False. C + O --> CO not CO2. Carbonmonoxide
Answer:
the easy way to describe this is to use a light as an example.
Explanation:
Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.
Answer:
Work done, W = 750 joules
Explanation:
It is given that,
Force acting on the object, F = 50 N
It moves to a distance of, d = 15 meters
We need to find the work done on an object. We know that the product of force and distance covered is called the work done. As the force and the displacement are in same direction. So,
W = 750 joules
So, the work done on an object is 750 joules. Hence, this is the required solution.
1790 = electrical energy / 2940 seconds
Electrical energy = 5262.6kJ
or
1.79kW X 49/60
= 1.46kWh
<span>Heat in a substance is still an example of heat
or thermal energy. Heat or thermal energy is further defined as the amount of
available molecules of kinetic energy transferred in a specific amount of time.
Heat is nothing if it is not transferred from one object to another. There are
many uses of heat energy. When we are cooking using our stoves, there is heat
energy. When we pour hot water onto our cup of coffee, there is heat energy.</span>
