The speed of spaceship moving is 2.4 x 10^8 m/s
As from the given data, the clock in a spaceship is observed to run at a speed of 3/5 of a similar clock that rest on the earth is
T/T° = 3/5
The expression for the time dilation is given by
T = γT°
γ = T/T°
γ = 1/√1 - v^2/c^2 is time dilation
Substituting the values in the above equation as,
γ = T/T°
5/3 = 1/√1 - v^2/c^2
v^2/c^2 = 16/25
v = 0.8 c
v = 0.8 x 3 x 10^8 m/s
v = 2.4 x 10^8 m/s
Hence, speed of spaceship moving is 2.4 x 10^8 m/s

Answer:
333.46 J/g
Explanation:
To convert from kiloJoules per mole to kiloJoules per gram, first we convert to Joules per mole:
6.009 kJ/mol * 1000 = 6009 J/mol
1 mole of water contains 18.02 grams of water, hence:
(1 J/mol) / (1 mol) * (1 mol) / (18.02g)
Therefore:
(6009 J/mol) / (1 mol) * (1 mol) / (18.02g)
= 333.46 J/g
Another way of seeing this is, to convert from Joule per mole to Joules per gram, divide by the number of grams in one mole. In the case of water, it's 18.02 grams in one mole.

Answer:
Inductive reactance is 125.7 Ω
Explanation:
It is given that,
Inductance,
Voltage source, V = 15 volt
Frequency, f = 400 Hz
The inductive reactance of the circuit is equivalent to the impedance. It opposes the flow of electric current throughout the circuit. It is given by :
So, the inductive reactance is 125.7 Ω. Hence, this is the required solution.
False. It is more expensive to mine minerals in deep water deposits
