Answer:
F= G m₁m₂/r²
a. F is directly proportional to the masses so any increase in the masses will increase the Force F and vice versa.
b. F is inversely proportional to the square of the distance between the masses so any increase in the distance will decrease the force F and vice versa.
c. G is a gravitational constant and is expressed in Nm²/kg². this will give force in Newtons
Answer:
Car 1 : 40 miles per gallon
Car 2: 25 miles per gallon
Step-by-step explanation:
family has two cars. During one particular week, the first car consumed 15 gallons of gas. The second car consumed 25 gallons of gas. The two cars Drove a combined total of 1475 miles and the sum of their fuel efficiency was 65 miles per gallon. What were the fuel efficiency of each of the cars that week
Given that :
Fuel efficiency , car 1 = x
Fuel efficiency , car 2 = y
x + y = 65 - - (1)
15x + 35y = 1475 - - - (2)
x = 65 - y
15(65-y) + 35y
975 - 15y + 35y = 1475
20y = 14875 - 975
20y = 500
y = 25
Put y = 25 in (1)
x + y = 65
x + 25 = 65
x = 65 - 25
x = 40
Compare centers mean you need to compare the median of the two box plots.
Box 1: Median (Q2) = 40
Box 2: Median (Q2 is between 40 and 50 (40 < Q2 < 50)
So the center of box 2 is greater than center of box 1
Hope it helps.
The third equation is the correct one. After 100 years, about 115 grams will remain.
