Answer:
#2) The spaceship's forward motion must be slowed down so the earth's gravitational pull on it will be stronger than the ship's forward motion.
Answer:
Explanation:
1 foot = 12 inches
Sammy is 5 feet tall.
5 feet = ? inches
Multiply the feet value by 12 to find in inches.
5 × 12
= 60
Add 5.3 inches to 60 inches.
60 + 5.3
= 65.3
The mass on the left has a downslope weight of
W1 = 3.5kg * 9.8m/s² * sin35º = 19.7 N
The mass on the right has a downslope weight of
W2 = 8kg * 9.8m/s² * sin35º = 45.0 N
The net is 25.3 N pulling downslope to the right.
(a) Therefore we need 25.3 N of friction force.
Ff = 25.3 N = µ(m1 + m2)gcosΘ = µ * 11.5kg * 9.8m/s² * cos35º
25.3N = µ * 92.3 N
µ = 0.274
(b) total mass is 11.5 kg, and the net force is 25.3 N, so
acceleration a = F / m = 25.3N / 11.5kg = 2.2 m/s²
tension T = 8kg * (9.8sin35 - 2.2)m/s² = 27 N
Check: T = 3.5kg * (9.8sin35 + 2.2)m/s² = 27 N √
hope this helps. :)
Some types of storage tanks are exempt from the federal regulations on USTs, including
: A) tanks that store heating oil burned on the premises.
<h3>What are Underground Storage Tank Systems?</h3>
Underground Storage Tank systems are tanks along with the underground piping that has at least 10% of their total volume underground.
Some of the storage tanks that are exempt from the federal regulations on USTs are;
- Farm and residential tanks of 1,100 gallons or less capacity holding motor fuel used for noncommercial purposes.
- Tanks storing heating oil used on the premises where it is stored.
- Tanks of 110 gallons or less capacity.

It is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game.
<h3>
What is a motor crash?</h3>
A motor crash is the event in which a motor vehicle is involved in a collision amongst another motor vehicle, pedestrian, animal, or stationary object.
<h3>Impact of motor crash</h3>
A motor crash can cause the following;
- total damage of the car
- breaking of bones of the driver
- damage of properties colliding with the car
Thus, it is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game. In the video game he will not be involved physically with the motor crash.
