Answer:
2.67 m
Explanation:
We can write the proportion several ways. One of them is ...
(model to Jupiter)/(Jupiter distance) = (model to Pluto)/(Pluto distance)
(model to Jupiter)/5.27 = 20 m/39.5 . . . . . fill in the numbers
(model to Jupiter) = 20 m(5.27/39.5) ≈ 2.67 m
The model of Jupiter should be placed 2.67 meters from the sun.
I believe the correct answer from the choices listed above is option C. Electrons are both gained and <span>lost during a redox reaction. From the name itself "redox" or reduction-oxidation, it must be that something has reduced and another has gained that something.</span>
As the atmospheric pressure decreases, the temperature at which water boils decreases too. An increase in pressure leads to an increase in boiling point while a decrease in pressure leads to a decrease in boiling point.
Answer:
They both go backward because of force.
Explanation:
The logic behind this answer is that child right and pushes away causing her to go backward meaning her partner is being pushed backwards to.

*Answer:
Option A: 59.6
Explanation:
Step 1: Data given
Mass of aluminium = 4.00 kg
The applied emf = 5.00 V
watts = volts * amperes
Step 2: Calculate amperes
equivalent mass of aluminum = 27 / 3 = 9
mass of deposit = (equivalent mass x amperes x seconds) / 96500
4000 grams = (9* amperes * seconds) / 96500
amperes * seconds = 42888888.9
1 hour = 3600 seconds
amperes * hours = 42888888.9 / 3600 = 11913.6
amperes = 11913.6 / hours
Step 3: Calculate kilowatts
watts = 5 * 11913.6 / hours
watts = 59568 (per hour)
kilowatts = 59.6 (per hour)
The number of kilowatt-hours of electricity required to produce 4.00kg of aluminum from electrolysis of compounds from bauxite is 59.6 kWh when the applied emf is 5.00V
