Answer:

The neutron is located in the nucleus of an atom

Explanation:

Atom contain proton , neutron and electron. The electron is found in the outer part of an atom. The electron revolves around the atom. It determines how atom of elements are bonded.

The neutron and proton determines the mass of an atom. The proton number plus the neutron number determines the mass number of an element. The proton and neutron are located in the nucleus of an atom. The proton is usually positively charged while the neutron is neutral.

The neutron is located in the nucleus of an atom and it is neutral. The picture below demonstrates the location of neutron in an atom

Suppose that in a lightning flash the potential difference between a cloud and the ground is 1.3×109 V and the quantity of charg

Georgia [21]

Answer:

A) ΔU = 3.9 × 10^(10) J

B) v = 8420.75 m/s

Explanation:

We are given;

Potential Difference; V = 1.3 × 10^(9) V

Charge; Q = 30 C

A) Formula for change in energy of transferred charge is given as;

ΔU = QV

Plugging in the relevant values gives;

ΔU = 30 × 1.3 × 10^(9)

ΔU = 3.9 × 10^(10) J

B) We are told that this energy gotten above is used to accelerate a 1100 kg car from rest.

This means that the initial potential energy will be equal to the final kinetic energy since all the potential energy will be converted to kinetic energy.

Thus;

P.E = K.E

ΔU = ½mv²

Where v is final velocity.

Plugging in the relevant values;

3.9 × 10^(10) = ½ × 1100 × v²

v² = [7.8 × 10^(8)]/11

v² = 70909090.9090909

v = √70909090.9090909

v = 8420.75 m/s

Five race cars speed toward the finish line at the Jasper County Speedway. The table lists each car’s speed in meters/second. If

nekit [7.7K]

We have: v = d/t
From the expression, we conclude speed is indirectly proportional to speed.
So, the car which will take longer time must have the smallest speed. Among all the options Car C has the smallest speed. So, it would be your answer.

In short, Your Answer would be Option C) Car C will take longer time than any other.

Hope this helps!

Suppose it takes a constant force a time of 6.0 seconds to slow a 2500 kg truck

erastovalidia [21]

Answer:

$3.3\cdot 10^3\:\mathrm{N}$

Explanation:

Impulse on an object is given by $\mathrm{[impulse]}=F\Delta t$ .

However, it's also given as change in momentum (impulse-momentum theorem).

Therefore, we can set the change in momentum equal to the former formula for impulse:

$\Delta p=F\Delta t$ .

Momentum is given by $p=mv$ . Because the truck's mass is maintained, only it's velocity is changing. Since the truck is being slowed from 26.0 m/s to 18.0 m/s, it's change in velocity is 8.0 m/s. Therefore, it's change in momentum is:

$p=2500\cdot 8.0=20,000\:\mathrm{kg\cdot m/s}$ .

Now we plug in our values and solve:

$\Delta p=F\Delta t,\\F=\frac{\Delta p}{\Delta t},\\F=\frac{20,000}{6}=\fbox{$3.3\cdot 10^3\:\mathrm{N}$}$ (two significant figures).

A train traveling at 27.5 m/s accelerates to 42.4 m/s over 75.0 s. What is the displacement of the train in this time period

Sergio [31]

Answer:

2621.25 meters

Explanation:

First, write down what we are given.

Initial velocity = 27.5 m/s

Final velocity = 42.4 m/s

Time = 75 seconds

We need to look at the kinematic equations and determine which one will be best. In this case, we need an equation with distance. I am going to use $v_{f}^{2} = v_{i}^{2} +2ad$ , but you can also use the other equation, $x = v_{o}t+\frac{1}{2}at^{2}$

We need to find acceleration. To find it, we need to use the formula for acceleration: $a = \frac{v_{f}-v_{i}}{t}$ . Plugging in values, $a = \frac{42.4-27.5}{75} = .199\ m/s^{2}$

Next, plug in what we know into the kinematics equation and solve for distance. $42.4^{2} = 27.5^{2} + 2(.199)(d)\\d = 2621.25\ meters$

The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.

<h3>What is a magnetic field?</h3>

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

I is the current = 6.50 A

B is the magnetic field=f 2.71 X 10⁻⁵ T

The force on the wire is;

$\rm F= BIL \\\\\ F=2.71 \times 10^{-5} \ T \times 6.50 \ A \times 1.50 \ m \\\\\ F=0.000264225 \ N$

Hence, the force on one of the wires will be 0.000264 N.
