calculate the eccentricity for the planet if the distance between foci is 5,000,000 km and the distance of the major axis is 299,000,000 km.
Answers
The eccentricity for the planet if the distance between foci is 5,000,000 km and the distance of the major axis is 299,000,000 km is 0.0167.
Calculation:
The eccentricity of an elliptical orbit is defined by the ratio:
e = c/a
where:
c is the distance from the center of the ellipse to either focus
e = eccentricity
a = positive for an elliptical orbit
The eccentricity can be calculated as follows:
e = 5 × 10⁶km ÷ 299 × 10⁶km
e = 0.0167
Eccentricity is also the ratio of the semimajor axis a to the distance d from the center to the directrix. Eccentricity can be represented by flattening. Eccentricity can be defined by how much a conic actually deviates from the shape of a circle.

If you place 3 spoons into hot water, one wood, one plastic, and one metal, which spoon would be most likely to transfer the heat of the water? Why?
Answers
The metal spoon would be most likely to transfer the heat of the water.
The thermal conductivity of a material determines how well it conducts heat. Metals have high thermal conductivity, followed by plastics and then woods, which have lower thermal conductivity. The thermal conductivity of a material is typically measured in watts per meter per kelvin (W/m*K).
For example, the thermal conductivity of stainless steel is around 16 W/mK, while the thermal conductivity of plastic is around 0.2 W/mK, and wood is around 0.1 W/m*K.
Therefore, when the three spoons are placed in hot water, the metal spoon will conduct the heat from the water more efficiently than the plastic and wood spoons due to its higher thermal conductivity.
In conclusion, the metal spoon would be most likely to transfer the heat of the water due to its high thermal conductivity. The plastic spoon would be the least likely to transfer heat, followed by the wood spoon.

Shiprock has a latitude of 36.78o. On the equinoxes (the start of spring and autumn), this is also the angle of the sunlight falling on Shiprock. In the applet, set the slider to this angle. What is the relative intensity?
Answers
At a latitude of 36.78° on the equinoxes, the relative intensity of sunlight falling on Shiprock can be determined using the given angle.
The relative intensity of sunlight refers to the amount of solar radiation received at a specific location and angle compared to the maximum intensity received when the Sun is directly overhead (at a 90° angle). In this case, Shiprock's latitude of 36.78° is also the angle of sunlight falling on it during the equinoxes (the start of spring and autumn), as mentioned.
When the Sun's rays are perpendicular to the Earth's surface (at a 90° angle), the intensity of sunlight is at its maximum. As the angle of incidence decreases, the intensity of sunlight decreases. To determine the relative intensity, it is necessary to compare the angle of incidence at Shiprock (36.78°) to the angle of maximum intensity (90°).
The relative intensity can be calculated using the formula: relative intensity = cos(angle of incidence). Plugging in the given angle (36.78°) into the cosine function, we can determine the relative intensity of the sunlight falling on Shiprock during the equinoxes.

At the local destruction derby a 400 kg Toyota moving at 10 m/s collides with an 800 kg Chevy. Both are at rest after the collision. What was the velocity of the Chevy before the collision?
Answers
Answer:
\(u_2 = -5m/s\)
Explanation:
Given
Before Collision
Toyota
\(mass = m_1 = 400kg\)
\(iniital\ velocity = u_1 =10m/s\)
Chevy
\(mass = m_2=800kg\)
\(initial\ velocity = u_2 = ??\)
After Collision
Both Toyota and Chevy
\(final\ velocity = v = 0m/s\)
Required
Determine the initial velocity of Chevy
This question will be answered using the following law of conservation of momentum which states that:
\(m_1u_1 + m_2u_2 = (m_1 + m_2)v\)
Substitute values for m1, m2, u1 and v
\(400 * 10 + 800 * u_2 = (400 + 800) * 0\)
\(4000 + 800u_2 = (1200) * 0\)
\(4000 + 800u_2 = 0\)
Collect Like Terms
\(800u_2 = 0 - 4000\)
\(800u_2 = -4000\)
Divide through by 800
\(\frac{800u_2 = -4000}{800}\)
\(u_2 = \frac{-4000}{800}\)
\(u_2 = -5m/s\)
The velocity of Chevy before collision was 5m/s in the opposite direction of Toyota
if the temperature of a star doubles and all other properties remain constant, how does its spectrum and flux change?
Answers
If the temperature of a star doubles while all other properties remain constant, its spectrum shifts towards shorter wavelengths (bluer) and its flux increases by a factor of 16.
When the temperature of a star doubles while other properties remain constant, its spectrum undergoes a shift towards shorter wavelengths, meaning it becomes bluer. This shift is due to the relationship between temperature and the peak wavelength of radiation emitted by a black body, known as Wien's displacement law. Additionally, the star's flux, which is the amount of energy emitted per unit area, increases by a factor of 16. This increase is a result of the Stefan-Boltzmann law, which states that the total energy radiated by a black body is proportional to the fourth power of its temperature. Thus, doubling the temperature leads to a 16-fold increase in the star's flux.

A truck enters a highway driving 60 mph A car enters the highway at the same place 0 nutes later and dives 72 mph in t The car will pass the truck in (Round to the nearest minute) minutes same direction From So the car enters the highway,However, this contradicts the information given that the car enters the highway 0 minutes later than the truck.
To determine how long it will take the car to pass the truck, we can set up an equation based on their relative speeds and distances traveled.
Let's assume that the car passes the truck after time 't' minutes.
In 't' minutes, the truck will have traveled a distance of 60 × (t/60) = t miles.
The car enters the highway 0 minutes later and travels at a speed of 72 mph. Therefore, when the car passes the truck, it will have traveled a distance of 72 × (t/60) = 1.2t miles.
To find when the car passes the truck, we can set up the following equation:
t = 1.2t
Simplifying the equation, we get:
t - 1.2t = 0.2t
0.2t = 0
This equation does not yield a valid solution since it implies that the time required for the car to pass the truck is 0 minutes. However, this contradicts the information given that the car enters the highway 0 minutes later than the truck.

Answers
In the photoelectric effect, the higher the frequency of the illuminating light on the metal surface, the greater the energy of the emitted electrons, not the greater their number.
The photoelectric effect refers to the phenomenon where electrons are emitted from a metal surface when it is illuminated by light or electromagnetic radiation. The energy of the incident photons plays a crucial role in determining the kinetic energy of the emitted electrons.
According to the photoelectric effect, if the frequency (or energy) of the incident light is below a certain threshold value (known as the "threshold frequency"), no electrons are emitted regardless of the intensity of the light. However, once the frequency of the incident light exceeds the threshold frequency, electrons are emitted, and their kinetic energy depends on the difference between the energy of the incident photons and the energy required to overcome the binding forces holding the electrons within the metal.
The energy of a photon is directly proportional to its frequency. Therefore, higher-frequency (higher-energy) photons carry more energy. When these high-frequency photons interact with the metal surface during the photoelectric effect, they can transfer more energy to the electrons, resulting in greater kinetic energy of the emitted electrons.
In summary, the higher the frequency (energy) of the illuminating light in the photoelectric effect, the greater the energy (kinetic energy) of the emitted electrons.
