Does an astronaut have more mass on earth then space? why or why not?
Answers
Answer:
No
Explanation:
No, his mass remains the same no matter where he is in the universe.
But then again the moon has less gravitational pull, therefore your weight and mass will be smaller in space and on the moon than on earth

A car is moving with the a speed of 25m/s.Calculate the distance travelled the car in 30seconds
Answers
Answer:
750 m
Explanation:
Hi there!
We're given that:
⇒ The speed of the car is 25 meters/second
⇒ The car travelled a certain distance in 30 seconds
To calculate distance, use the formula:
Distance = Speed × Time
Distance = 25 × 30
Distance = 750
Therefore, the car travelled a distance of 750 m in 30 seconds.
I hope this helps!
Answer:
[tex]\boxed {\boxed {\sf 750 \ meters}}[/tex]
Explanation:
We are asked to find the distance a car traveled. Distance is the product of speed and time.
[tex]d= s \times t[/tex]
The speed of the car is 25 meters per second. The time is 30 seconds.
s= 25 m/s t= 30 s[tex]d= 25 \ m/s * 30 \ s[/tex]
The units of seconds cancel each other out.
[tex]d= 25 \ m * 30[/tex]
[tex]d= 750 \ m[/tex]
The car traveled 750 meters in 30 seconds at a speed of 25 meters per second.

A tire company wants to determine what kind of rubber will last the longest for their tires. What are some variables that the researchers will want to make controlled variables?
Answers
In an experiment, we can define 3 types of variables.
Independent variables: Are these ones that the scientist can control and modify, in this case, would be the kind of rubber for the tires.
Dependent variables: Are the variables that react to the changes in the independent variables. In this case, would be "how much lasts each type of rubber".
Controlled variables: Are all of these variables that also have an impact on the dependent variable, so we need to control them (fix them) so they do not affect the study of the independent variable.
So, for this particular experiment, to find controlled variables we need to think on what things do affect the durability of tires.
Some examples can be:
The material of the ground where the tires are being tested.The temperature of the ground where the tires are being tested.The type of car where the tires are being tested.The speed at which the tires are being tested.The internal pressure at which the tires are being tested.If you want to learn more, you can read:

1) you would have noticed water vapour forming on the inside of the glass jar, where did this water come from?
hint: Think about what happens in a combustion in a combustion reaction.
2) explain why the water rises in the glass jar?
Answers
Answer:
1) Condensation.
2) See below.
Explanation:
1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.
2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.

if electromagnetic radiation has a frequency of 2.0 x 10^15 s^-1 what is the radiation’s energy?
Answers
[tex]1.3\times 10^{-18}[/tex] Joule is the radiation’s energy.
Explanation:
The energy of electromagnetic radiation is given by Planck's law:[tex]E=h\times \nu[/tex]
Where:
E = Energy of electromagnetic radiation
h = Planck's constant=[tex]6.626\times 10^{-34} Js[/tex]
[tex]\nu[/tex] = frequency of the electromagnetic radiation
Given:
The frequency of the electromagnetic radiation =[tex]\nu = 2.0\times 10^{15} s^{-1}[/tex]
To find:
The energy of the electromagnetic radiation
Solution:
The frequency of the electromagnetic radiation = [tex]\nu = 2.0\times 10^{15} s^{-1}[/tex]
The energy of the radiation = E
[tex]E=h\times \nu\\E=6.626\times 10^{-34} Js\times 2.0\times 10^{15} s^{-1}\\=1.3\times 10^{-18} J[/tex]
[tex]1.3\times 10^{-18}[/tex] Joule is the radiation’s energy.

Answers
Answer: 37 protons, 48 neutrons, and 36 electrons.
Explanation: I assume "Revision" is Rubidium. It is atomic number 37, so it has 37 protons. It's atomic mass is 85, so it has an average of (85-37) = 48 neutrons. It has a charge of +1, so one electron of the original 37 has left.
