The energy required is 30 watts second.
In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or eliminated.
The voltage of a battery is 12 V and;
The charge is 2.5C.
Now, energy can be defined as the product of voltage and charge.
Therefore,
E = V × C
E = 12 × 2.5
E = 30 watt second
Hence, the energy needed by the 12 V battery to move 2.5 C through the electrical circuit is 30 watts second.

So if the sandwiches cost $7.75 each and the total was $113.50 that would mean that there were 14 sandwiches bought. So 14 times 7.75 is 108.50.
You just combine like terms so it'll be 5x^43
Answer:
11/4 or , 2 3/4
Step-by-step explanation:
I don't like math so I am not going to call it fun, but these problems are super easy for me, so it almost IS fun.
4/4 = 2/2 because they are both wholes.
2/4 = 1/2 because they are both halves.
Now, if we split one of the numbers down, we will get one of these.
6 1/4
6 x 4 because there are 6 wholes...= 24
then 24 plus 1 because there is still one fourth...=25
25/4
Now, 3 1/2 pounds.
Lets change it to fourths. 3 2/4
Now, 3 x 4, 12, then 12 plus 2 equals 14/4
Now compare your numbers.
