Answer:vapour gets stuckes into the carburetor when the car engine heat up with continuous acceleration and deceleration.
Explanation:Vapor lock occurs when the car engine gets heat up with continuous acceleration and deceleration. The automobile engine has to work harder during the hot summer days. An automobile engine runs hotter than usual in the stop-go traffic.. This extreme heat vaporizes the fuel in carburetor and fuel pump.
Answer:
h =12.9 w/m2 k
Explanation:
we know that thermal conductivity of air K at 0 degree celcius = 0.024 w/mk
T_S = 80 Degree celcius
temperature gradient = -43 degree C/mm = - 43*1000 / m
by fourier law


q = 1032 watt/m2
we know that from newton's law
q = h (T_s - T_∞)
1032 = h*(80 - 0)
h =12.9 w/m2 k
Answer:
50km/hr is the velocity of a car that traveled a total of 75 km North in 1.5 hours.
From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s
