To solve this, we must be knowing each and everything related to atmosphere. Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.
What is atmosphere?
The atmosphere is more than simply the beautiful sky above. The atmosphere is made up of numerous levels of gases that surround the planet.
The word "atmo," which meaning vapor, smoke, or fog in Greek, is the source of the atmosphere's name. "Sphere" comes from the Greek word sphaira, which meaning ball. The term "atmosphere" refers to a vapor ball. Thermosphere is the layer of the atmosphere has no definite outer limit. The thermosphere is located between 53 miles (85 kilometers) and 375 mile (600 kilometers).
Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.

The exosphere is the layer of the atmosphere that has no clear outer limit. The exosphere is the Earth's atmosphere's outermost layer, extending from the top of the thermosphere to the edge of space.
The exosphere, unlike the other layers of the atmosphere, gradually transitions into the vacuum of outer space with no clearly defined border.
The density and spread out of gas molecules in the exosphere are exceedingly low.
This area is made up mostly of relatively light gases like hydrogen and helium, and it is where satellites and other spacecraft circle the Earth.
Thus, the progressive reduction in density as the atmosphere merges into space accounts for the lack of a well-defined outer boundary.

Answer:
P1 = momentum before collision = .5 kg * .32 m/s = .16 kg-m/s
Momentum is conserved
P1 = P2 = V * (M + m) = .16 kg-m/sec
V = .16 kg-m/sec / (.5 kg + .3 kg) = .2 m/sec

Why are some fibers spun together to form yarns?
Answer:
Spun yarns are produced by placing a series of individual fibres or filaments together to form a continuous assembly of overlapping fibres, usually bound together by twist. This operation is required in wool spinning because different parts of the fleece contain fibres of different length and thickness.
Which does not take the direction of the motion into account?
Displacement
Distance
velocity
Velocity and displacement take direction of motion into account while distance does not take direction of motion into account.
Vector quantities take into account both magnitude and direction of motion while scalar quantities only take the magnitude of motion into account. In describing the motion of an object, we use terms such as; velocity, distance, displacement etc.
Looking at the options provided in the question, displacement and velocity are vectors hence they take the direction of motion into account. Distance is a scalar quantity hence it does not take direction of motion into account.

A 0.80-kg ball is thrown with a velocity of 13 m/s. The ball hit a 0.12-kg bowling pin. When the ball hits the pin, the pin goes flying forward at 6 m/s. What is the velocity of the ball after it hits the pin?
When the ball of mass 0.80kg hits a bowling pin of 0.12 kg, the velocity of the ball after it hits the pin = 12.1 m/s
The mass of the ball, [tex]m_1=0.80 kg[/tex]

an empty boat floats in water with 10% of its volume submerged. and when it is loaded with 1200kg , the volume submerged will increase to 70% of the total volume . calculate the mass of the empty boat
Let volume of empty boat be = 100% = 1V
and mass of boat be M
In water 10%, 0.1V of the volume is submerged.
Mass, m of 1200kg increases the submerging from 10%, 0.1V to 70%, 0.7V
M leads to 0.1V boat submerging
boat submerging.
M + 1200kg leads to 0.7V boat submerging.
This is 60%, 0.6 V increase
By comparison
(M+1200kg) * 0.1V = 0.7V * M
0.1M + 120kg = 0.7M
120kg = 0.7M - 0.1M
120kg = 0.6M
M = (120/0.6)kg
M = 200kg.
The mass of the boat is 200kg.

Can someone help me with these 3 questions!!!
Answer:
Below
Explanation:
To find the height of a ball thrown upwards we can use this formula :
vf^2 = vi^2 + 2ad
0^2 = 22^2 + 2(-9.8)d
484 = 19.6d
24.69 = d
25 m = d
To find the time of the phone dropped we can use this formula :
t = √2d/g
t = √2(15) / 9.8
t = √30/9.8
t =√3.142857
t = 1.749
t = 1.7 seconds
For a) since this object is free falling we know that it will accelerate towards earth at a rate of 9.8 m/s^2. The slope of a velocity time graph gives us the acceleration of the object. So in this case the slope would be 9.8 m.s^2

what is occurring when a light wave goes through a pane of glass in a window?
Answer:
transmission: the passing of a wave through an object
Explanation:
Two motorcycles travel along a straight road heading due north. At t = 0 motorcycle 1 is at x = 50 m and moves with a constant speed of 6.50 m/s; motorcycle 2 starts from rest at x = 0 and moves with constant acceleration. Motorcycle 2 passes motorcycle 1 at the time t = 10.08.
Part B What is the position of the two motorcycles when motorcycle 2 passes motorcycle 1? Express your answer to three significant figures and include the appropriate units.
Part C What is the acceleration of motorcycle 2? Express your answer to three significant figures and include the appropriate units.
Answer:
Vf = 23 m/s
Explanation:
First we need to find the distance covered by the motorcycle 2 when it passes motorcycle 1. Using the uniform speed equation for motorcycle 1:
s₁ = v₁t₁
where,
s₁ = distance covered by motorcycle 1 = ?
v₁ = speed of motorcycle 1 = 6.5 m/s
t₁ = time = 10 s
Therefore,
s₁ = (6.5 m/s)(10 s)
s₁ = 65 m
Now, for the distance covered by motorcycle 2 at the meeting point. Since, the motorcycle started 50 m ahead of motorcycle 2. Therefore,
s₂ = s₁ + 50 m
s₂ = 65 m + 50 m
s₂ = 115 m
Now, using second equation of motion for motorcycle 2:
s₂ = Vi t + (1/2)at²
where,
Vi = initial velocity of motorcycle 2 = 0 m/s
Therefore,
115 m = (0 m/s)(10 s) + (1/2)(a)(10 s)²
a = 230 m/100 s²
a = 2.3 m/s²
Now, using 1st equation of motion:
Vf = Vi + at
Vf = 0 m/s + (2.3 m/s²)(10 s)
Vf = 23 m/s

What do you think will happen to current if we increase or decrease the resistance of the connecting wire?
Answer:
If resistance is increased, the current decreases and if the resistance is decreased, the current flowing through the wire increases.
Explanation:
V = IR is ohm's law which implies I = V/R, where I is the current and V is the voltage and R is the resistance. Hence, I is inversely proportional to R.

what is the energy of light for a single photon that has a wavelength of 347 nm?
The energy of light for a single photon that has a wavelength of 347 nm is 5.698 × 10-¹⁹ J
HOW TO CALCULATE ENERGY:
The energy of a photon of light can be calculated by using the following formula:E = hf
Where;
E = energy of photon (J)h = Planck's constant (6.626 × 10-³⁴J/s)f = frequency (Hz)However, the frequency must first be calculated using the formula as follows:λ = v/f
Where;
