Answer:
The answer to your question is: 10.48 km/s
Explanation:
Data
h = 5.6 x 10⁶ m
g = 9.8 m/s²
Formula
vf = 
Substitution
vf = 
vf = 
vf = 10476.64 m/s
convert to km/s
vf = 10476.64/1000
vf = 10.48 km/s
Answer:
Point A (Maximum height)
Explanation:
Potential energy is given as the product of mass, height and acceleration due to gravity hence expressed as mgh where m is the mass of roller coaster, h is the height and g is acceleration due to gravity. Since the mass and g are constant for a roller coaster, the main factor that will influence the magnitude of energy is the height. The higher the height, the higher the potential energy and vice versa. Using the attached image, the highest point is point A
Answer:
The distance spring compresses (x) = 0.0811 m
Explanation:
Spring constant (k) = 185 N / m
mass (m) = 1.53 kg
When mass is placed upon the spring the spring force is equal to weight of the mass.
⇒ Spring force (F) = weight of object
⇒ Spring force (F) = k × x
And weight of the object = mg
⇒ k x = mg -----------------(1)
Put all the values in equation (1) we get
⇒ 185 × x = 1.53 × 9.81
⇒ x = 0.0811 m
This the distance spring compresses, when mass is placed upon it.
The second answer choice is not true (ozone is concentrated in the stratosphere, not the exosphere)
