Answer:
The time for both of the balls to reach the ground would be the same.
Explanation:
If no air resistance is present, the rate of descent depends only on how far the object has fallen, no matter how heavy the object is. This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. ... In air, a feather and a ball do not fall at the same rate.
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 best answer to the question that is being stated above would be the first choice. To disprove the claims of the student that you need more protons to have more reactivity, then you proceed to compare the reactivities of lithium (Li) and krypton (Kr). Krypton has more protons than Lithium, but it is less reactive because it is a noble gas.
From Largest to Smallest:
Earth > Biosphere > Biome > Ecosystem > Community > Population > Organism > Organelles
Hope this helps!
