Answer:
11.025m
Explanation:
Using kinematics,
u = Initial velocity = 0.
t = Time taken = 1.5sec.
a = Acceleration from gravity = 9.8m/s^2
Distance = s
= ut + 1/2 * a * t^2
= 0 + 1/2 * 9.8 * (1.5)^2
= 11.025m
Answer:
64.5
Explanation:
(m1 + m2) v initial = (m1 * v1 final) + (m2 * v2 final)
(92 + 8)(-7) = (92 x 2) + (8 x v2 final)
(100)(-7) = (184) + (8 x v2 final)
-700 = (184) + (8 x v2 final)
-516 = (8 x v2 final)
-516/8 = v2 final
-64.5 = v2 final
Answer: Rr = 900w
T = 1.66×10^-5s
P = 36.92W
Explanation: please find the attached file for the solution.
Answer:
4A
Explanation:
Current is charge per time. So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.
2 × 2A = 4A
