Answer:

The force acting on a body is always equal to the product of the mass of the body and its acceleration.

Explanation:

The force of a body is defined as the product of mass and acceleration of the body.

According to Newton's second law, wherever there is a change in momentum of the body for an interval of time, there is a force acting on it.

F = (mv - mu) / t

= m (v -u) /t

= m a

Where,

(v - u)/t - is the change in velocity of the body in the interval of time. It is equal to the acceleration of the body.

Hence, the equation for the force for any body becomes, F = m x a

A wire carries a steady current of 2.60 A. A straight section of the wire is 0.750 m long and lies along the x axis within a uni

ad-work [718]

Answer:

The magnetic force on the section of wire is $-2.925\hat{j}\ N$ .

Explanation:

Given that,

Current $I = 2.60\hat{i}\ A$

Length = 0.750 m

Magnetic field $B = 1.50\hat{k}\ T$

We need to calculate the magnetic force on the section of wire

Using formula of magnetic force

$\vec{F}=l\vec{I}\times\vec{B}$

$\vec{F}=0.750\times2.60\hat{i}\times1.50\hat{k}$

Since, $\hat{i}\times\hat{k}=-\hat{j}$

$\vec{F}=-2.925\hat{j}\ N$

Hence, The magnetic force on the section of wire is $-2.925\hat{j}\ N$ .

A light bulb operating at a voltage of 120 v has a resistance of 200 ω. what is the power?

cluponka [151]

The correct is 72 watt

We know that formula of power is $P=\frac{v^{2} }{r}$

so putting the value of Voltage and Resistance in Formula of power so we get

$P=\frac{120^{2} }{200} =72$

What is Power?

Electric power is the rate at which an electric circuit transfers electrical energy per unit time.

Typically, electricity is generated by generators, but it can also be supplied by sources such as electric batteries. The electric power industry typically distributes it via an electric power grid to businesses and homes (as domestic mains electricity).

Transmission lines allow electric power to be delivered over long distances and used for high-efficiency applications such as motion, light, or heat. Electric charges are converted to other forms of energy when they pass through an electric potential difference (voltage).

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? (Formula: )

Furkat [3]

KE = 1/2 * m * v2

We have to rearrange this so the subject is mass. (because the question asks for the mass of the object) :

Mass = (2 * KE) / v

Now input the values into this equation to get your answer :

Mass = (2 * KE) / v
Mass = (2 * 480) / 8
Mass = 960 / 8
Mass = 120
