A) It would be doubled.
Why?
To answer the question, we just need to calculate the momentum of the basketball using the following formula:
Now, we have calculated the momentum and the result is 12 kg.m/s, what would happen to the velocity if we double the momentum? Let's calculate it!
Hence, we can see that if the momentum is doubled, the velocity will be doubled too.
Have a nice day!
Complementary is essentially two things that are "combined" with one another (complement one another) to make a bigger piece or make it better.
Answer:
Vrms = 291 m/s
Explanation:
The root mean square velocity or vrms is the square root of the average square velocity and is. vrms=√3RTM. Where M is equal to the molar mass of the molecule in kg/mol.
Temperature = 365 K
Root mean square velocity = ?
molar mass of oxygen = 16 g/mol.
But xygen gas (O2) is comprised of two oxygen atoms bonded together. Therefore:
molar mass of O2 = 2 x 16
molar mass of O2 = 32 g/mol
Convert this to kg/mol:
molar mass of O2 = 32 g/mol x 1 kg/1000 g
molar mass of O2 = 3.2 x 10-2 kg/mol
Molar mass of Oxygen = 3.2 x 10-2 kg/mol
Vrms = √[3(8.3145 (kg·m2/sec2)/K·mol)(365 K)/3.2 x 10-2 kg/mol]
Vrms = 291 m/s
Answer:
Explanation:
Given that:
Charge Q = 10400 C
current I = 0.530 mA
From our previous knowledge, we know that charge Q can be expressed as:
Q = I×t
where
I = current and t = time
∴
replacing our values
10400 = (0.530×10⁻³) t
t = 10400/(0.530×10⁻³)
t = 19622641.51 seconds
However, the required flow of electrons per seconds can be calculated by using the formula:
number of electrons/second = current (I)/ charge on electron
= (0.530×10⁻³)/(1.6×10⁻¹⁹)
= 3.3125×10¹⁵ electrons
Answer:
The correct option is D
Explanation:
Generally, thermal and electrical conductivity is affected by valence electrons in an atom. These valence electrons carry electric charges (or conduct heat as the case may be) throughout the atom. The fewer the valence electrons, the higher its conductivity - this is as a result of free movement within the atom. The higher the valence electrons, the lesser its conductivity and when the outermost electrons have completely filled the outermost shell, the atom would be an insulator as there won't be carriers of electric charges.
Hence, from the above, sodium would be expected to have the highest electrical and thermal conductivity because it has just one electron in it's outermost shell
