Answer:
13.1
Explanation:
thats what i put in for acellus and its right
Energy is calculated as power*time, so give the wattage of 1200 W (equivalent to 1200 Joules/second) and time of 30 seconds, multiplying these gives 36000 J or 36 kJ of electrical energy.
If electrical charge or current is needed: Power = voltage * current, so given the power of 1200 watts and voltage of 120 V, current is 1200 W / 120 V = 10 Amperes. Charge is calculated by multiplying 10 A*30 s = 300 C.
Answer:e
Explanation:
Given
Size and Shape of two objects are same but have different mass
When they are dropped suppose from a height of h m
they reach the ground at the same time
velocity with which they reach ground is same because velocity is given by

But the momentum possessed by the heavier mass will be greater because Momentum is the Product of mass and velocity.
Velocity is same therefore mass will decide the magnitude of momentum .
