Answer
Step 1
Toy 1 = 0.953
Toy 2 = 2.177
Step 2
Toy 1 = 953g
Toy 2 = 2177g
Explanation
Since we know that 1kg = 2.2026, if we divide 1kg by 2.2026, we get how much 1 pound is equal to. We then times that by the weight of the toy, and we get the weight in kg.
Toy 1
2.2046 lbs = 1 kg
2.1 lbs = ?
= 0.9525
To the nearest thousandth = 0.953
Toy 2
2.2046 lbs = 1 kg
4.7 lbs = ?
= 2.177
To the nearest thousandth = 2.177
Step 2
To convert kilograms to grams, we times the kg total by 1000, to get the mass in grams. (1kg = 1000g).
Toy 1
0.953 x 1000 = 953g
Toy 2
2.177 x 1000 = 2177g
Answer: 1.922x10⁻²⁰ Joules
Explanation: <u>Electric</u> <u>Potential</u> <u>Energy</u> (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.
<u>Voltage</u> or <u>Electric</u> <u>Potential</u> <u>Difference</u> (V) is external work done to move a charge from one point to another in a electric field.
These terms have a relationship, which is given by:
where
q is the charge
Proton is positive and has a charge of 1.6x10⁻¹⁹C.
Unit for potential energy is Joule (J). The relation between mV and J is
1mV = 10⁻³J
Then:
V = 120x10⁻³
V = 0.12
So, for a proton to move from the negative side of a membrane to the positive:
= 1.922 x 10⁻²⁰
Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.
