Find the force on an object which has a mass of 20 kg and an acceleration of 10 m/s2.

Answers

Answer:

200N

Explanation:

mass = 20 kg

acceleration = 10 m/s^2

Force = mass * acceleration

The first, fourth, and fifth answers are correct.

Substance A has twice the specific heat capacity as substance B. If 1000 J of heat are added to 1.0 kg of each substance, compare the change in temperature of each substance.

Answers

Substance A would have a delta T (change in temp) rise 1/2 the rise in substance B.

Q=mc x delta T

Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.

Solve for change in temp=. Q/mc

Specific heat and mass are not inversely proportional to heat energy input.

Putting into real world scenario of using water to heat a building.

Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF

Acetone specific heat is .51

So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.

The musical tone a piano has a frequency of 346HZ and a wavelength of 1.3 M what is the speed of the sound

Answers

Answer:

v= 449.8 m/s

Explanation:

Given data

Frequency=  346Hz

Wave length= 1.4m

The expression below is used to find the speed

[tex]v= f \lambda\\\\[/tex]

substitute

[tex]v= 346*1.3\\\\v= 449.8 m/s[/tex]

Hence the speed is v= 449.8 m/s

The specific heat capacity of copper is 390 J/Kg AC. What does this
mean?

Answers

Answer:

It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper

Explanation:

390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C

From the given information,

The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.

The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.

Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.
