Hi, thank you for posting your question here at Brainly.
For consistency you must convert gallons to cubic foot. The conversions are:
7.481 gal = 1 ft3
Then, $3.65 per gallon becomes $27.3 per ft3. If you buy $40 worth of gas, you get $40/$27.3 = 1.46 ft3 of gas.
If you can travel for 4 miles per ft3, then with the amount of gas you have, you can travel up to 5.85 miles.
(4 miles/ft3)*(1.46 ft3) = 5.85 miles
If the field strength between the plates is 9 volts per cm, then over a path of 1/2cm parallel to the field, the potential changes by (1/2) x (9 volts) = 4.5 volts.
Answer:
.05
Explanation:
wavelength/frequency = wave speed
45 = 2.5/x
x = 0.05
Answer:
The extent of greenhouse effect on mars is
Explanation:
From the question we are told that
The albedo value of Mars is 
The albedo value of Mars is 
The surface temperature of Mars is 
The surface temperature of Venus is 
The distance of Mars from the sun is 
The distance of Venus from sun is 
The radius of the sun is 
The energy flux is 
The solar constant for Mars is mathematically represented as
![T = [\frac{E R^2 (1- A_1)}{\sigma d_m} ]](https://tex.z-dn.net/?f=T%20%3D%20%5B%5Cfrac%7BE%20R%5E2%20%281-%20A_1%29%7D%7B%5Csigma%20d_m%7D%20%5D)
Where
is the Stefan's constant with a value 
So substituting values


So the greenhouse effect on Mars is
