<span>6160 joules
to lift 1 newton 1 metre requires 1 joule
there are 10 newtons in one kilo
so 77(kg) x 8 (metres) x 10 (newtons/kilo) = 6160 joules</span>
Answer:
8 and 093 over 0.6 then 303
Explanation:
cross over the numbers and get the answer
Radiation therapy can used in treating and destroying tumors in the human body, but it can also cause long-term damage to tissues if used incorrectly.<span> Radiation can be used in X-rays to detect broken bones and other internal damages.</span>
Answer:
Advantages of Hydroelectric Energy
1 Renewable
Hydroelectric energy is renewable. This means that we cannot use up. However, there’s only a limited number of suitable reservoirs where hydroelectric power plants can be built and even less places where such projects are profitable.
2 Green
Generating electricity with hydro energy is not polluting itself. The only pollution occurs during the construction of these massive power plants.
3 Reliable
Hydroelectricity is very reliable energy. There are very little fluctuations in terms of the electric power that is being by the plants, unless a different output is desired. Countries that have large resources of hydropower use hydroelectricity as a base load energy source. As long as there is water in the magazines electricity can be generated.
4 Flexible
As previously mentioned, adjusting water flow and output of electricity is easy. At times where power consumption is low, water flow is reduced and the magazine levels are being conserved for times when the power consumption is high.
5 Safe
Compared to among others fossil fuels and nuclear energy, hydroelectricity is much safer. There is no fuel involved (other than water that is).
Voltage=Energy/Charge, V=E/Q
V in volts V, E in joules J, Q in coulombs C.
or
Voltage= Current×Resistance, V=IR
V in volts V, I in amperes A and R in ohms Ω
