Answer:
From ohms law,
V=IR
R=V/I =12.0/150 =0.08 ohm.
Answer:
Explanation:
Given:
Initial Velocity, u = 0 km/s (at rest)
Final Velocity, v = 16 km/s
Time taken, t = 3 sec
acceleration, a = (v - u)/t
= (16 - 0)/3
= 5.33 km/s^2
While Jane is running has a kinetic energy, which is Ek = 1/2*m*v^2 where m is mass and v is velocity When she grabs a vine, she is going to change the kinetic energy to potential energy.
We know that potential energy is given by Ep = m*g*h where m is mass, g is gravity constant and h is height
So while running the kinetic energy is Ek = 1/2 * m * 5.2^2 = 13.52*m
Then all that energy is used to swing upward and gain potential energy
Ep = m*g*h = Ek = 13.52*m
m*9.8*h = 13.52*m
h = 13.52/9.8 = 1.38 meters
So Jane will swing 1.38 meters upward
Index of refraction of a substance =
(speed of light in vacuum) / (speed of light in the substance)
Index in quartz = (2.9979 x 10⁸ m/s) / (2.0567 x 10⁸ m/s)
<em>Index = 1.4576 </em> (no units)
The trampoline is loaded with multiple springs that counteract the gravitational forces of the mass of the child. If the Forces of the springs are bigger than the gravitational force of the child, the child will rise in the air.
