Answer:
option B
Explanation:
Current unit is ampere (A)
Ampere will be equivalent to = ?
we know,
Current can be define as the charge per unit time
unit of charge(Q) is coulomb which is equal to C.
unit of time(t) is equal to 's'.
now,
unit of I = C/s
ampere(A) is equivalent to C/s
The correct answer is option B
Answer:
Explanation:
Let´s find the capacitor impedance:
Using the data provided:
Ω
Now let´s find the capacitance:
μF
We can calculate the capacitor impedance for the second case:
Ω
Finally we can calculate the voltage of the second generator:
Answer:
A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same
B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same
Explanation:
A vehicle crash problem must be solved with the equation of the moment,
Initial instant Before crash
p₀ = m v₁ + mv₂
After the crash
= m
+ m
p₀ =
If the speed ratio before and after the crash is one
p₀ / = 1
We can assume that initially one of the cars was stopped
m v₁₀ = m
v₁₀ =
For the two speeds to be equal, the masses of the vehicles must be the same.
A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same
B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same
