Explanation:
I'm not sure to be honest lol
Answer:d
Explanation:
Suppose V is the voltage of battery and R is the resistance of bulb
so Power drop for initial stage

When another identical bulb of same resistance is applied in parallel so voltage Drop across both the resistor will be same i.e. V
so Power consumed 
so there is no change in power and hence no dip in brightness
Since Power is equal to the product of Force and Displacement all over time, George needs 6.86 W of power to push the wheelbarrow. Power can also be calculated by multiplying Force applied on the object and the speed of the object being applied of the force.
Answer: The density of glycerine will be 
Explanation:
Density is defined as the mass contained per unit volume.

Given:
Density of glycerine= 
1 lbm = 0.454 kg
1 kg =
Thus 
Also 
Putting in the values we get:

Thus density of glycerine will be
