The ampere (symbol: A) is the SI base unit of electric current equal to one coulomb per second.
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 times 10–7 newton per meter of length.
Electric current is the time rate of change or displacement of electric charge.
One ampere represents the rate of 1 coulomb of charge per second.
The ampere is defined first (it is a base unit, along with the meter, the second, and the kilogram), without reference to the quantity of charge.
The unit of charge, the coulomb, is defined to be the amount of charge displaced by a one ampere current in the time of one second.
This is your answer friend. Hope it helps you.
Answer:
a=g.
the body is in one of these INGRAVIDITY, so the weight of the body would be ZERO
Explanation:
When the spacecraft revolves around the Earth, it is subjected to Newton's second law
F = m a
where the force is the universal attractive force, the mass of the astronauts, and the centripetal acceleration.
a = F / m
a = (G M m / r²) / m
a = G M / r²
the amount of is the acceleration of gravity at height r.
a = g
Therefore, we see that the acceleration of the body is equal to the acceleration of gravity, which is why the body is in one of these INGRAVIDITY, so the weight of the body would be ZERO
Answer:
4 Km/hr
Explanation:
Data obtained from the question include the following:
Mass of ball (Mb) = 15 Kg
Velocity of ball (Vb) = 20 Km/hr
Mass skater (Ms) = 60 Kg
Velocity of skater (Vs) = 0 Km/hr
Velocity after collision (V) =..?
Thus, we can obtain the velocity after collision as follow:
MbVb + MsVs = V(Mb + Ms)
(15 x 20) + (60 x 0) = V (15 + 60)
300 + 0 = 75V
300 = 75V
Divide both side by 75
V = 300/75
V = 4 Km/hr.
Therefore, the velocity after the collision is 4 Km/hr.
