Answer:
D
Explanation:
Let’s calculate the kinetic energy for all of the choices.
a. (1/2)(100)(100)^2 = 50(10000)=500,000
b. (1/2)(100)(1)^2 = 50
c. (1/2)(10)(100)^2 = 5(10000) = 50,000
d. (1/2)(1)(1)^2 = 0.5
We can see that (d) has the least kinetic energy.
Answer:
= 729 Joules
Explanation:
Heat absorbed by a substance is given by the formula;
Q = m×c×ΔT
Where; Q is the heat absorbed
m is the mass of the substance
ΔT is the change in temperature;
The specific heat capacity of iron is 450 J/Kg/K
Therefore;
Heat absorbed = 0.06 kg × 27 × 450
= 729 Joules
Both
Explanation: the thing is you will adapt to your environment in order to survive I know this because if you live in a environment where a whole bunch of people get sick, you will get a stronger immune system when you are born.Your genes also come from you family members to. That is why the answer is both. Have a nice day!
