Answer:
77000 J
Explanation:
Formula for the heat energy is;
Q = m•c•Δt
We are given;
mass; m = 2 kg
Change in temperature; Δt = 110 - 10 = 100 °C
From online values, specific heat capacity of copper is; c = 385 J/kg.°C
Thus;
Q = 2 × 100 × 385
Q = 77000 J
Answer:
A combined wave of extra height will produce every other wave.
Explanation:
One wave Crest can catch up to another wave Crest if the group of waves are from different places.
Here the two group of waves have different wavelength but travelling together in the same direction so when they combine,they will produce every other wave.
Answer:
The maximum torque is 
Explanation:
From the question we are told that
The length of the wire is 
The current flowing through the wire is 
The magnetic field is 
The maximum torque is mathematically evaluated as
Where 
is the magnetic dipole moment which is mathematically represented as
Where 
is the number of turns which from the question is 1
substituting values
Now
-- If you're observing the moon from a location in the northern hemisphere, like Canada, Russia, the US, or Israel, then it looks like this picture during the <em>waxing crescent</em> phase.
-- If you're observing the moon from a location in the <u>southern</u> hemisphere, like Australia, South Africa, Paraguay, or Antarctica, then it looks like this picture during the <u>waning</u> crescent phase.
