Answer:
c) Anti-top
Explanation:
Protons are particles which belong to the hadron group of particles. The antimatter equivalent particle is antiproton
Electrons are particles that belong to the fermion group of particles. The antimatter equivalent is antielectron
Antitop quarks are particles that belong to the group family of particles. They are the antimatter equivalent of top quarks.
Gluons are particles that belong to the group of particles called bosons.
Tau neutrinos are particles that belong to the fermion group of particles. The antimatter equivalent is Tau antineutrino.
Answer:

Explanation:
As we know that the current through the battery is given as

here from above equation we know that current will become zero when time elapsed is very large
so here we can say that charge will flow through the battery from t = 0 to t = infinite
now we have





As we know that




Answer:
The height is 0.1014 m
Explanation:
Given that,
Mass = 0.0400 g
Charge 
Time t = 0.0420 s
Electric field 
We need to calculate the electric force on the particle
Using formula of electric force

Put the value into the formula


We need to calculate the gravitational force
Using formula of force

Put the value into the formula


We need to calculate the net force



We need to calculate the acceleration
Using newton's law




We need to calculate the height
Using equation of motion



Hence, The height is 0.1014 m
The temperature of the water getting colder would cause the liquid in the thermometer to drop due to less heat being transferred from the water to the liquid, so the liquid molecules are closer than when they have high energy.
