Answer:
10cm^3
Explanation:
Given data
Mass of steel = 80grams
density of steel= 8 g/cm^3
We know that the formula for density is given as
density= mass/volume
make volume subject of formula
volume= mass/density
volume=80/8
volume= 10cm^3
Hence, the volume 10cm^3
Answer:
Heat is the energy that flows between two substances of different temperatures.
Explanation:
Heat is a type of energy in transition that is transferred by non-mechanical means between systems, which means that it is energy that is transferred (or that <u>flows </u>) from one system to another.
This flow of energy occurs due to a temperature difference, and heat will flow from the system or substance with a higher temperature to the substance with a lower temperature, and if kept in contact they will eventually reach the thermal equilibrium.
So the correct answer is: Heat is the energy that flows between two substances of different temperatures.
Answer: I believe the right answer would be C
I hope this helps. Correct me if im wrong
<span>You could easily define it this way. This would be valid. But for most of history it was unclear when a baby was conceived, so it would be silly for someone to say their baby was 9 months old when it was actually born at only 8.5 months. Days of conception similarly would not be a good substitute for birthdays because no one would know them. Then in general it was much easier to mark someone's age as when they came into the world as an independent being, and this tradition is far too entrenched (and simple and easy to handle and universal for people in poor countries etc) to think we would at all gain from now finding exactly the date of conception and counting age from that point.</span>
Answer:

Explanation:
As we know that the total mass of the all four players is given as


diameter of the piston of cheer leader is given as

are of cross-section is given as


mass of the cheer leader is given as
m = 55 kg
so the pressure due to cheer leader is given as



Now on the other side pressure must be same
so we have





so diameter on the other side is given as
