If that statement is true, then NO motionless object could EVER start moving.

Yet I've seen several that did.  So it must be <em>false</em> .

__________ helps us adapt to our environment. It also generally __________ with age. A. Plasticity . . . decreases B. Developmen
Nana76 [90]
Not sure this is a physics question (probably biology).
Anyway, the correct answer is A):
"Plasticity helps us to adapt to our environment. It also generally decreases with age".
Plasticity is the ability to adapt to the environment. Since this ability is linked with brain functions, and brain functions worsen with age, then plasticity decreases with age.

Electric power is to be generated by installing a hydraulic turbine-generator at a site 120 m below the free surface of a large
iogann1982 [59]

Answer:

P = 2234400 Watt

Explanation:

Power generation is given as rate of work done

Here the turbine generator is located at 120 m below the free surface

So here rate of work done is given as rate of potential energy

Power = \frac{dw}{dt}

Power = \frac{mgh}{t}

so we have

Power = (\frac{dm}{dt})gh

now we have

Power = 1900(9.8)(120) = 2234400 Watt

so the power generation potential will be 2234400 Watt

A 15kg ball accelerates at a rate of 3m/s/s. What force was required?
hoa [83]

Answer:

<h2>45 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 15 × 3

We have the final answer as

<h3>45 N</h3>

Hope this helps you
