Select the correct answer.
Marianna [84]

Answer:

A

Explanation:

According to Newton's second law, acceleration is directly proportional to the net force. As the acceleration increases (when mass is constant), the net force increases. This is represented in the following formula.

f = ma

a =  \frac{f}{m}

a = acceleration

f = force

m = mass

Can someone please explain how to solve for impulse if momentum is not given, only mass and velocity are given
Marta_Voda [28]
You're in luck !  Momentum is the product of (mass) times (velocity). 

So if you're given mass and velocity, simply multiply them, and voila,
you have the momentum.

A flat circular coil having a diameter of 25 cm is to produce a magnetic field at its center of magnitude, 1.0 mT. If the coil h
tresset_1 [31]

Answer:

The current pass through the coil is 6.25 A

Explanation:

Given that,

Diameter = 25 cm

Magnetic field = 1.0 mT

Number of turns = 100

We need to calculate the current

Using the formula of magnetic field

B =\dfrac{\mu_{0}NI}{2\pi r}

I=\dfrac{B\times2\pi r}{\mu N}

Where, N = number of turns

r = radius

I = current

Put the value into the formula

I=\dfrac{1.0\times10^{-3}\times2\pi\times12.5\times10^{-2}}{4\pi\times10^{-7}100}

I=6.25\ A

Hence, The current passes through the coil is 6.25 A
