Explanation:
In the stratosphere the ozone layer absorbs and scatters the solar ultraviolet radiation. In the mesosphere meteors burn up. In the thermosphere aurora and satellites occur. In the ionosphere overlapping into the mesosphere and thermosphere occur.
Answer:
Thermospheric temperatures increase with altitude due to the absorption of highly energetic solar radiation. Radiation causes the atmosphere particles in this layer to become electrically charged, enabling radio waves to be refracted and thus be received beyond the horizon. This is how solar radiation can affect the thermosphere.

A bear is sitting at rest on a tricycle. The bear then starts to accelerate uniformly at a rate of 2.5
m/s2. How long will it take the bear to reach a velocity of 15 m/s?
Answers
Answer:
15 m/s
Explanation:
Initial velocity, u = 0
Acceleration of bear, a = 2.5 m/s²
We need to find time taken by bear to reach a velocity of 15 m/s.
Acceleration is equal to the rate of change of velocity. So,
[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{15-0}{2.5}\\\\t=6\ s[/tex]
It will take 6 seconds to reach a velocity of 15 m/s.

Explanation:
Suppose Mitch Marner (mass=80kg) and Zdano Chara (mass=116kg) collide head-on at the blue line when Marner is skating 10m/s and Chara is standing still. Whose velocity would change more and Why?
Answers
Answer:
1) The person whose velocity changes more is Marner
2) The change in velocity of Marner is more than the change in velocity of Chara because Chara has more mass than Marner
Explanation:
The given information are
The mass of Mitch Marner = 80 kg
The mass of Zdano Chara = 116 kg
Marner's skating speed before the collision = 10 m/s
From the principle of conservation of linear momentum, we have;
Total initial momentum before the collision = Total final momentum after the collision
m₁×u₁ + m₂×u₂ = m₁×v₁ + m₂×v₂
Where;
m₁ = The mass of Mitch Marner = 80 kg
m₂ = The mass of Zdano Chara = 116 kg
u₁ = The initial velocity of Mitch Marner = 10 m/s
u₂ = The initial velocity of Zdano Chara = 0 m/s
v₁ = The final velocity of Mitch Marner
v₂ = The final velocity of Zdano Chara
Given that the collision is head on, they can be assumed to have an equal instantaneous velocity immediately after collision, therefore;
v₁ = v₂ = v
We have;
m₁×u₁ + m₂×u₂ = (m₁ + m₂) × v₂
By substituting the values, we have;
80 × 10 + 110 × 0 = (80 + 110) × v = 190 × v
Which gives;
80 × 10 + 110 × 0 = 190 × v
800 = 190 × v
v = 800/190 = 80/19 = [tex]4\frac{4}{19} \ m/s[/tex]
Therefore the instantaneous final velocity of both Marner and Chara is [tex]4\frac{4}{19} \ m/s[/tex]
The change in velocity of Marner = [tex]10 - 4\frac{4}{19} = 5\frac{15}{19} \ m/s[/tex]
The change in velocity of Chara = [tex]4\frac{4}{19} - 0 = 4\frac{4}{19} \ m/s[/tex]
Therefore;
1) The person whose velocity changes more is Marner
2) The reason is because the ratio of her mass to the combined mass of both of them is less than the ratio of the Chara;s mass to the combined mass of them both
Which means that the change in velocity of Marner is more than the change in velocity of Chara because Chara has more mass than Marner.

If mass A is 1.0 kg, mass B is 5.0 kg, and the frictional pulley has a mass of 0.5 kg and a radius of 0.15 m, what is the velocity of A and B at 0.5 seconds?
a. A = 1.72 m/s, B = 0.22 m/s
c. A = 0.22 m/s, B = 1.72 m/s
b. A = 3.14 m/s, B = -3.14 m/s
d. A = -3.14 m/s, B = 3.14 m/s
Answers
Answer:
b. A = 3.14 m/s, B = -3.14 m/s
Explanation:
Assuming this refers to an Atwood machine, draw free body diagrams for each mass.
For mass A, there are two forces: tension T₁ pulling up and weight m₁g pulling down.
For mass B, there are two forces: tension T₂ pulling up and weight m₂g pulling down.
For the pulley, there are two torques: tension T₁r pulling counterclockwise and tension T₂r pulling clockwise.
Sum of forces on A in the +y direction:
∑F = ma
T₁ − m₁g = m₁a
T₁ = m₁g + m₁a
Sum of forces on B in the -y direction:
∑F = ma
m₂g − T₂ = m₂a
T₂ = m₂g − m₂a
Sum of torques on the pulley in the clockwise direction:
∑τ = Iα
T₂r − T₁r = (½ mr²) (a/r)
T₂ − T₁ = ½ ma
Substitute:
m₂g − m₂a − (m₁g + m₁a) = ½ ma
m₂g − m₂a − m₁g − m₁a = ½ ma
m₂g − m₁g = m₂a + m₁a + ½ ma
g (m₂ − m₁) = a (m₂ + m₁ + ½ m)
a = g (m₂ − m₁) / (m₂ + m₁ + ½ m)
a = (9.8 m/s²) (5.0 kg − 1.0 kg) / (5.0 kg + 1.0 kg + ½ (0.5 kg))
a = 6.272 m/s²
Given:
v₀ = 0 m/s
a = 6.272 m/s²
t = 0.5 s
Find: v
v = at + v₀
v = (6.272 m/s²) (0.5 s) + 0 m/s
v = 3.14 m/s
Therefore, mass A will rise at 3.14 m/s, and mass B will fall at 3.14 m/s.
What are aerial plants
Answers
Answer:
Aerial plants are plants that lives in air or wind the wind serves as the water of the plants. Most aerial plants are found in tropical and equatorial regions of the world. In evergreen rain forests, the foliage is so thick that some plants have evolved aerial roots to allow them to absorb more sunlight. The development of aerial roots is
thus an evolutionary process.Aerial roots are often thick and spread around the parent tree. The Banyan tree can have several aerial roots as it gets older.

Answers
Answer:
First law: An object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force. (i.e. Objects in motion tend to stay in motion. Objects at rest tend to stay at rest.)
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

An aeroplane moving horizontally with a speed of 200 m/s drops a food packet while flying at a height of 396.9 m. The time taken by the food packet to reach the ground and its horizontal range is ...
A.5 s and 1000 m
B.9 s and 1800 m
C.8 s and 1600 m
Answers
So let’s find time using the kinematic equations:
Yf = Yi + Viyt + 1/2at^2
-396.9 = 0t - 4.9t^2
I multiplied gravity by 1/2 and brought the initial height to the left side
So now we have -4.9t^2 = -396.9
Divide both sides by -4.9 and take the square root of the answer to find time. I got 9 seconds
Now plug this information into the horizontal displacement equation for projectile motion:
Xf = Xi +Vixt
Xf = 200(9)
Xf = 1800 meters
A 100-m long ski lift carries skiers from a station at the foot of a slope to a second
station 40 m above. What is the IMA of the lift?
40
Answers
Answer:
12
Explanation:
Explanation:
The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (Fw), and the input force Fi applied to move the object along the slope:
ima= {Fw}÷{Fi},
The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope ll , i.e.
Fw h = Fi L
From this we find
{Fw}÷{Fi} = {L}÷{h}
Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:
ima= {L}÷{h} = {100m}÷{40m}=2.5
