Answer:
12 m/s
Explanation:
English Translation
At what maximum speed is the cyclist traveling for a short time if he has a maximum power of 420W and at this speed he must overcome the resistance 35N.
The Power, P, expended by a moving body with velocity, v, moving against a resistive force of F is given as
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s
In Polish/Po polsku
Moc P, wydana przez poruszające się ciało z prędkością v, poruszająca się przeciw sile oporu F, jest podana jako
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s

Answer:
The density of Saturn is 686.81 kg/m³.
Explanation:
Mass of Saturn, 
Volume of Saturn, 
Density of Saturn is given by its mass divided by its volume i.e.
So, the density of Saturn is 686.81 kg/m³.
The density of water is 1000 kg/m³. It is clear that the density of Saturn is less than water.
True! they're the lowest in mass of all parts of the atom
Answer:
Conditions under which the belt and pulleys are operating – The friction between the belt and pulley may decrease substantially if the belt happens to be muddy or wet, as it may act as a lubricant between the surfaces.

Answer:
The process of producing electric energy or the amount of electric energy produced by transforming other forms of energy into electrical energy; commonly expressed in kilowatt-hours (kWh) or megawatt-hours (MWh). Electric power plant efficiency η is defined as the ratio between the useful electricity output from the generating unit, in a specific time, and the energy value of the energy source supplied to the unit in the same time period. For electricity generation based on steam turbines 65% of all prime energy is wasted as heat. The maximum theoretical energy efficiency is defined in more detail by the Rankine cycle. For modern practical systems this is about 40% but less for older generating plant. The efficiency falls still further if fuels with lower energy content such as biomass are used to supply the plant. The economics of power generation based on reciprocating engines depends to a large extent on the use to which the engine is to be put. The cheapest engines available are small petrol-driven engines based on car engines, which are manufactured in large numbers each year.
