How much work is required to lift a 2 kilogram mass to a height of 10 meters
Semmy [17]

Given mass = 2kg, height = 10m,g = 9.8.


We know that Work done W = FD


= > W = (mg)(D)


= > W = (2 * 9.8)(10)


= > W = 196 Joules.


Hope this helps!

relative to the floor, what potential energy does a 2.5 kg package have that sits on a shelf 2.2 m high
Kobotan [32]
Potential energy = mass x acceleration due to gravity x height
                             =    2.5 x 9.8 x 2.2
                             =          53.9 J.

Hope this helps!

Answer:

P = 24.32 W

Explanation:

The question is, "Two resistors 5 Ω and 10 Ω are connected in parallel with a 9 V power supply. Calculate the output power of the power supply.".

The voltage of the power supply, V = 9 V

Resistor 1, R₁ = 5 Ω

R₂ = 10 Ω

The equivalent of parallel combination of resistors is given by :

\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{R_{eq}}=\dfrac{1}{5}+\dfrac{1}{10}\\\\R_{eq}=3.33\ \Omega

The power of the output is given by :

P=\dfrac{V^2}{R_{eq}}\\\\=\dfrac{9^2}{3.33}\\\\P=24.32\ W

So, the output power is equal to 24.32 W.
