Answer:
18.896ms-1
Explanation:
The tangential acceleration of the car= 0.747ms-2
The centripetal acceleration is given by v^2/r
0.747= v^2/r
V= √0.747*478= 18.896ms-1
Answer:
12294.31 m/s
Explanation:
Momentum = (mass)(velocity)
Momentum before = Momentum after
(momentum of bullet)+(momentum of block)=(momentum of bullet and block)
0.035v+50(0)=(0.035+50)(8.6)
0.035v=430.301
v=12294.3142857m/s
Illluminance is the measurement of photometric power. That means, illuminance is the rate of photometric flux that is received by a surface per area. It is usually expressed as a unit of W/m^2.
Thus, from the choices, the answer we're looking for is illuminance<span>.</span>

Explanation:
Convection is a type of process where heat travels upwards and cold travels downwards.
Answer:
True
Explanation:
Standard heat of formation is the heat change that deals with the formation of 1mole at standard rates and states of the given reactants . Standard heat of formation is the difference between the enthalpy change of reactants and products.
