Answer:
2. 3.1415 m/s
3. 0.63m
4. 0.006 m/s^2
Explanation:
2. v=(2*pi*r))/T, put in values and solve.
3. Circumference=2*pi*radius, radius is 0.1m, plug in and solve.
4. a=(v^2)/r, (don't worry about converting to meters, since units are the same in kilometers, they will cancel out) plug in values and solve.
That's it!
<h3>Characteristics: </h3><h3>the length of the stem, battery savers, varied choices on how to clean it thoroughly, the battery replacements, a good sensitivity to heat, and precise readings are the basics that classify thermometers as good-working. </h3>
Answer:
he maximum frequency occurs when the denominator is minimum
f’= f₀ 
Explanation:
This is a doppler effect exercise, where the sound source is moving
f = fo 
when the source moves towards the observer
f ’=f_o 
Alexandrian source of the observer
the maximum frequency occurs when the denominator is minimum, for both it is the point of maximum approach of the two objects
f’= f₀
Their combined momentum after they meet is 0 .
