Answer:
As a substance gains heat energy (in the case of the lava lamp, heat is transferred from the hot light bulb to the lava), it becomes less dense than the surrounding liquid ), causing the substance to rise.
Answer:
P₀ = 5.76 x 10⁻² MW
Explanation:
given,
efficiency of the power plant = 32%
Power produced by the nuclear fission = 0.18 MW
the power plant output = ?
using formula of efficiency

where P is the power produced in the power plant
P₀ is the power output of the power plant


P₀ = 0.18 x 0.32
P₀ = 0.0576 MW
P₀ = 5.76 x 10⁻² MW
Power plant output is equal to P₀ = 5.76 x 10⁻² MW
Answer:
12V
Explanation:
Given parameters:
Resistance = 12ohms
Heat released = 144J
Time taken = 12s
Unknown:
Voltage at the ends of the conductors = ?
Solution:
To solve this problem, we must first determine the power expended by the circuit.
Power is the rate at which work is done;
P = 
= 
= 12W
Electrical power is given as;
P = IV = 
Since V is the unknown, we solve for it;
12 = 
V = 12V
Answer: 24 hours
Explanation: One day is one rotation of the Earth, but it takes the earth 365 days to do one revolution or one year
I think the answer is strong force.
