Answer:
No
Explanation:
Given the relative scale (1mm = 1mile) lets calculate the size of the Sun and distance of planets from the Sun in mm.
Diameter of Sun = 864938 miles = 864938 mm = 864.938 meters
Distance of Earth from the Sun = 92955810 miles = 92955810 mm = 92.955 km = 57.75 miles
Distance of Jupiter from Sun = 480000000 miles = 480000000 mm = 480 km = 298 miles
As can be seen, the magnitude of scaled down distances is too huge to fit inside a city.
It will not be practically possible to make such a model.

What is the wavelength of an infrared wave with a frequency of 4.2 x1014 Hz?
The wavelength of an infrared wave with a given frequency is 7.14 x 10⁻⁵ m.
What is frequency?Frequency is the number of cycles per second moved by the wave.
The frequency and wavelength is related as
λ = c/f
where c = velocity of sound wave in vacuum = 3×10⁸ m/s
Given is the frequency of the infrared wave f = 4.2×10^14, then wavelength will be
λ = 3 x10⁸ / 4.2 x 1

Bob is pulling a 30 kg filing cabinet with a force of 200 n, but the filing cabinet refuses to move. the coefficient of static friction between the filing cabinet and the floor is 0.80. what is the magnitude of the friction force on the filing cabinet?
Final answer:
The magnitude of the friction force opposing the filing cabinet is 200 N, equal to the applied force, since it does not exceed the maximum static frictional force of 235.2 N calculated using the coefficient of static friction and the normal force.
Explanation:
The magnitude of the friction force on the filing cabinet can be determined by using the coefficient of static friction and the normal force acting on the cabinet. Since the cabinet is not moving, the static frictional force will be equal to the force applied until it reaches its maximum value, which can be calculated as μs N, where μs is the coefficient of static friction and N is the normal force. The normal force is equal to the weight of the cabinet (mass times the acceleration due to gravity, g). For a 30 kg filing cabinet, the normal force N is equal to 30 kg × 9.8 m/s², which equals 294 N. Hence, the maximum static frictional force is 0.80 × 294 N = 235.2 N. Since the cabinet does not move when a 200 N force is applied, the frictional force opposing it is also 200 N, which is less than the maximum static friction of 235.2 N.
Final answer:
The friction force on the filing cabinet is 200 N, which is the same as the applied force and within the maximum static friction value given by the coefficient of static friction multiplied by the normal force.
Explanation:
The magnitude of the friction force on the filing cabinet can be found by using the coefficient of static friction and the normal force. The normal force is equal to the weight of the cabinet, which is the mass (30 kg) multiplied by the acceleration due to gravity (9.8 m/s²). This gives a normal force of (30 kg)(9.8 m/s²) = 294 N. The maximum static friction force can be calculated with the formula fs(max) = μs N, where μs is the coefficient of static friction and N is the normal force. Since the cabinet doesn't move, the static friction force must equal the applied force up to its maximum value, which is determined by the coefficient of static friction (0.80).
Therefore, the maximum static friction force that can act on the filing cabinet is fs(max) = (0.80)(294 N) = 235.2 N. Since 200 N is being applied to move the cabinet, and it does not move, the friction force acting on the cabinet is 200 N, which is the same as the applied force and less than the maximum static friction force.

A car drives horizontally off the edge of a cliff that is 40.8 m high. the police at the scene of the accident note that the point of impact is 121 m from the base of the cliff. how fast was the car traveling when it drove off the cliff?
Final answer:
To calculate the speed of the car when it drove off the cliff, we used projectile motion equations to solve for the time it took to hit the ground and then found the horizontal velocity with this time and the given horizontal distance.
Explanation:
To determine the speed at which the car was traveling when it went off the cliff, we can use the kinematic equations for projectile motion. Given that the car falls from a height of 40.8 m and lands 121 m away from the base of the cliff, we can first calculate the time it took for the car to hit the ground using the equation for vertical motion under constant acceleration due to gravity (g = 9.8 m/s²). The vertical motion is independent of the horizontal motion, so:
y = ½ gt², where y is the vertical displacement and t is the time.
Using this equation, we solve for t:
40.8 m = ½ (9.8 m/s²) t²
t = √((2 * 40.8 m) / 9.8 m/s²)
After calculating the time, t, we can then use the horizontal distance travelled and the time of flight to find the horizontal velocity (v):
x = v * t, where x is the horizontal displacement.
Now we substitute the previously calculated time t in the equation to find the horizontal velocity (which is also the initial velocity since there is no horizontal acceleration):
v = x / t
v = 121 m / t
This gives us the car's speed as it left the cliff.

so the acceleration of free fall is always constant and given as
[tex]a = \frac{F}{m}[/tex]
[tex]a = \frac{mg}{m}[/tex]
[tex]a = g[/tex]

If weight is a measure of an object's force due to gravity, what is the weight of a student who has a mass of 65 kg? (assume that the acceleration due to gravity equals 9.8 m/s2.)
The weight of the object with mass 65kg and acceleration due to gravity 9.8 m/s² is 637N.
What is Weight?
The weight (w) of an object is the product of its mass (m) in kilograms and the acceleration due to gravity, g in meters per second square. The weight of an object in physics is the force which is acting on the object due to the gravity of the planet. The SI unit of weight is newton (N).
The weight of the object is:
W = m × g
where, W = weight of the object,
m = mass of the object,
g = acceleration due to gravity,
m = 65 kg,
g = 9.8m/s²
W = 65 × 9.8
W = 637N
Therefore, the weight of the object is 637N.

b. what was the Dependant variable ?
c. what was the control group?
d. was there a controlled variable?
e. if yes, explain
Answer:
The independent variable is the variable in the experiment which can be manipulated or changed in an experiment, the effect of such change can be observed on the dependent variable. The dependent variable is the one which cannot be manipulated in the experiment and changes occurring in the dependent variable is because of affect of the changes in the independent variable. The control group is the group of the experimental study that does not receive treatment by the researchers. A control variable is the variable which remains constant and does not change in the experiment.
a. The dependent variable is the growth of bacteria.
b. The independent variable is the penicillin.
c. The control group is the paper circle which is not treated with penicillin.
d. The controlled variable is the paper not treated with penicillin.
e. The growth of bacteria is the dependent variable because it dependents upon the absence or presence of the penicillin. In the paper circle that lacks the penicillin shows the growth of bacteria and the paper circle socked with penicillin the growth of bacteria does not occur because it is an antibiotic which kills bacteria.
The penicillin is the independent variable because the effect of this can be observed on bacterial growth.

How do the base pairing rules relate to chargaff's rule?
Final answer:
Chargaff's rule, which states that in DNA, the amount of adenine equals thymine and guanine equals cytosine, directly supports the base pairing rules necessary for DNA's double helix structure and its replication.
Explanation:
The base pairing rules and Chargaff's rule are intimately connected in explaining the structure and function of DNA. Erwin Chargaff discovered that in any given DNA molecule, the amount of adenine (A) is approximately equal to thymine (T), and the amount of guanine (G) is approximately equal to cytosine (C). This observation is now known as Chargaff's rule. It was a pivotal finding that helped James Watson and Francis Crick determine the double helix structure of DNA.
They uncovered that A pairs with T through two hydrogen bonds, and G pairs with C through three hydrogen bonds, adhering to the base pairing rules. This complementary base pairing ensures that DNA can replicate and transfer genetic information accurately.
