12. Describe Binding energy and how it plays a role in nuclear fusion up to 56Fe (the synthesis of iron
nuclei). Include a description of the relationship between the strong nuclear force, the
electromagnetic force, and the number of nucleons involved in the fusion in your answer.
Help me on thiss one once again ughh ! asap ! hurry


Answer 1
The binding energy per nucleon increases in value from Hydrogen up to Iron (Fe 56). This causes lighter nuclei to fuse together to make more stable heavier nuclei.

The strong nuclear force is responsible for causing the fusion of the nuclei and it is much much stronger than the electromagnetic force that would otherwise keep the positive protons apart.

A rotating pulley completes 12 rev in 4 secs determine the average angular velocity in rev /s, rpm and in rad/s​


12 rev per 4 seconds
3 rev per second
180 rev per minute
18.8 rad per second

Answer: The average angular velocity  for a rotating pulley is 3 rev/s, 180 rpm, 6π rad/s.

The pulley turns rotating when the rope tugged and completes 12 rev in 4 seconds.

How to determine the average angular velocity?

 If we consider a pulley rotating in a same axis, every point in the pulley has the same angular velocity.

Formula for angular velocity:

                    ω = Δθ / Δt

The average angular velocity can be defined as the ratio of the angular displacement to the time.

                                θ = 12 rev, t = 4s

             1 revolution = 2π rad

It can be solved as:

      Revolutions / second: 

      rev / s = 12 / 4      

                  =  3

      Revolutions per minute:

        rpm   =  ( 12/4) × 60

                  =   180

      Radian / second :

        rad/s  =   (12×2π / 4 )

Dan steps on the brakes in his toy car which causes a braking force of 700 N to the left.
a) If Dan’s car weighs 750 N, then what is the mass of Dan’s car?
b) What is the acceleration of Dan’s car?



76.53 kg; 9.15 m/s² left.


Given the following data;

Weight of car = 750N

Applied force = 700N

a) To find mass

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, [tex] Weight, W = mg[/tex]

We know acceleration due to gravity is equal to 9.8 m/s²

Substituting into the equation;

[tex] 750 = m*9.8[/tex]

[tex]Mass, m = \frac{750}{9.8}[/tex]

Mass, m = 76.53kg

b) To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]


F represents force.m represents the mass of an object.a represents acceleration.

Making acceleration (a) the subject, we have;

[tex]Acceleration (a) = \frac{F}{m}[/tex]

Substituting into the equation;

[tex]Acceleration (a) = \frac{700}{76.53}[/tex]

Acceleration (a) = 9.15 m/s² left.

When a body like earth is moving in a circular path the work done in that case is zero because: (a) Centripetal force acts in the direction of motion of the body (b) Centripetal force acts along the radius of circular path (c) Gravitational force acts along the radius of circular path (d) Centrifugal force acts perpendicular to the radius of circular path



(b) Centripetal force acts along the radius of circular path


Centripetal force is a force experienced by a body moving in a circular path. It is expressed mathematically ad F = mv²/r

m is the mass of the body

v is the velocity

r is the radius of the circular path

When a body moves in a circular path, work dome is zero because Centripetal force acts along the radius of circular path and the force is at right angle with the motion of body.

Therefore, there are 24 atoms in the following chemical formula.

What type of glass is heat resistant?

A.leaded glass
B.tinted glass
C.borosilicate glass
D.tempered glass





Tempered glass is the less expensive alternative, and is best for lower temperature applications. It can withstand constant temperatures of up to 470 degrees F. Tempered glass is regular glass that has been strengthened through a thermal or chemical treatment. Tempering not only strengthens the glass but also changes its breakage pattern, causing it to shatter into small pieces instead of large sharp angles, reducing the chance of injury. It is best used for applications where the fire will not be near the glass, as constant temperatures of 500 degrees or more will cause it to weaken and shatter.

An object on another planet with g = 25 m/s^2 hits the ground from rest in 4 seconds. How far did it fall?



Using the kinematics equations Vf=Vi+ (a)(t) and d=Vi(t)+1/2(a)(t)^2
and given:

Vi= 0 m/s
g= 25m/s^2 (so a= 25m/s^2)
t= 4sec

you first have to use Vf=Vi+ (a)(t) to solve for Vf:

Vf= (0m/s) + (25m/s^2)(4 sec)
Vf= 100m/s

Now using d=Vi(t)+1/2(a)(t)^2

d= 0m/s +1/2(25m/s^2)(4)^2

Which gives us d= 200.0 meters

An apple is dropped from a 260m high building. How long will it take to hit the ground in



7.28 s




assume a=-9.81


s=1/2at^2 + ut

-260=1/2 (-9.81) t^2 +0t

t=7.28 s

The time taken for the apple to hit the ground from the high building is 7.28s.

Given the data in the question;

Before the apple was dropped, it was initially at rest, so

Initial velocity; [tex]u = 0 m/s[/tex]Distance or height from which it was dropped from; [tex]s = 260m[/tex]


To find the time it will take for the apple to hit the ground

We use the Second Equation of Motion:

[tex]s = u^2 + \frac{1}{2}at^2[/tex]

Where s is the distance or height from which it was dropped, u is its initial velocity, t is time and a is the acceleration due to gravity.

We know that earth's gravitational field or acceleration due to gravity; [tex]g = 9.8m/s^2[/tex]

Since the apple is falling, it under gravity; [tex]a = g = 9.8m/s^2[/tex]

We substitute our values into the equation and find t

[tex]260m = (0m/s)^2 + (\frac{1}{2} \ *\ 9.8m/s^2\ *\ t^2 )\\\\260m = 4.9m/s^2 \ * \ t^2\\\\t^2 = \frac{260m}{4.9m/s^2}\\\\t^2 = 53.06^2\\\\t = \sqrt{53.06s^2} \\\\t = 7.28s[/tex]

Therefore, the time taken for the apple to hit the ground from the high building is 7.28s

A car increases its speed while turning to the left.
A car decreases its speed while driving straight ahead.
A car maintains a constant speed while turning to the right.
A car maintains a constant speed while driving straight ahead.



B is the right answer


It is decreasing.

A car maintains a constant speed while driving straight ahead.

What is acceleration?

The acceleration of an object is the rate of change of velocity with time. It is measured in meter per second square.

Velocity of the car

The car undergoes velocity when there is change in direction of the speed.

Thus, the only option that does not describe acceleration is a car maintains a constant speed while driving straight ahead.

A 1500 kg car traveling at 15m/s to the south collides with a 4500 kg truck that is initially at rest at a stoplight. the car and truck stick together and move together after the collision, what is the final velocity of the two vehicles


Answer: 3.75 m/s


Here's what you know: The car has mass 1500 kg, and initial velocity 15.0 m/s.  The truck has mass 4500 kg and initial velocity 0 m/s.  The final mass is 6000 kg (4500 kg plus 1500 kg, because they stick together) and we are looking for the final velocity.  Using the formula p = mv, and the concept that p before equals p after, the p of the car plus p of the truck equals the p of them together. So, 1500 x 15 + 4500 x 0 = 6000 x v final.  22500 = 6000 v, and v = 3.75 m/s.  The velocity is positive, and the initial velocity of the car was positive, so the two vehicles together are traveling to the south just like the car was initially.
