Proximity -------------------- APEX

Answer: Option (b) is the correct answer.

Explanation:

Proximity means closeness, that is, whether two or more individuals are close in a relationship, time, space etc it is known as proximity between them.

Therefore, when Joanna and Janna are sitting next to each other then it means there is less space between them as they are sitting together.

Hence, we can conclude that this is an example of the importance of proximity in making friends.

A cylindrical, 0.500-m rod has a diameter of 0.02 m. The rod is stretched to a length of 0.501 m by a force of 3000 N. What is t
Salsk061 [2.6K]

Answer:

Y = 4.775 x 10⁹ Pa = 4.775 GPa

Explanation:

First, we calculate the stress on the rod:

stress = \frac{Force}{Area} = \frac{3000\ N}{\pi r^2}  \\\\stress = \frac{3000\ N}{\pi (0.01\ m)^2}\\\\stress = 9.55\ x\ 10^6\ Pa = 9.55 MPa\\

Now, we calculate the strain:

strain = \frac{Change\ in Length}{Original\ Length}\\\\strain = \frac{0.501\ m - 0.5\ m}{0.5\ m}\\\\strain =  0.002\\

Now, we will calculate the Young's Modulus (Y):

Y = \frac{stress}{strain}\\\\Y = \frac{9.55\ x\ 10^6\ Pa}{0.002} \\

<u>Y = 4.775 x 10⁹ Pa = 4.775 GPa</u>

The energy is water but i wanf to know how does it affect the enviorment?
Airida [17]
It affects the environment because more animals and plants will grow. Down side is if there are bugs or insects that need water to live, if there's more water than more bugs. If bugs also feed on plants there could be an over population.
