Answer:

NASA sees direct proof for the hole in the ozone layer getting smaller .

Explanation:

According to an research in the year 2017 ' NASA confirmed that size of the ozone hole n September was smaller as it was in earlier three decades ago . They found that chlorine from chlorofluorocarbons (CFC) are reducing which results in the depletion of hole in the ozone layer.

Ozone layer plays an very important role in protecting life on earth from very dangerous rays which cause many deadly diseases and many other problems. Since the world banding the substances which cause ozone depletion , scientists are thinking that by the year of 2070 the hole can recover its size level that it was in year of 1980.

Two identical charges, 2 m apart, exert forces of magnitude 4 N on each other. The value of each charge is: 1. 9 × 105 C 2. 4.2

lesya692 [45]

Answer:

The value of each charge is 4.22 x 10⁻⁵ C

Explanation:

Given;

distance between the two identical charges, d = 2 m

the force of repulsion between these two charges, F = 4N

Apply Coulomb's law;

$F = \frac{kq_1q_2}{r^2} \\\\but \ q_1 =q_2,then \ let \ q_1 =q_2 = q\\\\F = \frac{kq^2}{r^2}\\\\q^2 = \frac{Fr^2}{k}\\\\q^2 = \frac{4*2^2}{9*10^9} \\\\q ^2 = 1.7778*10^{-9}\\\\q = \sqrt{1.7778*10^{-9}}\\\\q =4.22 *10^{-5} C\\\\q= q_1=q_2= 4.22 *10^{-5} C$

Therefore, the value of each charge is 4.22 x 10⁻⁵ C

1. Straight-in spaces can leave you a safer out if

Juliette [100K]

Answer:

C. you're able to reverse out of the parking spot

Explanation:

Straight-in parking is an approach of parking that allows a more flexible traffic layout where a driver can approach the spot from either direction and still safely park within the lines. It thus helps to prevent blockage of cars. Each car can move in and out freely preventing it from congestion.

This way of parking can leave you safe when you able to reverse out of the parking spot. It gives you greater control and makes it easier to maneuver out space. The benefits of Straight-in parking are,

- Allows for two-way traffic

- Drivers can line up the vehicle from multiple angles

- Saves time for drivers

In the nineteenth century, Gregor Mendel first determined some basic rules of genetics that have been observed throughout all ty

Dmitry_Shevchenko [17]

Hi!

The correct option would be A) Mendel’s genetics states laws that are now part of the theory of biological evolution.

When Darwin proposed the idea of biological evolution, which revolved around the concept that favorable genes are naturally selected into a species to ensure survival, his theory was criticized as during that time there was the idea that individual traits of two parents would present themselves as a blend in the offspring.

Gregor Mendel's theory of inheritance supported Darwin's idea as it dealt with the transmission of traits in generations through entities called genes, which were present in pairs for a particular trait.

Hope this helps!
