Answer:
Acceleration /Speed
Explanation:
An objects Velocity can be determined by acceleration,
Please pay attention in your middle school class, speed and velocity quiz.
Answer:
35meV
Explanation:
To find the average translational kinetic energy you use the followinf formula:
K_B: Boltzman' constant = 1.38*10^-23 J/K
T: standard temperature = 273.15K
By replacing these values you obtain:
in eV you have:
5.65*10^-12(6.242*10^18eV)=0.035eV=35meV
Hence, the average translational energy is 35meV
The addition of antifreeze to
water in a car radiator causes the freezing point of the mixture to increase. The
answer is letter A. It protects the car radiator from freezing due to cold
temperatures. It is added below the freezing point of water to prevent it from
solidifying.
