Answer:

[tex]F=1.98\times 10^{20}\ N[/tex]

Explanation:

Given that,

The mass of a Moon, [tex]M_m=7.35\times 10^{22}\ kg[/tex]

The mass of the Earth, [tex]M_e=5.98\times 10^{24}\ kg[/tex]

The moon's mean orbit distance around the earth is, [tex]r=3.84\times 10^8\ m[/tex]

We need to find the gravitational force exerted on the moon by the Earth.

The formula of gravitational force is given by :

[tex]F=G\dfrac{M_mM_e}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{7.35\times 10^{22}\times 5.98\times 10^{24}}{(3.84\times 10^8)^2}\\\\F=1.98\times 10^{20}\ N[/tex]

So, the required force is [tex]1.98\times 10^{20}\ N[/tex].

Answer:True

Explanation:there are approximately 29.531 on the new moon and and 7.31 I think for the first quarter then it’s 7 days between them if u calculate their sped that light travels and that number it might be the same but the statement is true not false

Answer:

The full cycle of moon phases averages 29.531 days. A quarter of that is 7.38 days. So "7 days" is a pretty good approximation for casual conversation. It's true.

Explanation:

uh i think that was my explanation soooooo like yall have a good day and if you are working at 1am just know it is not gonna be so hard one day it is gonna get better hehe

Answer:

P = 15 [W]

Explanation:

Power is defined as the relationship between work over a certain time.

In this way we must calculate the work which is defined as the product of force by distance.

[tex]W=F*d\\W=75*20\\W=1500[J][/tex]

And the power.

[tex]P=W/t\\P=1500/100\\P=15[W][/tex]

Power given in units of watts.

Answer:

4N

Explanation:

Given parameters:

Weight of stone when immersed in water  = 18N

Weight of water displaced  = 4N

Unknown:

Weight of the stone in air  = ?

Solution:

To solve this problem, we employ the Archimedes' principles.

It states that the upward buoyant force on a body is equal to the weight of the fluid displaced.

The weight of the water displaced is equal to the weight of the body.

So, the weight of the stone in air  = 4N

Explanation:

Force (F) = 500 N

Distance (d) = 16 m

work done (w) =?

We know that

w = F * d

= 500 * 16

= 8000 Joule.

The bulldozer performs 8000 Joule.

Answer:28m/s

Explanation:I got one point so yeah hope this help

When a car traveling at 10 m/s accelerates at 3 meters/ second² for 6 seconds, then the final velocity of the car would be 28 meters per second.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

As given in the problem, a car traveling at 10 m/s accelerates at 3 m/s^2 for 6 seconds,

the initial velocity of the traveling car = 10 m/s

time =  6 seconds,

acceleration = 3 meters/ second²

With the help of the first equation of the motion, we can calculate the final velocity of the car,

v = u + at

v = 10 + 3*6

v = 28 m/s

Thus, the final velocity of the car would be 28 meters per second.

Answer:

2. F g decreases to 1/9

Explanation:

The formula for calculating the Force of gravity between two masses separated by a distance is expressed as;

F = GMm/d² ... 1

If the distance is tripled, the new force will be;

F1 = GMm/(3d)²

F1 = GMm/9d² ... 2

Divide equation 1 by 2

F/F1 = GMm/d²÷GMm/9d²

F/F1 = GMm/d²×9d²/GMm

F/F1 = 1 * 9

F = 9F1

F1 = 1/9 F

This means that the new force decreases to 1/9

Answer:

Coriolis Effect

Explanation:

The Coriolis effect is responsible for the deflection of winds to the right in the Northern hemisphere and to the right in the Southern hemisphere. It is an effect that occurs because of the rotation of the earth around its axis.

The implication of this is that in areas of low pressure in the Northern hemisphere, winds tend to blow in anticlockwise direction, and in areas of high pressure, it blows in a clockwise direction. The opposite of this happens in the Southern hemisphere.

Answer:

physical

Explanation:

Explanation:

The speed of rotation of Venus is slower than that of Earth that is why a day on Venus is longerthan Earth's day. Whereas, Venus is closer to sun than Earth, this means Venus trajectory of revolution is smaller than that of Earth.Therefore, a year on Venus is shorter than Earth's year.

Answer:

The highest conductance results from;

Large cross-sectional area, short pipe

Explanation:

The conductance, G, of a material is a measure of the rate or ease of electricity conduction of the material

[tex]The \ conductance \ G = Current/(Potential \ difference) = \dfrac{I}{V} =\dfrac{1}{R} = \dfrac{A}{\rho \cdot l}[/tex]

Where;

I = The current

V = The voltage (Potential difference)

R = The resistance

A = The cross-sectional area of the conductor

L = The length of the conductor

ρ = The resistivity of the conductor

Therefore, "G" is directly proportional to "A"  ang "G" is inversely proportional to "l" from which we have that as the cross-sectional area increases the conductance increases and as the length of the pipe decreases the conductance increases.

The highest conductance is given by a large cross-sectional area and a short pipe.

Answer:

Large cross-sectional area, short pipe

Formular of kinteic energy is 0.5 × (mass x velocity)²

0.5 × 2500 kg × 35² =1,531,250 jules

Answer:

1.07m/s²

Explanation:

From the question we are given the following

applied force Fapp = 450N

mass of the safe m = 100kg

Weight of the safe W = 980N

coefficient of kinetic friction n = 0.35

Required

Acceleration of the safe

According to Newton's second law

\sum Fx = ma

Fapp - Ff = ma

Ff is the frictional force

Fapp - nmg = ma

450 - 0.35(100)(9.8) = 100a

450 - 343= 100a

107 = 100a

a = 107/100

a = 1.07m/s²

Hence the acceleration of the safe is 1.07m/s²

Answer:

0.25

Explanation:

According to newtons law of motion

\sum F_x = ma

F_f =  ma

nR = ma

nmg = ma

ng = a

n = a/g

g is the acceleration due to gravity

Given

a = 2.42m/s²

g = 9.8m/s²

Substitute into the formula;

n = 2.42/9.8

n = 0.25

Hence the coefficient of kinetic friction is 0.25

Answer:

the same type because they both formed from rock material.

Explanation:

The rocks which are formed from small pieces of rocks are called sedimentary rocks whereas, the rocks formed from the liquid rocks or molten fluid rock, they are called igneous rocks. Hence, A rock A and B are of different types.

There are broadly three types of rocks namely  sedimentary rocks , igneous rocks and metamorphic rocks. These rocks can be interchanged to another forms through the process called rock cycle.

Sedimentary rocks are formed near the earth surface and which are deep within the earth. Sedimentary rocks are composed many  small pieces of rocks. Thus the rock A is sedimentary rock.

Igneous rocks are formed by the crystallization of molten magma after cooling. These magma are developed underground in the upper mantle. Magma becomes hot by the convection current and it flow making the nearby plates to move. When it cools, it solidifies to form igneous rocks. Thus, rock B is igneous type.
