Answer:
Explanation:
A ball is thrown vertically upward with a certain Kinetic Energy in the absence of air resistance and while returning it experiences air resistance.
Air resistance causes the ball to lose its kinetic energy as it provides resistance which will convert some of its kinetic energy to heat energy.
So in a way total energy is conserved but not kinetic energy as some portion of it is lost in the form of heat.
The answer is 6.
Add 4 then divide 2. You should have 18 after you do that, subtract 10 then multiply 20. You then have 6.
A wave transfers energy from the source outward in the
direction of wave motion.
To add, <span>in physics, a </span>wave<span> is an oscillation accompanied by a transfer of
energy that travels through a medium (space or mass). Frequency refers
to the addition of time.</span>
Explanation:
Acceleration is the change in speed over a given time period
If silicic rock is found in a core sample, its location is likely underneath an ocean or a mountain.
Answer: Option A
<u>Explanation:</u>
Silicic rock are the type of rocks which are made up of silica and are located at the crust of the earth which is more likely to the core lying underneath and it extends all the way up to 30 km.
Its density is around 2 gm / cm^3 .One of the common example of silica is granite. So if the silicic rocks are found in a core it is more likely underneath the ocean or mountain.
