BLANK 1: A) Not balanced
BLANK 2: B) Sodium
BLANK 3: B) Not Equal
Answer:
the energy when it reaches the ground is equal to the energy when the spring is compressed.
Explanation:
For this comparison let's use the conservation of energy theorem.
Starting point. Compressed spring
Em₀ = K_e = ½ k x²
Final point. When the box hits the ground
Em_f = K = ½ m v²
since friction is zero, energy is conserved
Em₀ = Em_f
1 / 2k x² = ½ m v²
v = x
Therefore, the energy when it reaches the ground is equal to the energy when the spring is compressed.
Answer:
efficiency = useful energy out ÷ total energy in (for a decimal efficiency)
or.
efficiency = (useful energy out ÷ total energy in) × 100 (for a percentage efficiency)
Explanation:
Answer:
0.054 A
Explanation:
We have given inductance
Capacitance
Charge
The energy stored in the LC circuit is given by
So energy
This energy is also equal to
So
i=0.054 A
So maximum current will be 0.054 A
