electromagnetic force, and the number of nucleons involved in the fusion in your answer.

Help me on thiss one once again ughh ! asap ! hurry

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.

12 rev per 4 seconds

3 rev per second

180 rev per minute

18.8 rad per second

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.**

** **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?

**Answer:**

76.53 kg; 9.15 m/s² left.

**Explanation:**

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]

Where;

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. **

**Explanation:**

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

Answer:

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

Explanation:

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.

What type of glass is heat resistant?

A.leaded glass

B.tinted glass

C.borosilicate glass

D.tempered glass

**Answer:**

D.

**Explanation:**

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?

Choices:

•200.0m

•100.0m

•1000.0m

•25.0m

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

and given:

d=?

Vi= 0 m/s

Vf=?

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

and given:

d=?

Vi= 0 m/s

Vf=?

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

seconds)?

**Answer:**

7.28 s

**Explanation:**

s=-260

u=0

assume a=-9.81

t=?

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**

whats the order of solid liquid and gas from least particle motion to the most?

**Answer:**

Solid < Liquid < Gas

velocity is derived physical quantity why

**Answer:**

Velocity is “how much distance you cover in a particular time.” Space and time are fundamental quantities, and meters and seconds are their base units. Velocity is a combination of a space and a time, and therefore its units — “m/s” – are “derived” from the units for space and time

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**

**Explanation:**

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.

Atlantic Video, a small video rental store in Philadelphia, is open 24 hours a day, and-due to its proximity to a major business school-experiences customers arriving around the clock. A recent analysis done by the store manager indicates that there are 30 customers arriving every hour, with a standard deviation of interarrival times of 2 minutes. This arrival pattern is consistent and is independent of the time of day. The checkout is currently operated by one employee, who needs on average 1.7 minutes to check out a customer. The standard deviation of this check-out time is 3 minutes, primarily as a result of customers taking home different numbers of videos.Required:a. If you assume that every customer rents at least one video (i.e., has to go to the checkout), what is the average time a customer has to wait in line before getting served by the checkout employee (i.e., waiting time in queue)?b. If there are no customers requiring checkout, the employee is sorting returned videos, of which there are always plenty waiting to be sorted. How many videos can the employee sort over an 8-hour shift (assume no breaks) if it takes exactly 1.5 minutes to sort a single video?c.
