Answer: the drink cooled down to the same temperature as the room it was in.
Explanation: due to the change and temperature of the room, it cause the heat particles to exchange, causing it cool
I think the answer is mass
Answer:
I think it's because the refractive index of that medium is constant
Answer:
average speed = 1.73m/s
average velocity = 3.33m/s
Explanation:
<em>we'll</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>average</em><em> </em><em>speed</em><em> </em><em>first</em>
<em>average</em><em> </em><em>speed</em><em> </em><em>=</em><em> </em><em>total</em><em> </em><em>distance</em><em> </em><em>/</em><em> </em><em>total</em><em> </em><em>time</em><em> </em>
<em>his</em><em> </em><em>total</em><em> </em><em>distance</em><em> </em><em>is</em><em> </em>300m + 100m
= 400m
and total time should be taken in seconds as you know
((2×60)+50) + 60s
= 230s
so let's divide,
400m/230s
1.73 m/s
next, mean velocity
that is,
mean velocity = final- initial displacement/time
we have to note <em>displacement</em><em> </em>( this is the distance between the initial point to final point) here
the displacement is 300-100
so, 200m
we already calculated total time
but that cant be taken here
230 - 170
is the original time to travel 200m
that is, 60s
so we divide
200/60
3.33m/s
Hi sorry
I don’t know sorry
but maybe next time
