state the principle of superposition
how longitudinal waves reflect and refract?
A Carnot engine has an efficiency of 0.5 while working between a source at 400K and a sink at TK. The temperatures of both the source and the sink are changed. Calculate the efficiencies of the engine when temperatures are (a) increased by 100°C and (b) decreased by 100°C. Interpret your result physically.
The velocity of a particle is v=5+2 (a1+a2t) where a1and a2 are constants and t is the time. What is the eccelaration oif the particle.
On a vehicle crash simulation, a car of mass 1200 kg is travelling at a velocity of 40 mph in the easterly direction when it is hit by a truck of mass 3300 kg travelling at a velocity of 25 mph from the westerly direction. Assuming that the two vehicles become entangled calculate in m/s their combined velocity after the crash.
Take 1.61 km/hr = 1 mph
a car starts from rest and attains a velocity of 18 km/h in 2 sec find it accerleration in S.I unit
a centripetal accereration vector points _ of a circle
away from the center
toward the center
tangent to the arc
none of these
a car turns a corner at 10mph. If it were to turn the corner at 30 mph, the centripetal acceleration would be ___
nine times larger
three times larger
one third as large
one ninth as large
as an object falls__________
both velocity and acceleration increase
velocity increases and acceleration decreases
velocity increases and accerlation is unchanged
both velocity and acceleration remain unchanged
match.
ratio of work output to work input work
product of mass and velocity gravity
spent energy velocity
weight efficiency
rate of change of displacement power
rate at which work is done momentum
