Answer:
20000 pounds
Explanation:
Generally 1 gallon of fuel burnt gives of 20 pounds of CO₂
Difference in the gallons of fuel burnt
The 20 mpg car burns 1000 gallons of fuel more than the 30 mpg car
The amount of CO₂ would be
The fewer pounds that the 30 mpg car would release is 20000 pounds
Answer:
C 3.3 s
Explanation:
Given:
Δy = 9 m
v₀ = 0 m/s
a = ⅙ (9.8 m/s²) = 1.63 m/s²
Find: t
Δy = v₀ t + ½ at²
9 m = (0 m/s) t + ½ (1.63 m/s²) t²
t = 3.3 s
Friction, wind resistance, gravity, tension force
Answer:
Saturn is B, Neptune is D, Jupiter is A, and Uranus is C
Explanation:
Each one is different and if you do some research on each planet the question is not that hard.
Answer:
x(spring stretch)=1.74×10⁻³ meter
Explanation:
Given Data
l (length)=0.175 m
v (speed)= 3.86 m/s
x₁(stretch)=0.0140 m
x(spring stretch)=?
Solution
Centripetal force=Spring Constant
as
Spring force = gravitational force
