Answer:
i guess it will be mass or volume, but not sure
Explanation:
because the blocks volume will be same as the displaced water, then u will check the mass or volume of the water to see what the volume of a object will be.
Answer:
1Kilowatt =1000watts
Now
Energy =Power x time
We need our power in Kilowatt and Our time in hours
Given
Power = 1200Watt
Divide this by 1000... To get its value in Kilowatt
Power = 1.2kilowatt
Time=6min
Divide by 60 to get its value in hours
Time = 6/60hr = 0.1hrs
Energy = 1.2kilowatt x 0.1hrs
=0.12kilowatt hours
Explanation:
Using,
S = vi*t + 1/2*a*tr^2
vi = initial velocity = 0 m/s
S = 1/2 * 9.8 * tr^2
= 4.9tr^2.
S = vf * (ta - tr)
4.9tr^2 = 330 * (9.3 - tr)
4.9tr^2 - 3069 + 300 * tr)
Using general quadratic equation,
tr = 8.93 s.
S = 4.9 * (8.93)
= 390.75 m.
B.
Therefore,
S = 4.9 * (9.3)^2
= 423.8 m.
The height of the cliff would be overestimated.
Answer:
Fossil fuels have been used for centuries to generate power, but there are many disadvantages associated with their use:
Fossil fuels pollute the environment.
Fossil fuels are non-renewable and unsustainable.
Drilling for fossil fuels is a dangerous process.

The wavelength will chang along with the frequency, I think. I don't recall why it would lose energy...
