Answer:
D) 0.32
Explanation:
The computation of the thermal efficiency is given below:
Thermal efficiency is
= 710 J ÷ (710 J + 1480 J)
= 710 J ÷ 2,190 J
= 0.32
Hence, the thermal efficiency is 0.32
Therefore the last option is correct
Answer
given,
mass of the = m₁ = 8.75 Kg
another mass of the object = m₂ = 14 Kg
distance between them = 50 cm
R₁ = 17 cm
R₂ = 50 -17 = 33 cm
a) Force applied due to the Mass 8.75 in +ve x- direction



Force applied due to mass 14 Kg in -ve x-direction



net force
F = F₁ + F₂


Using newton second law



b) As the acceleration of mass comes out to be +ve hence, the direction will be toward the mass of 8.75 Kg
It definitely changes in frequency. For example if the frequency is medium the signals change after the sunset and it changes in the ionosphere cause medium frequency travels in the skywave.
Answer:
i think firest one is true
and the second one is D
Evaporation, or turning liquid to a gas, is first. Then it goes into the atmosphere and codensates, or turns back to a liquid, these water droplets form into clouds and come down as precipitation, rain, sleet, snow etc. Then the water cycle starts again
