The kinetic energy is transferred to thermal energy through friction
Answer:
1.86 × 10 ∧-3 V/m
≅ 1.9 × 10 ∧-3 V/m
Explanation:
Radius of long solenoid (R)= 3 cm
Turns per meter (n) = 2500
current flowing in coil (I) = 0.30 sin (200 t)
Time (t) = 2.5 ms
Distance at which electric field calculated (r) = 4 cm
The main solution is shown in the picture attached below.
Thank you and i hope it helps.
(mu s) is the coefficient of kinetic friction, <span> (mu k) is a normal force,</span>
It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
<u>Explanation:</u>
v = u + at
68.6 ms^-1 = 0 ms^-1 + (9.8 ms^-2 x t)
t = 68.6 ms^-1 / 9.8 ms^-2
t = 7.0s
It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
Answer:
10.23m/s^2
Explanation:
GIven data
mass of elevator = 2125 kg
Force= 21,750 N
Required
The maximum acceleration upward
F= ma
a= F/m
a=21,750/2125
a= 10.23m/s^2
Hence the acceleration is 10.23m/s^2
