[tex]g= 6.003 \ \frac{m}{s^2}\\\\G= 6.67 \times 10^{-11} \ \frac{N - m^2}{kg^2}\\\\M=?\\\\radius= 2,400 \ km\\\\[/tex]

Calculating diameter:

[tex]Diameter =radius \times 2[/tex]

                [tex]=24\times 10^5 \times 2\\\\=48 \times 10^5 \ m[/tex]

The formula for mass calculation:

[tex]\to g = G \times \frac{M}{(\frac{d^2}{4})}\\\\\to g=G\times \frac{4M}{d^2}\\\\\to 4M= \frac{g \times d^2}{G} \\\\\to M= \frac{g \times d^2}{4G} \\\\[/tex]

         [tex]=\frac{6.003 \times (48 \times 10^{5})^2}{4 \times 6.67 \times 10^{-11}}\\\\=\frac{6.003 \times 2,304 \times 10^{10}}{26.68\times 10^{-11}}\\\\=\frac{13,830.912 \times 10^{10}}{26.68\times 10^{-11}}\\\\=518.4 \times 10^{21}\\\\= 5.184 \times 10^{23}\\\\[/tex]

Why is air warmer near Earth's surface?
A.
The Sun heats Earth's surface, and in turn the air above it is heated.

B.
Warm air is more dense and sits on top of Earth's surface.

C.
Warm air is less dense and sits on Earth's surface HELP PLZ!!

Answers

Answer:

I am pretty sure it is A!

:D

The air is warmer near Earth's surface because warm air is denser and sits on top of the Earth's surface. The correct option is B.

What is air density?

The mass of the air per unit volume is known as the air density. Its unit is kg/m³.

Due to the lower pressures in the air above, air expands when it rises. cooling air expands.

The hottest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends.

Because warm air is denser and lies on top of the surface of the Earth, it is warmer near the surface of the earth.

Hence, the correct option is B.

A lava lamp is a decorative item found in some homes. The lamp portion contains a waxy substance in a liquid medium. When the lamp is plugged in, a bulb at the base of the lamp slowly heats the waxy substance sitting at the bottom of the liquid. Eventually, the waxy substance will separate into globs that quickly rise to the top of the lamp where the surrounding liquid cools them and causes them to fall back to the bottom. Based on the information provided, a lava lamp could be used to provide an example of which process of thermal energy transfer?

Answers

Answer:

Conduction, convection, and radiation

Explanation:

Conduction is the process in which energy is transferred from a hot body to a cooler body. Convection is a process by which heat is transferred as a result of the movement of heated fluid in the form of air or water. Radiation refers to the transmission of energy through a material medium.

Based on the information provided, a lava lamp could be used to provide an example of conduction, convection, and radiation.

Answers

Answer:

the correct one is B,   θ  =  [tex]\frac{1}{4\pi }[/tex]  w t    [rev]

Explanation:

This is a rotational kinematics exercise

        w = w₀ + α t

        w² = w₀² + 2 α θ

indicate that part of rest whereby the initial angular velocity is zero

        w = α t       -> α = w/t

        w² = 2 α θ

we substitute

        w² = 2 (w / t) θ

         w = 2 θ / t

        θ = w t / 2

         

This angle is given in radians, let's reduce to revolutions = 2π rad = 1 rev

        θ = w t / 2 rad (1 rev / 2π rad)

        θ  =  [tex]\frac{1}{4\pi }[/tex]  w t    [rev]

when checking the answers, the correct one is B, even though he has some mistakes in his writing

Which of the following are possible non-SI units to describe the rate of
acceleration? (Choose all that apply)

1) meters per second per minute

2) miles per kilometer per
second

3) miles per hour per second

4) kilometers per hour squared

5) meters per hour per kilometer

6) kilometers per minute

Answers

The possible non-SI units to describe the rate of acceleration is the kilometers per hour squared. That is option 4.

What is acceleration?

Acceleration is the relationship that exists between velocity and time. It is defined as the change of velocity in both speed and direction with respect to time.

The formula for acceleration is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.

Velocity is defined as the rate of objects position with time.

The SI units of velocity = meter/seconds

Substitute for velocity in first equation:

a = meter/sec/sec

a = meter/sec²

But 1000meters = 1 Km

3600 secs = 1 hour

Therefore, the possible non-SI units to describe the rate of acceleration is the kilometers per hour squared.

Average speed for the entire trip

A) 15 km/h

B)30 km/h

C) 60 km/h

D) cannot tell from this data

Answers

Answer:

Option B. 30 Km/h

Explanation:

To solve this question, we must know the meaning of average speed.

Average speed is simply defined as the total distance travelled divided by the total time taken to cover the distance. Mathematically, it is expressed as:

Average speed = Tota distance /Total time

Thus, with the above formula, we can obtain the average speed of the entire trip as shown below:

Total distance = 60 Km

Total time = 2 h

Average speed = Total distance /Total time

Average speed = 60 /2

Average speed = 30 Km/h

Thus, the average speed of the entire trip is 30 Km/h

Answers

Answer:

Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

Explanation:

According to Ohm's law, V = IR

V is the potential difference = 220volts

I is the current = 60 A

R is the resistance (Load)

Calculating the load R

R = V/I

R = 220/60

R = 3.67 ohms

Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

A dog pulls on a leash with a force of 15 23 is a big dog. The leash makes an angle of 36.7 degrees to the horizontal. What are the x

and y components of the force?

Answers

Answer:

[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]

Explanation:

The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N

[tex]Force = 15N[/tex]

[tex]\theta = 36.7[/tex] to the horizontal

Required

Solve for the x and y components

Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.

[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component

[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component

Calculating the y component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Sin\theta = \frac{y}{Force}[/tex] becomes

[tex]Sin(36.7) = \frac{y}{15}[/tex]

Make y the subject

[tex]y = 15 * Sin(36.7)[/tex]

[tex]y = 15 * 0.5976[/tex]

[tex]y = 8.964N[/tex]

Calculating the x component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Cos\theta = \frac{x}{Force}[/tex] becomes

[tex]Cos(36.7) = \frac{x}{15}[/tex]

Make y the subject

[tex]x = 15 * Cos(36.7)[/tex]

[tex]x = 15 * 0.8018[/tex]

[tex]x = 12.027N[/tex]

Hence, the x and y components of the force are: 8.964N and 12.027N respectively.
