The <em><u>gravity on the Earth</u></em> has acceleration is smallest in magnitude
Given:
- Acceleration from 0 to 30 m/s in 2 s
- Deceleration from 30 m/s to 10 m/s in 1.5 s
- Gravity on Earth
To find:
The accelerations with the smallest magnitude
Solution:
- Acceleration from 0 to 30 m/s in 2 s
The acceleration in 2 seconds:
The magnitude of the acceleration is 15.
- Deceleration from 30 m/s to 10 m/s in 1.5 s
The deceleration in 1.5 seconds:
The magnitude of the deceleration is 13.4.
The value of the acceleration due to gravity =
The magnitude of the acceleration is 9.8.
9.8 < 13.4 < 15
The <em><u>gravity on the Earth</u></em> has acceleration is smallest in magnitude.

Answer:
D ) Elastic and Gravitational
Explanation:
Mechanical energy is defined as the sum of elastic, potential and kinetic energies.
Therefore potential energy and gravitational or potential energy are contemplated within the definition of mechanical energy.
The units for energy are given in joules [J] for the SI and Btu for the IP system
Answer:
The correct answer is C.) Static Friction > Sliding Friction
Explanation:
Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases. Hope this helps!

Answer:
36 months or 36,000 miles
Explanation:
CNG cylinder has limited lifespan. Generally lifespan of CNG cylinder is 15 years to 20 years. For safety purpose these cylinder should be inspected timely. Time limit for inspection of CNG cylinder is 36 months or 36,000 miles whichever comes first.
ThusCng cylinders must be inspected at least every 36 months or 36000 miles.
