Answer:
Our weight on the moon is less than it would be on Earth due to a difference of the strength of gravity on the moon. The moon's gravitation force is determined by the mass and the size of the moon. ... This means that if you went to the moon you would weigh less, even though your mass stays the same!
Explanation:
The mass and weight of a person would be less on the moon on the earth because the gravitational force on the moon is less than that on the earth.
What is gravitational force?Gravitational force is the one by which all things pull onto the ground. It pulls everything towards itself. Gravity is present everywhere, but not in the same amount.
Gravity defines the weight of an object. On Earth, the weight is an object would be higher, than the planet, like Mars and the moon. The earth revolves on its axis and around the sun due to gravitational force.
The moon has a smaller mass than the earth and its pulling gravitational strength is also less, which is 1/6th of the earth.
Thus, Due to the moon's lower gravitational pull than the earth's, a person would have a lower mass and weight on the moon.

6.72 x 10^12 in standard form
Answer:
6.72*10¹²= 6,720,000,000,000 in standard form.
Explanation:
Scientific notation is a quick way to represent a number using powers of base ten.
The numbers are written as a product:
a * 10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10. n is an integer called an exponent. Represents the number of times the comma is shifted. If the exponent is positive, move the decimal point to the right. And if the exponent is negative, move the decimal point to the left.In this case 12 is a positive number, so the decimal point is shifted to the right 12 places.
So, 6.72*10¹²= 6,720,000,000,000 in standard form.

Temperature is read by measuring the liquid in the thermometer using the scale on the thermometer. When the temperature rises, the liquid in the thermometer
. When the temperature drops, the liquid in the thermometer
Answer:
Temperature is read by measuring the liquid in the thermometer using the scale on the thermometer. When the temperature rises, the liquid in the thermometer rises. When the temperature drops, the liquid in the thermometer drops.
Explanation:
got it right on edge
When the temperature is increase so the liquid in the temperature should be rised.
When there is a fall in the temperature the liquid in the thermometer should be fallen.
Working of thermometers:
The temperature should be read via calculating the liquid in the theromemeter by applying the scale occur in the thermometer. At the time when the temperature is increase so the liquid in the temperature should be rised. While on the other hand, When there is a fall in the temperature the liquid in the thermometer should be fallen. This means it shows the direct relationship between them

A 5.0 km race is scheduled for this weekend. How many miles is this race?
Answer:
3.10686
Explanation:
A 5.0 km race is scheduled for this weekend. Total miles is this race is 3.10686.
What is kinetic energy?Kinetic energy is a form of energy it possess when any object or person is in motion . It can be defined as the work needed to be done to produce a motion in a object from rest position.
If we want to acceleration in an object then we must apply a force on a object to give motion so we can say that we required to do work for acceleration and then we can say that required is equal to kinetic energy.
Mathematically,
Kinetic energy =1/2mv^2
Where
m = mass of object.
v = velocity of object
Kinetic energy is vector quantity it means that it have both i.e magnitude and vector. . It can be defined as the work needed to be done to produce a motion in a object from rest position.
S.I unit of Kinetic energy is Joule.
Therefore, A 5.0 km race is scheduled for this weekend. Total miles is this race is 3.10686.

apply.
O A solution of rubbing alcohol and water.
A solution of salt and water.
An alloy of copper and gold.
O A solution of sugar and water.
The solutions which can be separated using distillation are that of alcohol, salt and sugar with water.
What is distillation ?It is defined as a process by which components are separated from a mixture which is liquid by selective boiling and condensation. Dry distillation is a process of heating solids to produce products in gaseous state.
Distillation results in complete separation of components or may be sometimes partial.Due to partial separation,concentration of selected components increases in the mixture. It exploits differences in relative volatility of components of a mixture.
It has many applications like distillation of fermented products which produces distilled beverages , in desalination and in petroleum and oil industry.
It is mainly conversion of liquid into vapor state ,which is subsequently converted back to liquid . It is used to separate volatile liquid from solids and also volatile liquids and non-volatile liquid .

Chlorine–35 has 17 protons. How many protons and neutrons does the isotope chlorine–36 have? 19 protons and 17 neutrons 17 protons and 18 neutrons 17 protons and 19 neutrons 18 protons and 17 neutrons
Answer:
17 protons
19 neutrons
Explanation:
Chlorine will always have the same amount of protons, and that would be 17 protons.
The atomic mass will change according to how many neutrons are present.
Cl - 35 is comprised of 17 protons and 18 neutrons.
We want to find Cl - 36:
We simply add 1 neutron. 18 + 1 = 19 neutrons.
Two bottles are connected with a valve. In bottle A, there are 2.4 L of nitrogen gas at 1.8 atm. In bottle B, there are 4.8 L of nitrogen gas at 1.8 atm.
After opening the valve, what is the pressure of nitrogen gas?
Please answer in atmospheres.
I will give brainliest please answer quickly!
My
Answer:
1.8 atm
Explanation:
For bottle "A"
P1 = 1.8 atm V1 = 2.4L, P2 = ?, V2 = 2.4 + 4.8 L = 7.2 L,
Thus using P1•V1 = P2•V2, we have;
P2 = (1.8 × 2.4)/7.2 = 0.6 atm
For bottle "B"
P1 = 1.8 atm, V1 = 4.8L, P2 = ?, V2 = 7.2L,
P2 = (1.8 × 4.8)/7.2 = 1.2 atm
We will now add the individual pressures of each bottle;
Total pressure = P(A) + P(B)
Total pressure = 0.6 + 1.2
Total pressure = 1.8 atm.

In one second an ant dragged an object 1 mm. What was its speed in cm/min?
Answer:
The speed of the ant is 6 [tex]\frac{cm}{min}[/tex]
Explanation:
Speed is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, velocity relates change in position (or displacement) with time by:
[tex]speed=\frac{distance}{time}[/tex]
In this case:
speed= ?distance= 1 mmtime= 1 secondReplacing:
[tex]speed=\frac{1 mm}{1 second}[/tex]
Being 1 mm equivalent to 0.1 cm and 1 seconds equal to 0.01667 minutes then:
[tex]speed=\frac{1 mm}{1 second}=\frac{0.1 cm}{0.01667 min}[/tex]
speed = 6 [tex]\frac{cm}{min}[/tex]
The speed of the ant is 6 [tex]\frac{cm}{min}[/tex]
