Answer:
The answer is "[tex]5.184 \times 10^{23}[/tex] kg"
Explanation:
Given:
[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]
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?
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.

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?
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.

What is resultant force ?Resultant force is a summation of all force which act on a point or object. It will be either negative or positive i.e if we takes on direction is positive then other three direction will be taken in negative and then add all force so the outcome is called resultant force acting on a object. Mass is a physical quantity which is measured in kilograms . It will neither depend on any other quantity.
It is also doesn't depend on acceleration due to gravity like weight is depend on acceleration due to gravity but mass is not .Weight is varies from one place to another place but mass doesn't depend on place or position.
Therefore, Energy Production in the Mitochondria because of the lack of less oxygen one want to build up more ways to get more energy production.

Newton theorized that the apple would experience the accelerating effect of the force of gravity no matter how far from the Earth the apple was. He expanded this idea to all objects near the Earth. What was Newton's explanation for why the moon doesn't crash to the Earth due to gravitational force? Do we use this principle for any application today? Give an example, if so.
Answer:
The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed,
Explanation:
Newton explained that all objects attract each other, as the Earth is much greater than the apple, it is this that falls towards the Earth.
The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed, in general this acceleration is called centripetal
[tex]a_{c} = g[/tex]
This principle is used in all circular motion devices, for example the merry-go-round in parks, the radius of the circle is proportional to the speed of the turn and therefore to the centripetal acceleration of the device.
An electric energy distributor supplies each household 220
volts of voltage and 60 A of current. Applying your knowledge on Ohm's Law, in what way your appliances be used at home to maintain a safe amount of current?
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

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!!
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.

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
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.

In the experiment shown below, which is greater, the force of gravity on the pith balls (Fg) or the electrostatic force between them (Fq)?
Fg > Fq
Fg = Fq
Fg < Fq
Not enough information is given.
Answer: Fg < Fq
Explanation: just took the lab test edge 2020
The electromagnetic force is greater than the gravitational force option third Fg < Fq is correct.
What is the electrostatic force?It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge separated by r is determined by the charge potency of each charge as well as the separation distance between them.
Force of gravity is given by:
[tex]\rm F_g=\dfrac{Gm_1m_2}{r^2}[/tex]
The electrostatic force is given by:
[tex]\rm F_q = \dfrac{kq_1q_2}{r^2}[/tex]
On the atomic scale, electrons, for example, have very little mass but a very large charge. As a result, electromagnetic forces rule.
Thus, the electromagnetic force is greater than the gravitational force option third Fg < Fq is correct.
