N=N₀*2^(-t/T)
N₀=200 g
T=10 d
t=30 d
N=200*2^(-30/10)=25 g
25 g will remain
Answer:.633

Answer : The disadvantage of using hydropower is Land can be flooded, displacing people and wildlife
Explanation :
Hydropower is a renewable source of energy. In hydropower, electricity is generated using the mechanical energy of moving water.
Since the kinetic energy is necessary to move the turbines, it is essential that the hydropower plant is present near a water source which has moving water.
It is the most efficient way of harnessing the energy from naturally available energy sources. It does not produce any waste. It does not pollute water or air.
Since hydropower needs kinetic energy of moving water, there is always a possibility of nearby land getting flooded. This would affect the people and wildlife of nearby areas.
Therefore the disadvantage of using hydropower is that land can be flooded, displacing people and wildlife
1500 mm of copper wire are produced by converting 150 cm of copper wire.
The following is the centimeter to millimeter conversion factor: 1 cm is equivalent to 10 mm.
Consequently, 150 cm will equal 150 x 10 = 1500 mm.
- The multi-step process of unit conversion involves multiplying or dividing by a numerical factor.
- Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
- Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor.
- The process may also require the selection of the correct number of significant digits, and rounding.
