The main environmental effects of ozone depletion could include the following:

  • higher risk of skin cancer
  • sunburns
  • quick ageing
  • weakend immune system

<h3>What is ozone depletion?</h3>

Ozone depletion is the gradual thinning of the ozone layer in the upper atmosphere as a result of the relelase of chemical compounds or gases.

Ozone layer helps prevent the Earth surface against incoming ultraviolet radiations that could cause damage to our environment.

Therefore, the main environmental effects of ozone depletion could include the following:

  • higher risk of skin cancer
  • sunburns
  • quick ageing
  • weakend immune system

allsm [11]

Answer:

Young modulus  = 9.8 × 10⁹ N/m²

Explanation:

From the information given:

Stress = F/A

Stress = (10 × 9.8) / 0.001²

Stress = 9.8× 10⁷ N/m²

Strain = increase in length / initial length of wire

Strain = 0.02/ 2

Strain = 0.01

Now;

The Young modulus (Y)= stress/strain

Young modulus  = (9.8 × 10⁷ N/m²) /  0.01

Young modulus  = 9.8 × 10⁹ N/m²

Starting from rest, a boulder rolls down a hill with constant acceleration and travels 3.00m during the first second.
Alexus [3.1K]

Answer:

a) 9.00 m b) 6.00 m/s  c) 12.00 m/s

Explanation:

a) If the acceleration is constant, and we know that the displacement during the first second was 3.00 m, as the boulder (assumed that we can treat it as a point mass) started from rest, we can say the following:

Δx = \frac{1}{2}*a*t^{2} = 3.00 m

As t = 1 s, replacing in the expression above, and solving for a, we have:

a = \frac{2*3.00m}{1s2} = 6.00 m/s²

In order to know how far it travels during the second second, we need to know the value of the speed after the first second, as it is the initial velocity when the second second begins:

vf = v₀ + a*t ⇒ vf = 0 + 6 m/s²*1s = 6.00 m/s

The total displacement, during the second second, will be as follows:

Δx = v₀*t + \frac{1}{2}*a*t^{2} = 6.00m/s*1s +\frac{1}{2}*6.00 m/s2*1s^{2}  = 9.00 m

⇒ Δx = 9.00 m

b) At the end of the first second, the final speed can be obtained as follows:

vf = v₀ + a*t ⇒ vf = 0 + 6 m/s²*1s = 6.00 m/s

c) At the end of the second second, the final speed can be obtained as follows:

vf = v₀ + a*t ⇒ vf = 0 + 6 m/s²*2s = 12.00 m/s

You are driving 12 meters per second. What is your speed in miles per hour? (1.6km=1 mike) EXPLAIN
Blizzard [7]

1.6km = 1 mike? Wow that guy is tall.

I think you meant 1.6 km = 1 mile? Okay then if we're going 12 meters per second how much would you travel in one hour? First we need to figure out how many seconds are in an hour.  There are 60 seconds in a minute and 60 minutes in an hour so:

60×60=3600 seconds in an hour

Now we will multiply that by 12 meters per second and we get:

12\frac{m}{s} \times 3600 s=43200m

And 43200 meters is 43.2 km (1000 meters in 1 kilometer) meaning 43.2 kilometers an hour.  Since there are 1.6 km in one mile we must divide 43.2km to 1.6.

\frac{43.2}{1.6}=27mph

And so your speed is 27 miles per hour.

Why do you think medical illustrations are important to the study of human biology?
Fofino [41]

Answer:

Personally, I am sure that learning everything by looking at image is more effective than looking at a forest of letters. As for the field of science as human biology, it is very very important as well, because the illustrations are vital resource to convey important medical information that is easier to understand by showing it as a drawing rather than by only describing it with text.
