The change in temperature is simply 50 / (9/5) = 27.777. We just throw out the 32 from the formula
Answer:
Adsorption
Explanation:
Sidewalk cooking of egg is very popular in America. In summer people release fireworks in night sky and cook egg on the concrete sidewalk to check the level of temperature. When sunlight fall on the sidewalk most of the light is reflected back but some darker material adsorbs some photon, and when these photons are transferred to egg molecules it causes vibration among them and produce heat and cook egg.
Answer:
option D
Explanation:
given,
coefficient of friction between wall and tire = µ
speed of motorcycle = s
friction force = f = μ N
where normal force will be equal to centripetal force
for motorcycle to not to slip weight should equal to the centripetal force
now,
where "rg" is constant
Hence, the correct answer is option D
