OK.

But first we need to know . . .

-- Where is Riverdale ?

-- What is the air temperature there right now ?

-- What kind of system is being used now ?

-- Where can we get a complete description of the groundwater system ?

Can a average velocity be zero.Why? ​
marishachu [46]

<u>Answer:</u>

Yes

<u>Explanation:</u>

Average velocity is the ratio of total displacement and time taken for that displacement:

average \space\ velocity = \frac{displacement}{time}

This means if displacement is zero, then average velocity will also be zero.

Displacement is zero when an object moves some distance in one direction, and then moves the same distance but in the opposite direction.

∴ As it is possible for displacement to be zero, it is also possible for average velocity to be zero.

A 0.15 kg baseball is hit by a baseball bat. Right before it is hit, the ball’s speed is 30 m/s, and right after it is hit, the
Roman55 [17]

Answer:

Impulse will be 12 kgm/sec

So option (b) will be correct option

Explanation:

We have given mass of the baseball m = 0.15 kg

Ball speed before hit v_1=30m/sec

Ball speed after hitting  v_2=-50m/sec ( negative direction due to opposite direction )

We have to find the impulse

We know that impulse is equal; to the change in momentum

So change in momentum = m(v_1-v_2)=0.15(30-(-50))=0.15\times 80=12kgm/sec

So option (b) will be correct option

Frank wrote several statements to summarize the relationship between the first and second laws of thermodynamics.
Kaylis [27]
First law is Conservation of Energy

Second is that entropy of an isolated system will always increase with time.

Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature
