Answer:
Water has more kinetic energy because it is liquid, as ice is harder, so it's cells can't move as much.
A, B, and C are all incorrect because they are talking about springs. I'm assuming you're talking about a 2 dimensional, side to side pendulum. In that case, the answer is D because as the pendulum goes up from one side, gravity accelerates it downward until it swings to the other side. If you're not talking about this type of pendulum, leave a comment and ill come back.
Answer:
3.6 x 10⁻⁷ H
Explanation:
C = capacitance of the capacitor = 6.57 x 10⁻¹² F
L = inductance of the inductor = ?
f = frequency of broadcasting system = 103.9 MHz = 103.9 x 10⁶ Hz
frequency is given as


Inserting the values
L = 3.6 x 10⁻⁷ H
Answer:
maximum possible speed by solving above equation for 7D is

minimum possible value of speed for solving x = 6D is given as

Explanation:
Let the nozzle of the hose be at the origin. Then the nearest part of the rim of the tank is at (, ) = (6, 2) and the furthest part of the rim is at (, ) = (7, 2).
The trajectory of the water can be found as follows:


Now from above two equations we have

now we know that height of the cylinder is 2D so we have

by solving above equation we have

now we know that maximum value of x is 7D
so the maximum possible speed by solving above equation for 7D is

minimum possible value of speed for solving x = 6D is given as
