Real-world examples of power
Paha777 [63]
By definition, power is the amount of energy consumed (or produced) in a second. (or more precisely, it is the rate of change in energy).
so anything which uses energy in a known time period can be labeled with a power rating.

an example for power could be a nuclear plant; traditional nuclear plants produce somewhat close to 1 giga watts (which means 1 giga joules in a second)

Rufina [12.5K]

Answer:

 N = 23.4 N

Explanation:

After reading that long sentence, let's solve the question

The contact force is the so-called normal in this case we can find it by writing the translational equilibrium equation for the y axis

            N - w₁ -w₂ =

            N = m₁ g + m₂ g

            N = g (m₁ + m₂)

let's calculate

            N = 9.8 (0.760 + 1.630)

            N = 23.4 N

This is the force of the support of the two blocks on the surface.

What happens when the temperature of the medium that sound is passing through increases?
MaRussiya [10]
Speed of sound through a medium depends on
● temperature
● density of medium
● speed of wind
● humidy
● moisture
Speed of sound increases with increase in temperature. Because when temperature increases the molecules get higher energy and they vibrate quickly. Due to this vibration sound waves can travel fastly.
