A student uses a meter to measure 120 coulombs flowing through a circuit in 60 seconds. The electric current in this circuit will be 2 A
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A.
current = charge / time
given
time = 60 seconds
charge = 120 Coulombs
current = Q / T = 120 / 60 = 2 A

Answer:
They hit the ground at the same time
Explanation:
Mass doesn't matter in free fall. As long as they were released with the same velocity and the same height, they'll hit the ground at the same time
Answer:
False.
Explanation:
Removing the radiator cap will harm you. If the engine is hot and you open the radiator cap then it will cause the liquid boil, pushing the coolant out of the radiator and spraying around the liquid which can harm the person who is opening that cap. So you should aware of the risk and be prepared to avoid danger.
Answer:
Option C=> π+.
Explanation:
Just as it is given in the question above, we can see that the addition or combination of proton and neutron gives what is known as QUARKS.
Quarks are not easily measured because one can not see and study a quark independently; quarks move in multiples together.
The study of Quarks is very important in physics because they relate very well with electromagnetic force, strong force, weak force and Gravitational force.
"...When the remaining quarks combine to form a single particle, it is a π+".
π+ is a meson or a pion and it contains quarks and anti-quarks too
