Answer:

Explanation:

Just use the Force formula.

F = M . A

Acceleration Formula

A = V - Vo / Time

So...

F = 845 . (30 - 2 / 0.9)

F = 845 . 20

F = 16900 N

Which statement best describes how the temperature of the oceans surface water varies
Setler79 [48]
<span>heat capacity→ water has a high heat capacity, and salt water has an even higher one, so the temperatures of the oceans remain within a small range because As the heat rises you get more evaporation which actually cools the ocean down (Specific Heat of Water; Heat needed to break down hydrogen bonds)</span>

g 2. The _____ spans the distance from the _____ to the location of the applied force. moment arm; pivot point moment of inertia
Alik [6]

Answer:

The correct answer to the following question will be Option A (moment arm; pivot point).

Explanation:

  • The moment arm seems to be the duration seen between joint as well as the force section trying to act mostly on the joint. Each joint that is already implicated in the workout seems to have a momentary arm.
  • The moment arm extends this same distance from either the pivot point to just the position of that same pressure exerted.
  • The pivotal point seems to be the technical indicators required to fully measure the appropriate demand trends alongside different time-frames.

The other three choices are not related to the given situation. So that option A is the appropriate choice.

Can an object have a low acceleration and high velocity at the same time . give example
LenaWriter [7]
Yes, acceleration only tells you how velocity is changing. It doesn't say anything about what velocity is at any given time.

For example, if you set your car to cruise control on the highway going 80 mph. That is a constant high velocity, yet the car has 0 acceleration.

The opposite is also true. After a red light turns green, you put foot on the gas to accelerate. However, your velocity is initially low even though it has high acceleration.
