Hello!

Remember that impulse is equivalent to:
Impulse = force (N) × time (s)
Plug in the given force and time:
Impulse = 25 × 32
Impulse = 800 Ns
You haven't told us the "wattage" rating of the bulb. We'll just have to call it ' W ' .
The bulb uses energy at the rate of W watts, or 0.001W kilowatts.
In 12 hours, it uses <em>0.012W kilowatt-hours </em>of energy.
= = = = =
W watts = W Joules/second
1 hour = 3600 seconds
12 hours = (12 x 3600) seconds
Energy = (W Joule/sec) x (12 x 3600 sec)
<em>Energy = 43,200W Joules</em>
Answer:
True
Explanation:
The mixing substances can be taken to be the reactants and the resulting mixture as the product. When the substances change state during mixing, the mass of the substances does not change meaning that the mass of the product will equal the mass of the reactants .This is true due to the law of conservation of mass.
