or

P = 5 kW

So, the power output of the generator is 5 kW.

The study of heat transformation into other forms of energy is called

Answers

Answer:

Thermodynamics.

Explanation:

Thermodynamics can be defined as the study of heat transformation into other forms of energy.

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles.

Generally, when conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

In Thermodynamics, heat are generally transformed to various forms of energy such as light energy.

The Law of Conservation of Energy states that energy cannot be destroyed but can only be converted or transformed from one form to another. Therefore, the sum of the initial kinetic energy and potential energy is equal to the sum of the final kinetic energy and potential energy.

Mathematically, it is given by the formula;

Ki + Ui = Kf + Uf .......equation 1

Where;

Ki and Kf are the initial and final kinetic energy respectively.

Ui and Uf are the initial and final potential energy respectively.

Additionally, the Law of Conservation of Energy is another way to describe the First Law of Thermodynamics and it states that the change of the internal energy of a system is equal to the sum of work and heat spent on it.

Mathematically, the First Law of Thermodynamics is given by the formula;

ΔU = Q − W

Where;

ΔU represents the change in internal energy of a system.

Q represents the net heat transfer in and out of the system.

W represents the sum of work (net work) done on or by the system.

A basketball is shot by a player at a height of 2.0 m. The initial angle
was 53° above horizontal. At the highest point the ball was travelling 6
m/s. If he scored (the ball went through the rim that is 3.00 m above the
ground), what was the player’s horizontal distance from the basket?

Answers

Answer:

The answer is "8.28 m".

Explanation:  

[tex]\to u \cos 53^{\circ}=6 \ \text{therefore the horizontal velocity is constant alaways}\\\\\therefore[/tex]

[tex]u= \frac{6 \times 5}{3}= \frac{30}{3}= 10\ \frac{m}{s}\\\\[/tex]

In the projectfile when vertical displacement is 1 then 5 m comes at farther sides

Using  

[tex]S=ut-\frac{1}{2} gt^2\\\\1=u\sin 53^{\circ}\times t-5t^2\\\\1=8t-5t^2\\\\5t^2-8t+1=0\\\\ t=\frac{8\pm \sqrt{64-20}}{10} \\\\=\frac{8\pm 2\sqrt{11}}{10} \\\\t_2=\frac{8+2\sqrt{11}}{10} \\\\[/tex]

[tex]Distance=u \cos 53^{\circ}\times t_2\\\\[/tex]

               [tex]=6 \times \frac{8\pm 2\sqrt{11}}{10} \\\\=\frac{24\pm 6\sqrt{11}}{5} \\\\= 8.28 \ m[/tex]

An upright image which reduced in size 10 times occurred in a mirror. If the radius of
curvature of the mirror is 2 m, bow far is the object from the mirror?​

Answers

Answer:

-10/9 m

Explanation:

Radius of curvature, R=2 m

Focal length of mirror, f=R/2=2/2=1 m

Let height of object=h

Height of image, h'=h-10h=-9h

We have to find the distance of object from the mirror.

Magnification, m= [tex]\frac{h'}{h}=-\frac{v}{u}[/tex]

[tex]m=\frac{-9h}{h}=-9[/tex]

Image is upright and small in size it means the mirror is convex.

Focal length of convex mirror is negative.

f=-1m

[tex]-9=-\frac{v}{u}[/tex]

[tex]v=9u[/tex]

Now, mirror formula

[tex]\frac{1}{v}+\frac{1}{u}=-\frac{1}{f}[/tex]

[tex]\frac{1}{9u}+\frac{1}{u}=\frac{1}{1}[/tex]

[tex]\frac{1+9}{9u}=-1[/tex]

[tex]10=-9u[/tex]

[tex]u=-\frac{10}{9} m[/tex]

Hence, the distance of object  from the mirror is -10/9 m

A train covers 450 km in 5 hr. between Station A and Station B.
What is the average speed of train in km/h and m/s.

Answers

Answer:

90 km/h

50 m/s

Explanation:

Distance = 450 km

Time = 5hrs

Speed = Distance/Time

450/5 = 90 km/h

1 km = 1,000 m

1 hr = 60m = 60 x 60 = 3,600 sec

but since it's 5hrs = 60 x 300m = 18,000

90 x 1,000 = 90,000/18,000 = 50 m/s

If the density of a substance is 5g/cm3 and the volume is 10cm3,
determine the mass.

Answers

Answer:

(5g/cm³)*(10cm³) = 50g

Explanation:

This is just a conversion formula. Easy to find using dimensional analysis.

(5g/cm³)*(10cm³) = 50g

Answer:

[tex]\boxed {\boxed {\sf 50 \ grams}}[/tex]

Explanation:

Density is the amount of mass per unit volume, so the formula is:

[tex]d = \frac{m}{v}[/tex]

The density of the substance is 5 grams per cubic centimeter and the volume is 10 cubic centimeters.

d= 5 g/cm³ v= 10 cm³

Substitute the values into the formula.

[tex]5 g/cm^3 = \frac{m}{10 \ cm^3}[/tex]

We are solving for the mass, so we have to isolate the variable m. It is being divided by 10 cubic centimeters. The inverse of division is multiplication, so we multiply both sides of the equation by 10 cm³.

[tex]10 \ cm^3 *5 g/cm^3 = \frac{m}{10 \ cm^3} * 10 \ cm^3[/tex]

[tex]10 \ cm^3 *5 g/cm^3 = m[/tex]

The units of cubic centimeters (cm³) cancel.

[tex]10 *5 g = m[/tex]

[tex]50 \ g=m[/tex]

The mass of the substance is 50 grams.
