Answer:
or 11616
Explanation:
Since there are 5280 feet in 1 mile
you do 2.2 × 5280
2.2 × 5280 = 11616
Its average speed is 80 miles per hour because 75 minutes=1.25 hours, and the police car travels 80 miles in 1.25 hours, so I just need to take 100 divided 1.25 equal 80. As a result, the police car travels 80 miles in one hour. Hope it help!
Answer:
deep, fertile soils. not too dry and not too wet. warm climate. land suitable for machinery.

Answer:
height = 45 m
Explanation:
Initial velocity = 0 m/s
Final velocity = 30 m/s
Acceleration due to gravity = +10m/s^2 ( because ball is going down )
Using the eqn of motion
where v= final velocity ; u = initial velocity ; g = acceleration due to gravity ; h = height
So,
Answer: The elevator must be accelerating.
Explanation:
As the tension force is opposing to the the force of gravity on the load which is hung vertically, and the tension force can adopt any value in order to comply with Newton's 2nd law, if the tension force is less than the force due to gravity, this means that all system is not in equilibrium, so it must be accelerating.
If we assume that the downward is the positive direction, we can write:
mg - T = ma
If T = 0.9 mg, ⇒ mg (1-0.9) =0.1 mg = m a ⇒a = 0.1 g , in downward direction.
