Look at photo D. Explain how the fountains help to keep the gardens cool. ​

Physics

Anton [14]3 years ago

Answer with Explanation:

Spain is known to have <em>hot summers</em>, thus, it is very easy for water to evaporate once exposed to<u> direct heat source</u> (such as the sun).

A fountain is being used in order to keep the garden's surrounding air temperature low by allowing the<u><em> evaporation of water</em></u><u>.</u> One factor that speeds up the evaporation of water is the<u> surface area</u>. The water coming out of a fountain is in small quantities; however, it meets up with hot air in a<em> large surface area.</em> This allows faster evaporation, leading to an even <em>greater cooling effect because heat is being transported immediately from the liquid state to the gaseous state.</em> This is the reason why people often meet up in places where there's a fountain. It is not only aesthetically appealing but also<em><u> provides comfort from the hea</u></em>t.

Describe in a couple sentences how the index of refraction is related to the speed of light?
lesantik [10]

Answer: n = c / v" "c" is the speed of light in a vacuum, "v" is the speed of light in that substance and "n" is the index of refraction. According to the formula, the index of refraction is the relation between the speed of light in a vacuum and the speed of light in a substance.

Explanation: the relation is the vacuum and the speed of light in a substance.

a body of a mass 1kg suspended from a spring is found to stretch the spring by 10cm. (A) what is the spring constant? what is pe
Nikitich [7]

Answer:

(A) The spring constant is <u>98 N/m.</u>

(B) The period of oscillation is <u>0.635 s.</u>

Explanation:

Given:

Mass of the body is, m=1\ kg

Extension length of the spring is, x=10\ cm=0.1\ m

Now, let 'k' be the spring constant.

The force acting on the body is due to gravity only and is equal to its weight.

So, weight of the body is given as:

F_g=mg\\F_g=1\times 9.8\\F_g=9.8\ N

Now, we know that for a spring-mass system, the net force acting on the body is equal to the product of the spring constant and extension length. Therefore,

F_g=kx\\9.8=k(0.1)\\k=\frac{9.8}{0.1}=98\ N/m

Hence, the spring constant is 98 N/m.

(B)

Period of oscillation of a body of spring-mass system in SHM is given as:

T=2\pi\sqrt{\frac{m}{k}}

Plug in the given values and solve for period 'T'. This gives,

T=2\pi\sqrt{\frac{1}{98}}\\T=2\pi\times 0.101\\T=0.635\ s

Therefore, the period of oscillation is 0.635 s.
