Describe succinctly the relationship between how far a galaxy is from us (its distance), versus how fast it is moving.
Answer:
Distance is directly proportional to the velocity
Explanation:
In 1929, Edwin Hubble's wrote an article that talked about relationship between the distance and recession speed/velocity of galaxies which led to what is known as the Hubble Law. This law states that galaxies are moving away from the earth at velocities proportional to their distances.
Thus is written as;
v = H_o•d
Where;
v is velocity
d is distance
H_o is Hubble's constant rate of cosmic expansion.
He came to this conclusion by generating a graph known as Hubble's classic graph which was a graph of observed velocity vs distance for nearby galaxies.

What do you think is the factor that causes projectile path to bend?
The movement of an object in a curved path toward the ground due to the application of a horizontal force and the downward force of gravity is projectile motion. The gravity is the factor that leads to bend of projectile path.
What is gravity?Gravity is the universal force of attraction that holds all matter together. It is by far the weakest known natural force and thus has no influence on the internal properties of everyday matter.
A projectile is an object whose main force is gravity. Because gravity is a downward force, it causes a projectile to accelerate downward.
Thus, the factor that causes projectile path to bend is gravity.

A man was standing on top of an office building and ‘accidentally' dropped an rock off the roof How tall is the building if the total velocity is 123m/s and the horizontal velocity is 22m/s?
Answer:
The building is 746.666 meters high.
Explanation:
We know the total velocity of the rock ([tex]v[/tex]), in meters per second, and its horizontal speed ([tex]v_{x}[/tex]), in meters per second, at the moment right before its impact. It should be noted that the rock is experimenting a parabolic motion, which is the combination of a horizontal motion at constant speed and a free fall, which is an uniform accelerated motion due to gravity.
The final vertical speed of the rock ([tex]v_{y}[/tex]), in meters per second, is determined by the following Pythagoric formula:
[tex]v_{y} = \sqrt{v^{2}-v_{x}^{2}}[/tex] (1)
If we know that [tex]v = 123\,\frac{m}{s}[/tex] and [tex]v_{x} = 22\,\frac{m}{s}[/tex], then the final vertical speed is:
[tex]v_{y} = \sqrt{\left(123\,\frac{m}{s} \right)^{2}-\left(22\,\frac{m}{s} \right)^{2}}[/tex]
[tex]v_{y} \approx 121.017\,\frac{m}{s}[/tex]
Now we determine the height of the building ([tex]h[/tex]), in meters, by the use of the following kinematic expression:
[tex]h = \frac{v_{y}^{2}-v_{y,o}^{2}}{2\cdot g}[/tex] (2)
Where:
[tex]v_{y,o}[/tex] - Initial vertical speed of the rock, in meters per second.
[tex]g[/tex] - Gravitational acceleration, in meters per square second.
If we know that [tex]v_{y,o} = 0\,\frac{m}{s}[/tex], [tex]v_{y} \approx 121.017\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the height of the building is:
[tex]h = \frac{v_{y}^{2}-v_{y,o}^{2}}{2\cdot g}[/tex]
[tex]h = \frac{\left(121.017\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]
[tex]h = 746.666\,m[/tex]
The building is 746.666 meters high.

easy hope it helps#CARRYONLEARNING!A cell of emf 18v has an internal resistance of 3ohm . the terminal p.d of the battery becomes 15v when connected by a wire. find the resistance of the wire.
Answer:
Resistance = 15 Ohms
Explanation:
Given the following data;
Emf voltage = 18 V
Internal resistance = 3 Ohms
Potential difference = 15V
To find the resistance of the wire;
First of all, we would determine the current flowing through the wire.
Mathematically, the terminal potential difference is given by the formula;
V = E - IR
Where;
V is the terminal potential difference.
E is the electromotive force (emf).
I is the current.
R is the internal resistance.
15 = 18 - I*3
15 = 18 - 3I
3I = 18 - 15
3I = 3
I = 1 Amperes
Next, we find the resistance of the wire;
Voltage = current * resistance
Substituting into the formula, we have;
15 = 1 * resistance
Resistance = 15/1
Resistance = 15 Ohms

Determine the acceleration of gravity.
Answer:
1. Distance, S = 26.58 meters
2. Acceleration of gravity, g = 58.60 m/s²
Explanation:
1. Given the following data;
Initial velocity = 4.66 m/s
Acceleration = 5.66 m/s²
Time = 2.35 seconds
To find the distance travelled by the object, we would use the second equation of motion;
S = ut + ½at²
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
S = 4.66*2.35 + ½*5.66*2.35²
S = 10.951 + (2.83 * 5.5225)
S = 10.951 + 15.629
S = 26.58 meters
2. Given the following data;
Displacement (height) = 1.55 m
Time, t = 0.23 seconds
To find the acceleration of gravity, we would use the following formula;
Height = ½gt²
Substituting into the formula, we have;
1.55 = ½ * g * 0.23²
1.55 = ½ * g * 0.0529
1.55 = 0.02645g
Acceleration of gravity, g = 1.55/0.02645
Acceleration of gravity, g = 58.60 m/s²

Randy works out every day because he wants to make the football team. Randy's
purpose for working out is described as an example of
A
motivation
B
organization
C
overload
D
sportmanship
The purpose of working out is described as an example of motivation, as Randy works out every day because he wants to make the football team, so option A is correct.
What is the Motivation?In humans and other animals, motivation is what causes an activity to start, continue, or end at a specific time. The interpretation of motivational states as internal forces that increase an agent's propensity to engage in goal-directed behavior is common. Conflicting theories exist on the makeup of motivated moods. They are known as content theories, and they aim to explain the typical or consistent motives.
Behaviorist theories seek to elucidate behavior solely in terms of the relationship between the circumstance and outward, apparent conduct, avoiding any explicit mention of conscious mental states.
Therefore, the purpose of Randy's working out daily is described as an example of motivation, he is motivated to make a football team.

Answer:
[tex]A=0.185m[/tex]
Explanation:
From the question we are told that
Mass of Block [tex]M=3*10^-2kg[/tex]
Spring constant [tex]\mu=124 N/m[/tex]
Initial Speed [tex]V_1=11.9m/s[/tex]
Generally the equation for Kinetic Energy is mathematically given by
[tex]K.E=1/2 mv^2[/tex]
Therefore
[tex]K.E_1=1/2*0.03*11.9^2[/tex]
[tex]K.E_1=2.12J[/tex]
Where
[tex]Initial K.E_1=Final K.E[/tex]
Generally the equation for Final Energy stored is mathematically given by
[tex]K.E_2=0.5\mu a^2[/tex]
Therefore
[tex]K.E_1=K.E_2[/tex]
[tex]0.5\mu A^2=2.12J[/tex]
[tex]A=\sqrt{\frac{2.12}{0.5*124}}[/tex]
[tex]A=0.185m[/tex]

Can you tell from an FBD if an object is moving or not? Explain your response.
Answer:
Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion
Explanation:
A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object
When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or continue its uniform motion on a straight path unless a force acts on the object
The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest
Therefore;
From a FBD it is possible to tell if an object is moving or not.
