Because acceleration is not speed, and speed is not acceleration.
I'm sure you would not ask "Why isn't temperature given in acres,
as it is for area ?" Speed and acceleration are different things, so
it's only natural that they have different units.
The magnitude (size) part of acceleration is:
(how much speed changes) per second.
Are you speeding up ?
Are you traveling (2 meters per second) faster every second ?
Then your acceleration is
(2 meters per second) per second .
When you write that phrase as an algebraic expression, it's
(2 m/sec) / sec
and when you simplify that fraction, you get 2 m/sec² .
Answer:
The material effects the speed if sound.
Explanation:
A denser material whose atoms are tightly packed will quickly transfer energy as they are close to each other than mediums like air.
The energy required to heat a substance is related by the formula:
Q = mCpΔT ; where Q is the energy, m is the mass of the substance, Cp is the specific heat capacity and ΔT is the change in temperature.
2000 = (4)(Cp)(5)
Cp = 100 Joules / g °C
Because of the location of Mg on the periodic table.
heat capacity: The capability of a substance to absorb heat energy; the amount of heat required to raise the temperature of one mole or gram of a substance by one degree Celsius without any change of phase.
is this what ur asking?
