Question is missing:
"What is the gravitational force between the Sun and Jupiter?"
Answer:

Explanation:
The gravitational force between two objects is given by

where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between the objects
In this problem, we have
is the mass of the sun
is the mass of Jupiter
is their separation
Solving the equation, we find

evaporation (if that's to fill in the blanks question)
Answer:
A turbine and generator produce the electricity
Explanation:
"A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
Answer:
1.5 unit of product per min
Explanation:
30 units of product was moved in 30 minutes.
Number of units left = Total number of units-number of units moved
=75-30 =45 units
45 units is available to be moved for the rest 30 min. To be able to achieve this goal of 75 units of product per hour.
45/30 amount of units must be moved in 1 min
=1.5 unit per min
Answer:
42KVA
Explanation:
Given data
High Voltage (HV)= 480V
Low Voltage (LV)= 277V
Fo find
Size of transformer=?
Solution
To find the size of transformer here we use the co-ratio.The Co-ratio is given as:
Co-Ratio= (HV - LV)/HV
where
HV is High Voltage
LV is Low Voltage
Now put the values we get
Co- Ratio=(480-277)/480=.42
So the size of transformer is 42KVA
