Answer:
my method is guessing it works 50% of the time :)
Explanation:
Explanation:
As we know that the maximum of thermal energy will be converted into mechanical energy.( The thermal energy will be given to us by engine.)
But the total thermal energy will not be converted into the mechanical energy, there will be some lost of energy. The lost of mechanical energy will be in multiple forms. 2 of them are
1.Heat : The mechanical energy heats up the engine and then it will lost some energy.
2.Noise : Some energy also lost in the sound or the noise comes out from the engine. It will consume some energy.
Also, the engine never be 100% efficient some amount of energy lost in environment also.
Answer:
Explanation:
= Actual wavelength = 
= Relative permittivity = 1.44
The observed wavelength in the glass is given by
The wavelength lies in the range of green light.
Hence, the observed color of light is
The percentage of mechanical energy of the oscillator lost in each cycle is 5.91 %.
The formula for mechanical energy in an oscillator is given by
E = 1/2 kA²
It is the sum of elastic potential energy and kinetic energy.
Amplitude is nothing but the maximum displacement moved by a point on vibrating body.
It is given that the amplitude A decreases by 3%, then
(E₂ - E₁) / E₁ = [1/2 k (A₂²- A₁²)] /(1/2 k A₁²) = (A₂²- A₁²)/ A₁² = (97² - 100²)/ 100²
⇒ 5.91% of the mechanical energy is lost in each cycle.

Answer:
As a body moving upward
T=real weight + apparent weight
T=550+490
T=1040
