yes could the half of the moon that faces the earth ever be completely dark

The moon is the captivating celestial body that can be observed through eyes, it is the biggest heavenly body in the night sky which changes its shape constantly.

The waning and waxing of moon cause the changes in face of the moon. The waning and waxing of the moon is directly related to the rotation of the moon.

The rotation of the moon is an extraordinary occurrence as the time the moon takes for completely orbiting the earth is exactly the time it takes to rotate once on its own axis.

Both the actions take 27.3 days to complete. This is unique feature of the moon is rare when compared to other celestial bodies. The energy given to the moon comes from Earth's rotation and to compensate, our planet is slowing down.

Answer:

L = 1.61 cm

Explanation:

The frequency of open organ pipe is given by :

[tex]f=\dfrac{nv}{2L}[/tex]

Where

n = 1 for fundamental frequency

f = 10500 Hz

L is the length of the pipe

v is the speed of sound, v = 340 m/s

So,

[tex]L=\dfrac{nv}{2f}\\\\L=\dfrac{1\times 340}{2\times 10500 }\\\\L=0.0161\ m\\\\or\\\\L=1.61\ cm[/tex]

So, the length of the pipe is 1.61 cm.

Remark

This is a second class lever. It is much more efficient than the fishing pole problem. All distances are measured from the pivot in these kinds of questions.

Givens

d1 = 1.5

d2 = ?

m1 = 50 kg

m2 = 30 kg

The lighter child will have to sit further away from the pivot to make the two conditions equal.

Formula

d1*m1 = d2*m2

1.5*50 = d2 * 30

75 = 30 * d2

75/30 = d2

d2 = 2.5

Remark

Notice that the distance is longer for the lighter child. The fact that these are masses and not forces does not matter, but you should take note of it. There is a difference between masses and forces. See the fishing pole problem.

Answer to the multiple Choice question. No motion on this kind of problem means equal moments. The answer is D

Problem 2

1) The wheels are further apart making B more stable. The wider the distance the wheels are apart, the harder it would be to tip the concrete mixer over

2) The center of gravity is lower. The higher the force is the more chance you have of exerting an external force to tip the mixer over.

Answer:

1000kg

Explanation:

We can use the equation "p=mv"

If we rearrange the equation to find mass (m), then the equation becomes:

m=p/v

We can substitute in the values of p and v as they are already given in the question.

So, now we just substitute in the values to get our answer.

m=p/v

m=25,000/25

m=1000kg

Answer:

Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects, and is inversely proportional to the square of the distance between them. The factors G, M, and r are the same for all masses at the surface of the Earth.

[tex]a=4.03\ m/s^2[/tex]

Explanation:

Given that,

The mass of the motorbike and rider is 286 kg.

We need to find the acceleration of the motorbike at this moment in time.

Net force acting on the bike is given by :

F = 2000 N - 845 N = 1155 N

Let a be the acceleration of the motorbike. So,

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{1155}{286}\\\\a=4.03\ m/s^2[/tex]

So, the acceleration of the motorbike is [tex]4.03\ m/s^2[/tex].

Explanation:

back ground radiation is a natural radiation so basically everything emits background radiation. so if it were harmful, the world wouldn't be here,

so it is false

it knocks electrons out of atoms, this is because ionising radiation is a radiation that had enough energy to remove electrons form the atoms and molecules.

true because exposure to radon can damage biological molecules such as proteins, which leads to abnormal patterns of cell division, which leads to cancer.

Answer:

The momentum of bike is more.

Explanation:

Given that,

Mass of the kid, m = 100 kg

Speed of the bike, v = 10 m/s

The momentum of the kid is given by :

p = mv

So,

p = 100 kg × 10 m/s

p = 1000 kg-m/s

Mass of the truck, m = 5000 kg

Speed of the truck, v = 0.1 m/s

The momentum of the truck is given by :

p = 5000 kg × 0.1 m/s

= 500 kg-m/s

So, the momentum of the kid riding a bike is more than that of the truck.

Answer:

10m/s^2

Explanation:

Given data

velocity= 40m/s

time= 4 seconds

Acceleration a =????

We know that

a= velocity/time

substitute

a=40/4

a= 10m/s^2

Hence the acceleration will be 10m/s^2

Answer:

One: either C or D. I can't give you a definite answer. See below.

Two: D

Explanation:

F = m * a

F = 895 N

a = 9.8

m = F/a

m = 895/9.8

m = 91.82

This turned out to be a very nasty little question. I don't know how you should answer it. The closest answer is C but is it close enough? You have to decide if you've had approximation questions before. If you have, C is the answer. If not then D is what you should choose.

1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”

This law also called law of inertia

2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”

3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.

These forces are called action and reaction forces

Answer:

it would be 3

Explanation:

because you have to divide the length by the height of the incline.

The mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.

Mechanical advantage is a measure of the ratio of output force to input force in the system, it is used to obtain the efficiency of a mechanism.

The formula for the mechanical advantage of the inclined plane is found as;

[tex]\rm Mechanical \ advantage = \frac{length}{height} \\\\ Mechanical \ advantage =\frac{9}{3} \\\\ Mechanical \ advantage =3[/tex]

Hence the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.

Answer:

3.5 A

Explanation:

Current [A] =Electrical power [W] ÷ Potential difference [V]

KW TO W = ×1000

hence,

800W÷230V= 3.5A (1 d.p)

The current through a television with a power of 0.8kW if it uses 230V mains supply is 3.5A

Current is as a result of the flow of electrons through a conductor.

Voltage is the difference in potential between two points.

Power is the product of current and voltage. It is given by:

Power(P) = Current(I) * Voltage(V)

Given a power of 0.8 kW = 800W, V = 230 V. Hence:

P = IV

800 = 230I

I = 3.5A

The current through a television with a power of 0.8kW if it uses 230V mains supply is 3.5A

Answer:

F = 3.01 N

Explanation:

Given that,

Mass of a block, m = 2.75 kg

Force applied to the block, F = 5.11 N

It is directed 53.8° above horizontal.

We need to find the total force acting on the block. The force acting on it is given by :

[tex]F=F\cos\theta\\\\F=5.11\times \cos53.8\\F=3.01\ N[/tex]

So, 3.01 N of force is acting on the block.

3.01 works as the right answer
