The solar system is very large with the boundaries located around the Orth cloud 100,000 Astronomical Units away
The correct option for, the distance to the nearest star if the solar system were the size of a campus is the option;
About a mile away
The reason the above selection is correct is as follows:
The nearest star to the solar system is Proxima CentauriThe distance of the nearest star to the solar system from Earth is 40,208,000,000,000 kilometers awayThe area of the solar system is about (π × (10⁵ × 149.6 × 10⁶)²) km²The size of one of the largest campus can be taken as 27,000 acres = 109.2651 km²The ratio of the area of the solar system to the area of a campus = (π × (10⁵ × 149.6 × 10⁶)²)/(109.2651) = 6.4347487 × 10²⁴
Therefore, the linear scale factor ≈ √(6.4347487 × 10²⁴) ≈ 2.5366807 × 10¹²
Therefore, the corresponding distance to the distance of the nearest star to the solar system, X is given as follows;
X = (40,208,000,000,000 km)/(2.5366807 × 10¹²) ≈ 15.85 km ≈ 9.85 miles
Given that compared with the largest campus the distance is at most approximately 9.85 mile, if the solar system is taken to be a much smaller campus, the distance of the closest star Proxima Centauri will be about a mile away

3. The equation of motion of a SHM oscillator is x=0.5msin(2πf)t, where x is in meter and t is in seconds. If the position of the oscillator is at x=0.25m and t=0.25s . what is the frequency of the oscillator ?
Answer:
f = 1/3 Hz
Explanation:
0.25 = 0.5 sin(2πf)0.25
0.5 = sin(0.5πf)
take arcsine of both sides in radians
0.52359 = 0.5πf
f = 0.52359 / 0.5π = 0.33333...
The frequency of the oscillator is 0.33 Hz.
We have an equation of SHM.
We have to identify the frequency of the oscillator.
What are the conditions for a motion to be Simple Harmonic ?The conditions are -
The restoring force must be proportional to the displacement.The restoring force should act opposite to the direction of motion with no drag forces or friction.According to the question, we have -
x = 0.5 sin(2πft)
Substituting the values -
0.25 = 0.5 sin(2πft)
sin(2πft) = 0.5
sin(2πft) = 1/2
sin(2πft) = sin(π/6)
2πft = π/6
2ft = 1/6
f = [tex]\frac{1}{12t}[/tex] = [tex]\frac{1}{12\times 0.25}[/tex] = 0.33 Hz
f = 0.33 Hz
Hence, the frequency of the oscillator is 0.33 Hz

Relate states of matter with heat by a proper graph and describe the graph fully by your
own words.
An increase in temperature leads to an increase in absorbed heat which in turn leads to a change in state of the substance/matter.
From the graph attached below the increase in temperature causes the change in state of the matter ( i.e. water from solid to a gaseous state ), while the plateau represents the transition phase it also indicates the exact temperature wherein the substance changes from one state to another. as the temperature increases the substance absorbs more heat which leads to its change in state.
Attached below is a graphical representation describing the change in state of a substance ( water )
From the graph we can conclude that an increase in temperature leads to an increase in absorbed heat which in turn leads to a change in state of the substance.

What is the initial velocity for a zombie that accelerates uniformly at 6.1 m/s2 for 7.0
seconds along a 15 m path?
Answer:
Therefore, the initial velocity of zombie is 19.2 m/s.
Explanation:
Given:
The acceleration of motion of zombie is [tex]a=6.1 \rm{m/s^{2}}[/tex]
Zombie accelerates for [tex]t=7\rm{s}[/tex]
The distance covered by the zombie is [tex]s=15\rm{m}[/tex]
To find the initial velocity [tex]u[/tex] of the motion, use the second equation of motion,

For each indicated point on the trajectory, place the vectors that qualitatively represent the relative velocity and acceleration of a ball that is thrown straight up, from the time it is thrown to the time it is caught. Note that the horizontal displacement of the ball is only for visual clarity. The vector for the acceleration due to gravity is at the bottom right of the figure for reference.
The direction of the velocity of an object is always in the direction of the object's motion while the acceleration due to gravity is always directed downwards.
The direction of velocity of an object projected upwards points upwards from the starting position until the object reaches maximum height, from the maximum height the velocity points downwards and this velocity increases until the object hits the ground.
The object attains maximum velocity before hitting the ground.At the maximum height the final velocity of the object is zeroThe acceleration due to gravity doesn't always point in the direction of the object's motion, in fact the direction of the acceleration due to gravity is always downwards.
In the given charts we are going to represent the direction of the velocity and acceleration as follows;

a) positive, positive.
b) negative, positive.
c) negative, negative.
d) positive, negative.
(A)
Explanation:
If the displacement is given by

a. His average speed can be greater than the magnitude of his average velocity.
b. His average speed can be less than the magnitude of his average velocity.
c. Since he is walking along a straight path, his average acceleration must be zero.
d. His average velocity must be zero.
Answer:
a. His average speed can be greater than the magnitude of his average velocity.
Explanation:
As speed is distance traveled over time traveled, this is always greater than zero if he has moved at all.
velocity is displacement over time traveled. As the man is allowed to return to the point of origin, his velocity at some point might be zero while his speed is positive.

Answer:
Base units are defined units based on specific objects or events in the physical world. Derived units are defined by combining base units.
Base units are defined by a particular process of measuring a base quantity whereas derived units are defined as algebraic combinations of base units. For example, length is a base quantity in both SI and the English system, but the meter is a base unit in the SI system only.
