i would think by taking all the water out and storing it somewhere else and filtering it or cleaning it then put it back
You just give the acceleration a negative sign and do the the calculations.
Thunderstorms might form on warm days simply because heat is what causes evaporation, causing rain. Thunderstorms also form when the atmosphere is unstable! Meaning the hot air is above the cold air, evaporation occurs, it rains, and then rapid expansion of heat in the air caused by lighting causes thunder.
Because molecules in the air scatter blue light from the sun more than they scatter red light
The resultant of the forces is 29 N. Option D
<h3>What is the resultant force?</h3>
The resultant force is the force that acts in a given direction. Now we have two forces as enumerated in the question.
Thus;
Resultant = √(10)^2 + (20)^2 - [2 * 10 * 20 * cos (60 - 30))
Resultant = 29 N
Thus, the resultant of the forces is 29 N.
