Suman climb a 5 metre high ladder in 10 second calculate his power the mass of his body is 50 kg​
nadezda [96]

Answer:

245W

Explanation:

Given parameters:

Mass of his body = 50kg

Height of climb  = 5m

Time  = 10s

Unknown:

Power = ?

Solution:

Power is defined as the rate at which work is done;

 Mathematically,

           Power  = \frac{work done}{time}

  Work done  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

  Work done  = 50 x 9.8 x 5  = 2450J

 

          Power  = \frac{2450}{10}   = 245W

How would you obtain a mean value for the specific heat<br> capacity of a material?
lidiya [134]
The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT. Values of specific heat are dependent on the properties and phase of a given substance.
