Answer:

Power = 2940 Watts

Explanation:

Given the following data;

Mass = 60 kg

Height = 300 meters

Time = 1 minutes = 60 seconds

To find the power;

First of all, we would determine the potential energy possessed by the person due to height.

We know that acceleration due to gravity is equal to 9.8 m/s².

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

P.E = mgh

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the formula, we have;

P.E = 60 * 9.8 * 300

P.E = 176400

Next, we find the power using the following formula;

Power = energy/time

Power = 176400/60

Power = 2940 Watts

Natali5045456 [20]

Answer:

28.57 cm

Explanation:

We are given that

Focal length,f=50 cm

Distance of application from his eyes,s=40 cm

\frac{1}{s}+\frac{1}{s'}=\frac{1}{f}

\frac{1}{40}+\frac{1}{s'}=\frac{1}{50}

\frac{1}{s'}=\frac{1}{50}-\frac{1}{40}=\frac{4-5}{200}

s'=\frac{200}{-1}=-200 cm

s=25 cm

Substitute the values

\frac{1}{25}-\frac{1}{200}=\frac{1}{f'}

\frac{8-1}{200}=\frac{1}{f'}

\frac{1}{f'}=\frac{7}{200}

f'=\frac{200}{7}=28.57 cm
