The speed of the cart after 3 seconds of Low fan speed is (2) cm/s. This is further explained below.
<h3>What is speed?</h3>
Generally, speed is simply defined as the rapidity of movement or efficiency of operation.
In conclusion, After 8 seconds with the fan set at Low, the cart will have traveled 1 cm/s. After three seconds at medium fan speed, the cart travels at a velocity of two centimeters per second.

Explanation:
Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. ... Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you add calcium chloride to water, the solution heats.
Answer:
Explanation:
Given:
- pressure on the piston,
- diameter of the piston,
- displacement of the piston,
- time taken in the piston displacement,
<u>Now, we find the force on the piston:</u>
where, A = area upon which pressure acts
<u>we know that Power is given as:</u>
( 8.10) x 10^4 J = ½(1010kg)V²
<span>......................= 505V² </span>
<span>( 8.10) x 10^4 J =[(.0505) x 10^4] V² ........<==10^4 cancels </span>
<span>8.10 = .0505 V² </span>
<span>.........______ </span>
<span>V = ²√ 160.4 </span>
<span>V= 12.6 m/s </span>
<span>(that's 12.6m/sec(1km/1000m)(3600secs/1hr) = 45.36kph) </span>
<span> my diagram is wrong, it is just an ordinary car, </span>
The bulk of earths atmospheric oxygen comes from phytoplankton, small flower like things in the ocean.
