The speed of the wind from the east with 3.7 m/s is pushing the paper airplane that flies with a velocity of 1.5 m/s north. Then the resultant velocity of the plane is 3.9 m/s.

Velocity is a physical quantity measuring the distance travelled by an object per unit time. It is a vector quantity thus characterized by a magnitude and direction.

The velocity of an object moving north relative to wind towards east can be expressed as a resultant velocity or relative velocity of the former as:

v = √v1² + v2²

Given v1 = 1.5 m/s

v2 = 3.7 m/s

then v = √1.5² + 3.7² = 3.9 m/s

Therefore, the total velocity of the paper airplane is 3.9 m/s.

The speed of light and the propagation of errors allows to find the results on the questions of the radiation emitted by the laser are:

    a) The frequency is: f = 3.7 10¹⁴ Hz

    b) The energy with its uncertainty is: E = (2.465 ± 0.004) 10⁻¹⁹ J

a) The speed of a wave is related to its wavelength and frequency.

           c = λ f

           \(f = \frac{c}{\lambda}\)

Where c is the speed of light, λ the wavelength and f the frequency.

They indicate that the wavelength is λ = 800 nm = 800 10⁻⁹ m, the speed of light is a constant c = 2.99 10⁸ m/s.

         f = \(\frac{2.99 \ 10^8}{800 \ 10^{-9}}\)  

         F = 3.7 10¹⁴ Hz

b) Planck's equation states that the energy is proportional to the frequency of the radiation.

         E = h f

Where E is the energy, h the Planck constant and f the frequency.

         E = 6.63 10⁻³⁴  3.7 10¹⁴

         E = 2.46467 10⁻¹⁹ J

The uncertainty or error is the fluctuation that a magnitude may have due to the precision in the measurements, when the magnitude is calculated by some formula, the propagation of these uncertainties must be carried out.

        Δm = ∑   \(\sum \frac{dm}{dx_i} | \Delta x_I|\)  

the expression for energy is:

        E = \(\frac{hc}{\lambda }\)  

        \(\Delta E = \frac{dE}{d \lambda} |D\lambda |\)  

        \(\Delta E = \frac{h c }{\lambda^2 } |\Delta \lambda |\)

When the error in the measured magnitude is not explicitly indicated, we assume that the error is in the last digit written, therefore

         Δλ = ± 1 nm = ± 1 10⁻⁹ m

We calculate.

        \(\Delta E = \frac{6.63 \ 10^{-34} \ 2.99 \ 10^8 }{(800 \ 10^{-9})^2} 1 \ 10^{-9}\)  

        ΔE = 3.1 10⁻²² J

the error is given with a significant figure.

        ΔE = 3 10⁻²² J = 0.004 10⁻¹⁹ J

The result of the energy is:

        E = (2.465 ± 0.004) 10⁻¹⁹ J

In conclusion, using the speed of light and the propagation of errors, we can find the results on the questions of the radiation emitted by the laser are:

    a) The frequency is; f = 3.7 1014 Hz

    b) The energy with its uncertainty is: E = (2.465 ± 0.004) 10⁻¹⁹ J

Explanation:

Option B is correct

The power delivered to the headlight is 460.8 Watts.

Power is the ability to influence others and to control resources, people and situations. It is a central concept in politics, economics and social studies, and is often defined as the ability to determine the behaviour of others.

The total energy delivered by the battery over the 8-hour discharge period can be calculated as follows:
Energy = Power x Time
Energy = 460.8 Watt-hours
To calculate the power delivered to the headlight, we first need to know the current being drawn by the headlight. Assuming that the headlight is a 12V bulb, the current can be calculated as follows:
Power = Voltage x Current
460.8 = 12V x Current
Current = 38.4 Amps
Therefore, the power delivered to the headlight is 12V x 38.4A = 460.8 Watts.

The correct answer to question:

Explanation:

When g=a, that means everything on earth fall at the same rate.

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

Answer:

a = 4 m/s2

Explanation:

Given: 200 N, 50 kg

To find: a

Formula: \(A = \frac{f}{m}\)

Solution: To find a, divide the force by the weight

A = F ÷ m

=  200 ÷  50

= 4 m/s²

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

To solve this problem, we will use the principle of conservation of mass applied to fluid flow, which states that the mass flow rate of the fluid is constant throughout the hose.

Explanation:

Mathematically, this is represented by the equation:

mass_flow_rate_in = mass_flow_rate_out

The mass flow rate can be calculated using the formula:

mass_flow_rate = area × velocity

where area = π(diameter/2)^2.

First, we need to calculate the area of the hose and nozzle:

Area_hose = π(0.016/2)^2
Area_hose ≈ 0.000201 m^2

Area_nozzle = π(0.0050/2)^2
Area_nozzle ≈ 0.0000196 m^2

Now, let's apply the conservation of mass principle:

Area_hose × velocity_hose = Area_nozzle × velocity_nozzle

We know the diameter and velocity of the hose (0.016 m and 3 m/s). We need to find the exit velocity of water from the nozzle (velocity_nozzle).

0.000201 × 3 = 0.0000196 × velocity_nozzle

Rearrange the equation to find the velocity_nozzle:

velocity_nozzle = (0.000201 × 3) / 0.0000196
velocity_nozzle ≈ 30.66 m/s

The exit velocity of water from the garden hose when a nozzle of diameter 0.0050 m is attached to the end of the hose is approximately 30.66 m/s.

The statement "longer wavelengths are affected more by a prism or water droplets than are the shorter wavelengths." is false.

In reality, shorter wavelengths are affected more by a prism or water droplets than longer wavelengths. This phenomenon is known as dispersion. Dispersion occurs because different wavelengths of light bend at different angles as they pass through a medium, such as a prism or water droplets.

When light enters a prism or encounters water droplets, it undergoes refraction, which is the bending of light as it passes from one medium to another. The degree of refraction depends on the wavelength of light. Shorter wavelengths, such as blue and violet light, are refracted more than longer wavelengths, such as red light.

This differential refraction causes the various wavelengths of light to spread out or separate from each other, resulting in the phenomenon known as dispersion. A prism can separate white light into its constituent colors, creating a rainbow-like effect. Similarly, when sunlight passes through raindrops, it undergoes dispersion, creating a rainbow.

Therefore, it is the shorter wavelengths of light that are more significantly affected by a prism or water droplets, while the longer wavelengths are relatively less affected.

A force could have direction because force is a vector quantity. We know that an object is going to remain at rest if the object is acted upon by balanced forces. According to the Newton's first law, the only time that an object would move is if the object has been acted upon by external forces.

The linear speed of a unit mass located at the inner equator of the sphere is approximately 2401.07 meters per second.

The linear speed \((\(v\))\) of a unit mass located at the inner equator of a sphere can be calculated using the formula for linear speed in a circular motion:

\(\rm \[v = \frac{{2\pi r}}{T}\]\)

where:

r = Radius of the sphere (distance from the center to the equator)

T = Time taken for one complete revolution (orbital period)

In this case, we are considering the inner equator of the sphere, which means the radius r is the same as the mean radius of the sphere. Let's denote the mean radius as \(\rm \(R_{\text{mean}}\)\).

Given:

\(\rm \(R_{\text{mean}} = 3.40 \times 10^6 \, \text{m}\)\) (given the mean radius of Mars)

The time taken for one complete revolution T can be calculated using the orbital period of Mars, which is approximately 24.6 hours. Let's convert it to seconds:

\(\rm \(T = 24.6 \, \text{hours} \times 3600 \, \text{s/hour}\\= 8.856 \times 10^4 \, \text{s}\)\)

Now, let's calculate the linear speed v:

\(\rm \[v = \frac{{2\pi R_{\text{mean}}}}{T} \\\\= \frac{{2\pi \times 3.40 \times 10^6 \, \text{m}}}{{8.856 \times 10^4 \, \text{s}}} \\\\\approx 2401.07 \, \text{m/s}\]\)

The variables for the given parcel with a temperature of 30°C and a dewpoint of 20°C at 1000mb are as follows:

i. Actual vapor pressure (e)

ii. Saturation vapor pressure (es)

iii. Actual mixing ratio (r)

iv. Saturation mixing ratio (r5)

v. Total water mixing ratio (rT)

vi. Available supersaturation (SA)

vii. Excess water mixing ratio (rF)

To calculate the variables, we can use the following equations and physical relations:

i. Actual vapor pressure (e):

We can use the Clausius-Clapeyron equation to calculate the actual vapor pressure:

e = es(T) * (rh/100)

where es(T) is the saturation vapor pressure at temperature T, and rh is the relative humidity.

ii. Saturation vapor pressure (es):

We can use the Arden Buck equation to calculate the saturation vapor pressure:

es = 6.112 * exp((17.67 * T)/(T + 243.5))

where T is the temperature in °C.

iii. Actual mixing ratio (r):

The actual mixing ratio can be calculated using the following equation:

r = (0.622 * e)/(p - e)

where e is the actual vapor pressure and p is the atmospheric pressure.

iv. Saturation mixing ratio (r5):

The saturation mixing ratio can be calculated using the following equation:

r5 = (0.622 * es)/(p - es)

v. Total water mixing ratio (rT):

The total water mixing ratio can be calculated by summing the actual mixing ratio and the excess water mixing ratio:

rT = r + rF

vi. Available supersaturation (SA):

The available supersaturation can be calculated using the following equation:

SA = (rT - r5)/r5 * 100

vii. Excess water mixing ratio (rF):

The excess water mixing ratio can be calculated by subtracting the saturation mixing ratio from the actual mixing ratio:

rF = r - r5

By using these equations and the given starting conditions, we can calculate the values of the variables mentioned above.

The calculations for the variables mentioned involve utilizing several equations and physical relations related to atmospheric thermodynamics. These equations are derived from fundamental principles and empirical relationships that describe the behavior of water vapor in the atmosphere. By applying these equations to the given conditions, we can determine values such as actual vapor pressure, saturation vapor pressure, actual mixing ratio, saturation mixing ratio, total water mixing ratio, available supersaturation, and excess water mixing ratio. These variables provide valuable information about the moisture content and saturation levels of the parcel of air being analyzed. Each equation serves a specific purpose in quantifying these properties and allows for a comprehensive understanding of the thermodynamic state of the parcel.
