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.

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.

A block of aluminium of density 7900 kg/m3 has a volume of 250 cm. Find the
mass of the block.
Answer:
mass of block=2.7 gm
Explanation:
concept: Density=mass/volume
given:ρ=2700 kg/m^3 and v=250 cm^3 (in cm^3 not in m^3)
=> v= convert cm^3 to m^3
there fore= 1 cm^3=1 cm*1 cm*1 cm
i.e 1 cm^3=1/100*1/00*1/100 m^3 => 1 cm^3=1/1000000 m^3
ρ=m/v
=>mass=ρ*volume
=>mass=2700*1/10^-6
=>mass=2.7*10^-3 kg =>2.7 gm
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.

A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 18 A of current: through the torso of person in 2.0 ms- (a) How much charge moves during this time
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time
[tex]q=It[/tex]
Put all the values,
[tex]q=18\times 0.002\\\\q=0.036\ C[/tex]
So, 0.036 C of charge moves during this time.

A 3.00 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 124 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 11.9 m/s, while the spring is initially unstrained. What is the amplitude of the resulting simple harmonic motion
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]
Therefore the amplitude of the resulting simple harmonic motion is
[tex]A=0.185m[/tex]

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.

If all your cells were the same, could you still do everything you do now?
Explain.
Answer:
No, you couldn't function the same as you do now.
Explanation:
This is because each cell follows individual tasks, and makes up specific parts of a body. For example, if all of your cells were those of an eye, you would be missing the components of arms, legs, etc.
Answer: No
Explanation: If all the cells of our body were of the same size, shape and volume, then they would all perform the same function and the multitude of other important functions cannot be carried out, without which human life itself would not be possible.

a car travels 90 km per hour how many how many Kilometres of distance does it travel in one second
Answer:
Its Moving at a constant Speed of 90km/hr
You can convert this speed to Meters/Second or Change it to Km/Second(Because we need our distance in Km)
So 90km/hr x 1/60 x1/60
=90km/3600sec
v=0.025km/sec
When an Object Moves at Constant Speed... Its displacement(distance) is given by
d=vt
given v=0.025km/sec
t=1sec
d=0.025km/sec x 1sec
d=0.025km.
Answer:
0.025
Explanation:
speed= 90km/hr
speed in m/s= 18/5*90
= 25m/s
25 m= 25/1000km=0.025

Substitution
Deletion
Answer:
Insertion
Explanation:
Insertion mutation is a kind of mutation in which one or more nucleotide base(s) is added to the sequence, hence, changing the reading frame of the sequence. In this question, the following original and mutated sequence were given:
Original DNA Sequence: T ACACC GGCGAC GAC T
Mutated DNA Sequence: T ACAC CTTA GC GAC GAC T

What would be the force required to accelerate an object that weighs 35 N up at a rate of .60 m/s^2?
Answer: [tex]2.14\ N[/tex]
Explanation:
Given
Force required to accelerate the object at the rate of [tex]0.6\ m/s^2[/tex]
The weight of the object is [tex]W=35\ N[/tex]
Mass of the object can be identified by dividing the weight by acceleration due to gravity
[tex]\Rightarrow m=\dfrac{W}{g}\\\\\Rightarrow m=\dfrac{35}{9.8}\\\\\Rightarrow m=3.57\ kg[/tex]
[tex]\therefore \text{Force F=}m\times a\\\Rightarrow F=3.57\times 0.6\\\Rightarrow F=2.14\ N[/tex]
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
Four 29-ohm resistors are connected in series to an ideal 10-volt battery. What is the equivalent resistance of the circuit?
Answer:
Equivalent resistance of the circuit is 116 ohm.
Explanation:
Finding the equivalent resistance of the circuit. Since, 29 ohm resistors are connected in series, so
→ Equivalent resistance = R_1 + R_2 + R_3 + R_4
→ Equivalent resistance = (29 + 29 + 29 + 29) ohm
→ Equivalent resistance = 116 ohm
