An athlete with a mass of 65.5 kg is in a cross country race, and at one instant he has a speed of 4.20 m/s. (a) What is his kin

lions [1.4K]

Answer:

(A) Kinetic energy will be 577.7 j

(b) Factor by which kinetic energy will change is 4

Explanation:

We have given mass of the athlete m = 65.5 kg

He has a speed of 4.20 m/sec

So v = 4.20 m/sec

(a) Kinetic energy is given by $KE_i=\frac{1}{2}mv^2=\frac{1}{2}\times 65.5\times 4.20^2=577.71J$

(B) Now he wishes to doubles his speed So now speed = 4.20×2 = 8.40 m/sec

Now kinetic energy is $KE_f=\frac{1}{2}mv^2=\frac{1}{2}\times 65.5\times 8.40^2=2310.84j$

So the factor by which kinetic energy will change $=\frac{KE_F}{KE_I}=\frac{2310.84}{577.7}=4$

What kind of funnel is used with vacuum filtration? question 5 options:

shutvik [7]

The correct answer is option (d) Buchner funnels

In the lab, Buchner funnels are used for vacuum-assisted liquid filtration. These funnels are employed in organic chemistry to collect recrystallized molecules since they aid in drying out the final product.

What is Buchner funnels?

For the vacuum-assisted filtering and separation of liquid substances, commercial labs employ Buchner Funnels, fritted/perforated funnels.
Using a vacuum pump and Buchner funnels, you can filter liquids by forcing them through high-quality filter paper and holes at the top of the funnel.
Only flat-surfaced funnels, like the Hirsch or Büchner funnels, which are both composed of porcelain, may be used for vacuum filtrations. The filter paper must completely enclose the funnel's bottom perforations; it may not protrude over the sides.
