Why are solar winds potentially fatal for organisms living on earth?

Physics
1 answer:
Amiraneli [1.4K]3 years ago
7 0
Solar winds contain high levels of radiation which could lead to various health related complications in living organisms on Earth. These complications include and are not limited to radiation sickness, chromosomal damage, and cancer. However, solar winds are blocked by the Earth's magnetic field, only posing problems to our telecommunications.

How does deforestation contribute to the greenhouse effect?
bija089 [108]
There are two main effects of deforestation on global warming: 1) the "slash and burn" technique used to clear the forest releases carbon dioxide into the atmosphere, and 2) destruction of living trees reduces the amount of photosynthesis, a process that removes carbon dioxide from the atmosphere and stores it in the plants as carbon. Carbon dioxide is one of the major gases contributing to global warming, and increasing its concentration will affect the amount of warming that occurs.

A camera lens focuses on an object 75.0 cm from the lensThe image forms 3.50 cm behind the lens. What is the magnification of th
N76 [4]

Answer:

7/150

Explanation:

The following data were obtained from the question:

Object distance (u) = 75cm

Image distance (v) = 3.5cm

Magnification (M) =..?

Magnification is simply defined as:

Magnification (M) = Image distance (v)/ object distance (u)

M = v /u

With the above formula, we can obtain the magnification of the image as follow:

M = v/u

M = 3.5/75

M = 7/150

Therefore, the magnification of the image is 7/150.

You kick a ball with a speed of 14 m/s at an angle of 51°. How far away does the ball land?
In-s [12.5K]
-- The vertical component of the ball's velocity is 14 sin(<span>51°) = 10.88 m/s

-- The acceleration of gravity is 9.8 m/s².

-- The ball rises for 10.88/9.8 seconds, then stops rising, and drops for the
same amount of time before it hits the ground.

-- Altogether, the ball is in the air for (2 x 10.88)/(9.8) = 2.22 seconds
==================================

-- The horizontal component of the ball's velocity is  14 cos(</span><span>51°) = 8.81 m/s

-- At this speed, it covers a horizontal distance of (8.81) x (2.22) = <em><u>19.56 meters</u></em>
before it hits the ground.


As usual when we're discussing this stuff, we completely ignore air resistance.

Find the velocity and distance travelled of a car that is accelerating at 3 m/s2 for 4 seconds.
marta [7]

Explanation:

Given:

v₀ = 0 m/s

a = 3 m/s²

t = 4 s

Find: Δx and v

Δx = v₀ t + ½ at²

Δx = (0 m/s) (4 s) + ½ (3 m/s²) (4 s)²

Δx = 24 m

v = at + v₀

v = (3 m/s²) (4 s) + 0 m/s

v = 12 m/s
