Answer:
333 N
Explanation:
The weight of an object is given by:

where
m is the mass of the object
g is the acceleration of gravity
For the mower in the problem,
m = 34 kg
Also

So, the weight of the mower is

Answer:
The answer is 2,500 * 45 = 112500kgm/s
Answer:
Therefore energy is stored in the 1.0 mF capacitor is 5.56×10⁻⁹ J
Explanation:
Series capacitor: The ending point of a capacitor is the starting point of other capacitor.
If C₁ and C₂ are connected in series then the equivalent capacitance is C.
where 
Given that,
C₁ = 1.0 mF=1.0×10⁻³F and C₂ = 0.50mF=0.50×10⁻³F
If C is equivalent capacitance.
Then 

mF
Again given that the system is connected to a 100-v battery.
We know that
q=Cv
q= charge
C= capacitor
v= potential difference
Therefore


The electrical potential energy stored in a capacitor can be expressed

q= charge
c=capacitance of a capacitor
Therefore energy is stored in the 1.0 mF capacitor is


J
Hydro power, although a low-cost option, is not implemented every time because of the amount of disadvantages there are. One of the disadvantages this has is the pollution is gives. Since the reservoir is always filled with water, this causes any surrounding plants and trees to decompose, releasing a huge amount of methane and carbon dioxide into the environment. Aside from this, it also destroys nearby habitats, and diverts natural waterways, effectively killing fishes too.
