Answer:
Work done is 882000joule.
power is 29400watt.
Explanation:
given,
Mass(m)=500kg
Acceleration due to gravity(g)=9.8m/s²
Height(h)=6m
Time taken(t)=30s
Workdone=?
Power=?
now,
workdone=force*displaxement
= m*g*h
=500*9.8*6
=8,82,000joule
so, the work done by the man is 8,82,000joule.
then,
power=workdone/time taken
=8,82,000/30
=29,400watt
so, the required power to lift a load is 29,400watt.
I'm pretty sure there is only one element named after Mendeleev: <span>Mendelevium.</span>
2.3 grams of wood has the same energy as 1g of oil.
The majority of wood and wood waste used as fuel in the United States is used by industry. Manufacturers of paper and wood products are the biggest industrial users. They produce steam and electricity from waste from paper and lumber mills, which saves money by lowering the number of other fuels and electricity they need to buy to run their facilities.
There are numerous power plants that primarily burn wood to produce electricity in the electric power sector, and some coal-burning power plants burn wood chips along with coal to cut down on sulfur dioxide emissions. The primary purpose of wood consumption in the business sector is heating.

Answer:
350x
Explanation:
In a microscope the objective has higher magnification than the eyepiece so, this is a microscope
The magnification of a microscope is given by the product of the magnifications of the eyepiece and and the objective.
Objective lens magnification = 35x =
Eyepiece magnification = 10x =
Total magnification

Total magnification is 350x
