Ruhi drew many designs on a card and held it up in front of a mirror. One of the designs did not look exactly the same when she looked at it in the mirror. But the other 3 designs looked exactly the same. Which of the following will look different when seen in the mirror?
The design that will look different in a mirror is the one that is not completely symmetrical.
A mirror is a surface or object that reflects images. This reflection is not identical to reality because the image is inverted and therefore a virtual rather than a real image is created.
This implies, we perceive the image as being left-right inverted. In this context, if a design is symmetrical it will look identical in the mirror, but if it is not symmetrical, especially if its right or left sections are different the reflection will not be identical.
Note: This question is incomplete because the designs are missing; due to this, I answered it based on general knowledge.

Answer: Earthquakes and Volcanic eruptions
Explanation:
You did not attach a picture however, this should be the correct answer.
Mid-oceanic ridge plate boundaries such as the Mid-Atlantic Ridge form as a result of plate separating at the boundary. This leads to earthquakes due to the forces of tension acting on the plates.
When this happens, the mantle is exposed and therefore there will be volcanic eruptions as the lava comes to the surface as magma. When this magma cools it creates new seafloors and underwater mountains.

Consider two cars, with the second car having a mass six times the mass of the first car. Compare the kinetic energy of each car. Then describe the implications of your answer for using brakes to bring each car to a complete stop.
Answer:
The kinetic energy of an object is directly proportional to its mass and the square of its velocity. This means that if the mass of an object is increased, its kinetic energy will also increase.
In the case of the two cars, the second car has a mass six times the mass of the first car. This means that the kinetic energy of the second car will be six times greater than the kinetic energy of the first car.
Therefore, the implications of the second car having six times the kinetic energy of the first car is that it will require more force and heat energy to bring it to a stop using the brakes. This may require the use of more advanced braking systems, such as brakes with larger calipers or brake discs, in order to effectively stop the car in a safe and timely manner.

(a) What is the applied force required to move the bar to the right with a constant speed of 6.00 m/s? (b) At what rate is energy dissipated in the 4.00 ? resistor?
A). To move the bar to the right with a constant speed of 6.00 m/s, we need to find the force required. The force required is the force of the magnetic field that acts on the bar. The power dissipated in the resistor is 6.98 W.
This force is given by the formula: F = BILsinθwhere,F is the force B is the magnetic field I is the current L is the length of the conductorθ is the angle between the magnetic field and the current direction Now, the current in the bar is given by: I = V/R where, V is the voltage applied across the resistor R is the resistance of the resistor Given, V = BLV/Rsinθwhere,L = 1.6 m B = 2.20 T, and R = 4.00 ?θ = 90° = π/2 radians So, V = 2.20 × 1.6 × 6.00/4.00 = 5.28 V The current in the circuit is, I = V/R = 5.28/4.00 = 1.32 A
Therefore, the force required is: F = BILsinθ = 2.20 × 1.6 × 1.32 × 1 = 4.3872 N(b) The power dissipated in the resistor is given by: P = VI where, V is the voltage applied across the resistor I is the current in the circuit From the above calculations, V = 5.28 VI = 1.32 AP = VI = 5.28 × 1.32 = 6.98 W

how to find the frequency of light with a wavelength
The frequency (f) can be calculated by dividing the speed of light (c) by the wavelength (λ):
f = c / λ
To find the frequency of light given its wavelength, you can use the formula:
frequency = speed of light / wavelength
where the speed of light is approximately 3.00 x \(10^8\) meters per second (m/s).
So, the frequency (f) can be calculated by dividing the speed of light (c) by the wavelength (λ):
f = c / λ
Make sure to use consistent units for the speed of light and wavelength. For example, if the wavelength is given in meters, use meters for the speed of light as well.
Keep in mind that frequency is measured in hertz (Hz), which represents the number of cycles per second.

A bowling ball of mass 10.2 kg moves in a
straight line at 3.03 m/s.
How fast must a Ping-Pong ball of mass
3.309 g move in a straight line so that the two
balls have the same momentum?
Answer in units of m/s.
Answer:
v = 9341.19 [m/s]
Explanation:
Linear momentum is defined as the product of mass by Velocity. In this way by means of the following equation, we can calculate the momentum.
\(P=m*v\)
where:
P = momentum [kg*m/s]
m = mass = 10.2[kg]
v = velocity = 3.03 [m/s]
Now replacing, we have:
\(P=10.2*3.03\\P = 30.91 [kg*m/s]\)
Now the ping-pong mass is 3.309 [g] or 0.003309 [kg]
We can clear the value for v from the equation above.
\(v = P/m\\v = 30.91/0.003309\\v = 9341.19 [m/s]\)
15) A car is moving when the driver sees a signal light 40 m ahead turn red. The car can slow with a -.5g, where g is 9.8 m/s^2.. What is her stopping distance assuming
(a) zero reaction time?
(b) A reaction time of 0.20 s between when she sees the red light and when she hits the brake.
The stopping distance is 0 m if the driver has zero reaction time and the stopping distance is 1600 m if the driver has a reaction time of 0.20 s.
What is distance?Distance is the measure of how far apart two objects are in space. It is a physical quantity that is the length between two points or objects. Distance is usually measured in meters, kilometers, or miles. Distance is a scalar quantity that only has magnitude, not direction. It is the length of a line that connects two points. Distance can be measured in a straight line or along a curved path.
a) Zero Reaction Time:
The stopping distance is equal to the distance traveled during the time it takes for the car to come to a stop. Since the car has a negative acceleration of -0.5g, we can use the equation d = (v^2)/2a to calculate the stopping distance.
d = (v^2)/2a
d = (0^2)/2(-0.5g)
d = 0 m
Therefore, the stopping distance is 0 m if the driver has zero reaction time.
b) Reaction Time of 0.20 s:
The stopping distance is equal to the distance traveled during the time it takes for the car to come to a stop. Since the car has a negative acceleration of -0.5g, we can use the equation d = (v^2)/2a to calculate
the stopping distance.
d = (v^2)/2a
d = (40^2)/2(-0.5g)
d = 1600 m
Therefore, the stopping distance is 1600 m if the driver has a reaction time of 0.20 s.

A class A pan is maintained near a small lake to determine daily evaporation (see table). The level in the pan is observed at the end of everyday. Water is added if the level falls near 5 inches. For each day the difference in the height level is calculated between the current and previous day. And the precipitation value is from the current day. Determine the daily lake evaporation if the pan coefficient is 0.7.
To calculate the daily lake evaporation, multiply the pan coefficient (0.7) by the difference in the height level between the current and previous day, then subtract the precipitation value for the current day.
The class A pan measures evaporation, and the pan coefficient is used to account for differences between the pan and the lake. By multiplying the pan coefficient by the change in water level and subtracting precipitation, you get an accurate estimate of the daily lake evaporation.
After calculating the pan evaporation for each day, we can sum up the values to find the total evaporation for the time period covered by the table. This will give us the daily lake evaporation that was requested in the question. The question is determining the daily lake evaporation if the pan coefficient is 0.7, using the observed level in a class A pan and the given precipitation value.

A bungee jumper is a person who jumps off a platform or a tall structure while attached to a bungee cord. The un-stretched length of the bungee cord refers to its length when it is not stretched or extended. Energy transfers refer to the transfer of energy from one form to another, such as from potential energy to kinetic energy or vice versa.
19) When the bungee jumper starts to jump, he has potential energy due to his position above the ground. As he jumps, this potential energy is converted into kinetic energy, which is the energy of motion. At position a, the jumper has all potential energy and no kinetic energy. At position b, he has some potential energy and some kinetic energy. At position c, he has no potential energy and all kinetic energy. The energy bar charts would show the amount of potential and kinetic energy at each position.
20) The energy transfer from position a to b is the transfer of potential energy to kinetic energy. The energy transfer from position b to c is the transfer of kinetic energy back to potential energy as the bungee cord stretches and slows the jumper down.
21) The energy conservation equation is: Potential energy at start = Kinetic energy at stopping point + Potential energy stored in the stretched bungee cord. This equation takes into account that the potential energy is converted into kinetic energy during the jump, and then back into potential energy as the bungee cord stretches and slows the jumper down.
22) Solving for the stretched length AL of the bungee cord would involve using the equation for the potential energy of the bungee cord, which is given by: Potential energy = (1/2)k(AL-L)^2. We would need to use the energy conservation equation to find the total potential energy at the stopping point and then equate it to the potential energy of the bungee cord. We would then solve for AL, the stretched length of the bungee cord.

rolls of foil are 308 mm wide and 0.013 mm thick. (the density of foil is 2.7 g/cm3 .) what maximum length of foil can be made from 1.35 kg of foil?
The maximum length of foil that can be made from 1.35 kg of foil is approximately 12487.51 cm.
We are given the width, thickness, and density of the foil, and we need to find the maximum length of foil that can be made from 1.35 kg. We can start by calculating the volume of the foil, then use that to find the length.
Convert mass to grams.
1.35 kg = 1350 g
Calculate the volume of the foil.
Volume = Mass / Density
Volume = 1350 g / 2.7 g/cm³
Volume ≈ 500 cm³
Convert width and thickness to centimeters.
Width = 308 mm = 30.8 cm
Thickness = 0.013 mm = 0.0013 cm
Calculate the cross-sectional area of the foil.
Area = Width × Thickness
Area = 30.8 cm × 0.0013 cm
Area ≈ 0.04004 cm²
Calculate the maximum length of the foil.
Length = Volume / Area
Length ≈ 500 cm³ / 0.04004 cm²
Length ≈ 12487.51 cm
Therefore, approximately 12487.51 cm is the maximum length of foil that can be made from 1.35 kg of foil.

a water line starts the service with an altitude of 1200m over the sea level, what is the velocity of the water above 1050 m over the sea level?
Answer:
Velocity = 94.85m/s
Explanation:
Given the following data ;
Height = 1200m
Vertical distance = 1050m
To find the time, we would use the second equation of motion;
\( S = ut + \frac {1}{2}at^{2}\)
Substituting into the equation, we have;
\( 1200 = 0(t) + \frac {1}{2}*9.8*t^{2}\)
\( 1200 = 0 + 4.9*t^{2} \)
\( 1200 = 4.9*t^{2} \)
\( t^{2} = \frac {1200}{4.9} \)
\( t = \sqrt{122.45}\)
t = 11.07 secs
To find the velocity;
Mathematically, velocity is given by the equation;
\(Velocity = \frac{distance}{time}\)
Substituting into the above equation;
\(Velocity = \frac{1050}{11.07}\)
Velocity = 94.85m/s
Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.

a 0.48-kg piece of wood floats in water but is found to sink in alcohol in which it has an apparent mass of 0.047 kg. what is the sg of the wood?
The specific gravity of wood is 0.853, which allows for an apparent mass of 0.047 kg of wood to sink in alcohol.
Mass of wood = 0.48 kg
It floats on water. So ? wood Alcohol apparent mass equals 0.035 kilogramme
Loss in mass = 0.48 - 0.035 = 0.445 kg = mass of alcoholdisplaced
Volume of alcohol displaced = 0.445/790 = 5.63×\(10^{-4}\) \(m^{3}\) = Volume of wood
Density of wood = Its mass / volume = 0.48/5.63×\(10^{-4}\) = 853 kg \(m^{-3}\)
Wood's specific gravity is equal to its density divided by the density of water, which is
= 853 /1000
= 0.853
Technically speaking, specific gravity is a measurement of the density of wood in relation to water. (So the specific gravity of a piece of wood would be 1.00 if it has the same density as water.) The moisture level of the wood has a significant impact on the density measurement, as it does with all measurements of density for wood. The more moisture the wood has, the denser it will be.
