Answer:
372,400 N
Explanation:
The volume of the column is ...
V = Bh = (2 m^2)(19 m) = 38 m^3
If we assume the density is 1000 kg/m^3, then the mass of the water is ...
M = ρV = (1000 kg/m^3)(38 m^3) = 38,000 kg
The force of gravity on that mass is ...
F = Mg = (38,000 kg)(9.8 m/s^2) = 372,400 N
Answer:
It is usually the GPU and the CPU in that order. The most you really need to consider is looking at the specs of the parts and add up the wattage. Add 100 Watts to it to be safe and it should be fine. Just purchase a PSU with a 100 watt extra leeway for the pc, which is a negligable price difference.
Answer:
They fell at the same time.
Explanation:
Galileo was the first to discover the property of gravity, in which it makes everything fall at the same time in an airtight space. Gravity makes all objects fall and accelerate at 9.8m/s/s, regardless of weight, because the ratio between the weight of the object and the air resistance acting against it is a constant.
Answer:
33,333.3J/s
Explanation:
Energy expended which is the work done in Joule
=250,000J
Time taken to expend the energy =7.5s
Power =Unknown
Formula
Power = <u> </u><u> </u><u> </u><u> </u><u> </u><u>Work</u><u> </u><u> </u><u> </u>
Time
Hence, Power = <u>250,000J</u>
7.5s
Power = 33,333.3J/s
False it <span>the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.</span>
