given that,

P = 600W

I = 2.5 A

equating these values in the above equation, we get;

<em>V = \frac{600}{2.5}</em>

<em>V = 240 V</em>
