The lack of apparent motion of the stars is due to the vast distances involved, and not to any shortcomings in the observation techniques or instruments used such as stellar parallax.
What is Stellar Parallax?Stellar parallax is the apparent shift in the position of a nearby star relative to more distant background stars as observed from Earth, caused by the Earth's orbit around the sun. In other words, as the Earth moves in its orbit around the sun, the perspective from which we view nearby stars changes, causing those stars to appear to move slightly against the more distant background stars.
The amount of this apparent shift is directly proportional to the distance of the star from the Earth. The closer the star, the greater the parallax. By measuring the parallax of a star, astronomers can determine its distance from the Earth with a high degree of accuracy.
Stellar parallax provides one of the most direct and reliable methods for determining the distances to nearby stars and is a key tool in the study of the structure and evolution of the Milky Way galaxy and the universe as a whole.
The most likely reason for the apparent lack of motion of the stars is due to the great distances between Earth and the stars. Stellar parallax is the apparent shift in the position of a star as observed from two different points in Earth's orbit, such as from opposite sides of the Earth's orbit around the sun. This apparent shift is caused by the change in the observer's perspective as the Earth moves.

A bus can travel 63 miles in 1. 4 hours. If its speed is increased by 10 mph, how far can the bus travel in 4 hours?.
The distance traveled by bus after its speed increased by 10 mph is 220 miles.
Given that, the bus can travel 63 miles in 1.4 hours.
The speed of the bus is:
speed = 63/1.4 mph
speed = 45 mph

What is accelaration?Acceleration is the rate if we can object increase is speed velocity of rate of change it is the rate of change of velocity of a time at the rate of change of the position of an object acceleration can be either positive when the speed of an object increasing a negative in the speed of the object is decreasing.
Acceleration is the rate of change in velocity over time and can be calculated using the equation a=v/t, where a is acceleration, v is the change in velocity (in this case, 40 m/s) and t is the time taken (8 seconds). Therefore, razorback's acceleration is 5 m/s^2. This means razorback's velocity was increasing by 5 m/s every second.
To put this into perspective, it means razorback was running at 10 m/s after 4 seconds and at 15 m/s after 6 seconds. This makes sense as he was able to reach the rabbit in 8 seconds.

c. 39.4%
d. 78.8%
e. 68.27%
The percentage of people with blood pressure between 120 mm and 160 mm is approximately(d) 78.8%.
To estimate the percentage of people with blood pressure below 120 mm, we need to calculate the z-score for that value:
z = (120 - 140) / 20 = -1
Using a standard normal table, we can find the proportion of the distribution below a z-score of -1, which is approximately 0.1587. However, since we want the percentage below 120 mm, we need to multiply this proportion by 100 and round to one decimal place:
0.1587 x 100 ≈ 15.9%
Therefore, the percentage of people with blood pressure below 120 mm is approximately 15.9%.
To estimate the percentage of people with blood pressure between 120 mm and 160 mm, we need to calculate the z-scores for both values:
z1 = (120 - 140) / 20 = -1
z2 = (160 - 140) / 20 = 1
Using a standard normal table, we can find the proportion of the distribution between these two z-scores, which is approximately 0.7887. To find the percentage between 120 mm and 160 mm, we need to multiply this proportion by 100 and round to one decimal place:
0.7887 x 100 ≈ 78.8%

A car starts from rest on a curve with a radius of 150 m and tangential acceleration of 1.3 m/s2 .Through what angle will the car have traveled when the magnitude of its total acceleration is 3.0 m/s2 ?
We can start by using the formula for tangential acceleration:
a_t = r * α
How to use tangential acceleration ?where a_t is the tangential acceleration, r is the radius of the curve, and α is the angular acceleration. Rearranging this equation, we get:α = a_t / r = 1.3 m/s^2 / 150 m = 0.00867 rad/s^2
Next, we can use the formula for the magnitude of total acceleration:a_total = √(a_t^2 + a_c^2)
where a_c is the centripetal acceleration. We can rearrange this equation to solve for a_c:
a_c = √(a_total^2 - a_t^2) = √(3.0^2 - 1.3^2) = 2.5 m/s^2
Now, we can use the formula for centripetal acceleration:a_c = r * ω^2
where ω is the angular velocity. Rearranging this equation, we get:
ω = √(a_c / r) = √(2.5 m/s^2 / 150 m) = 0.1155 rad/s
Finally, we can use the formula for angular displacement:
θ= ω^2 * t / 2
where t is the time elapsed. Since the car starts from rest, we can use the formula for initial velocity and acceleration:v_i = 0
a = a_t
to find the time it takes for the car to reach the required total acceleration of 3.0 m/s^2:
a = (v_f - v_i) / t
t = (v_f - v_i) / a
t = v_f / a
where v_f is the final velocity. Using the formula for final velocity and the fact that the car starts from rest, we get:
v_f^2 = 2 * a_t * θ
v_f = √(2 * a_t * θ)
t = √(2 * θ / a_t)
Substituting the values we have calculated, we get:t = √(2 * θ / 1.3) = √(1.5385 * θ)
t = v_f / a = √(2 * a_t * θ) / a_t = √(2 * θ / 1.3)
Setting these two expressions for t equal to each other, we get:
√(1.5385 * θ) = √(2 * θ / 1.3)
Squaring both sides and solving for θ, we get:
θ = 4.89 radians
Therefore, the car will have traveled through an angle of 4.89 radians when the magnitude of its total acceleration is 3.0 m/s^2.

why do we want the water to stabilize at the boiling point before removing the metal object? explain
The metal item is heated evenly and fully by allowing the water to stabilise, guaranteeing that any heating effects are realised.
Depending on the metal's thermal conductivity and specific heat capacity, when a metal item is submerged in boiling water, it warms up and may even reach a temperature greater than the boiling point of water.
The metal object's high temperature can cause the water around its surface to evaporate quickly when it is abruptly withdrawn from the boiling water. This can result in bubbles that can burst forcefully and cause splattering.
Burns or other damage may arise from this.
The metal and the water are at the same temperature and there is no longer a temperature gradient between them when the water is allowed to reach its boiling point before the metal item is removed.
As a result, there will be less severe water vaporisation, which lowers the possibility of splattering and harm.
Additionally, letting the water to stabilise guarantees that any intended effects of the heating are realised and that the metal item is heated evenly and fully.

When a boxer is moving away from a punch, the force experienced is reduced because .
When a boxer is moving away from a punch, the force experienced is reduced because the time of impact is increased.
What is force?The force of a punch is a product of mass and acceleration. The mass of the boxer and the fist of the opponent are constant, so the acceleration of the punch is also constant. However, if the boxer moves away from the punch, the distance that the fist has to travel to make contact with the boxer's body increases. As a result, the time of impact is longer, and the force is spread out over a longer period. This means that the force of the punch is reduced and is less likely to cause injury or knock the boxer down.
In addition, moving away from a punch can also reduce the accuracy of the punch, as the opponent's punch may miss its intended target due to the change in distance between the two boxers.
