The speed of the moving train is approximately 33.5 m/s.

The beat frequency is given by the difference in frequency between the two horns, which is equal to the Doppler shift in frequency due to the motion of the moving train. Using the formula for the Doppler effect, we can solve for the speed of the train:

\(f_b = f_s\dfrac{(v + v_o)}{(v + v_s)}\)

where \(f_b\) is the beat frequency, \(f_s\) is the horn frequency, v is the speed of sound, \(v_o\) is the observer's speed, and \(v_s\) is the speed of the source.

We know that \(f_s\) = 410 Hz and \(f_b\) = 35 Hz. The speed of sound in air at standard temperature and pressure is approximately 343 m/s. Since the observer is stationary, \(v_o\) = 0.

Solving for \(v_s\), we get:

\(v_s = \dfrac{(f_s + f_b)}{f_s - 1} \times v\)

\(v_s\) = ((410 Hz + 35 Hz) / 410 Hz - 1) * 343 m/s

\(v_s\) = 33.5 m/s

If the force applied on the object is in the direction of its motion, the speed of the object increases. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object.

The amount of resistance that each resistor has, in this closed circuit, given the batteries is 3 ohms.

In a closed circuit, the total resistance (R_total) is equal to the sum of the individual resistances. We can use Ohm's law to solve for the resistance of each resistor:

Resistance (R) = Voltage (V) / Current (I)

Using Ohm's law, we can solve for the total resistance (R_total) of the circuit:

= V_total / I

= 18V / 2A

= 9 ohms

Since there are three identical resistors in the circuit, we can divide the total resistance by 3 to find the resistance of each resistor:

= 9 / 3

= 3 ohms

X-rays have more energy than visible light and can pass through the human body.

X-rays are a type of electromagnetic radiation that has a shorter wavelength and higher frequency than visible light. Due to their high energy, X-rays can penetrate solid objects, including the human body. This property makes X-rays useful in medical imaging, such as X-ray radiography, computed tomography (CT) scans, and mammography.

When X-rays pass through the human body, they can be absorbed by the tissues or pass through, depending on the density of the material. Bones, for example, absorb more X-rays than soft tissues like muscle or fat, which is why they appear white in X-ray images.

While X-rays can be helpful in diagnosing medical conditions, they can also be harmful if exposure is not limited or controlled. Prolonged exposure to X-rays can damage DNA and potentially lead to cancer or other health problems.

The mass ratio which would be required to launch a single rocket into space in the most possible efficient way is that the ratio of rocket mass to fuel mass be; 1: 14.

According to the task content, it follows that the best single rockets made by humans have an initial to final mass ratio of about 15.

In essence, it follows that if the total mass initially was 15 mass units, the final mass would be 1 mass unit.

Consequently, 14 mass units must have burned as fuel in the rocket.

On this note, it follows that the mass ratio which would be required to launch a single rocket into space is; 15: 1 and this means there are 14 mass units of fuel for the 1 mass unit of actual rocket.

Answer: find the answer in the explanation

Explanation:

1.) More thermal energy will be required to raise the temperature of 2 Kg of a substance by 10°C than is required to raise the temperature of 1 Kg of the same substance by 10°C. 

Because the thermal energy depends on the mass of an object.

If the two materials are the same, then they will have the same specific heat capacity. Thermal energy can be expressed as:

H = MCØ

Where

M = mass of the body

C = specific heat capacity

Ø = change in temperature

H = thermal energy

If u substitute the two values of masses into the formula above, then, the mass of 2kg will produce higher thermal energy .

Il.) Heat causes expansion. Using kinetic theory to explain this, the molecules of solid material are in a fixed pattern, held together with strong bonds. When heat is applied to the solid, the molecules will start vibrating in their fixed position. As a result of this, the bond between the molecules begins to loss. This eventually lead to expansion of solid.

Answer:

The force on the wire increases

Explanation:

Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.

Given that the magnetic field and the wire are perpendicular, Ф = 90°

So, F = BILsin90° = BIL

Since B and L are constant, F ∝ I

So, if the current in the wire increases, the force on the wire also increases.

The distance covered by the body is 14.4 m.

Solution,

Initial velocity(u)= 0 m/s( according to Question, the body starts from rest.that's why initial velocity(u) becomes zero.

Acceleration (a)= 0.2 m/s

Time (t):

\( = 12 \: seconds\)

Now,

Applying third equations of motion:

\(s = ut + \frac{1}{2} a {t}^{2} \\ s = 0 \times 12 + \frac{1}{2} \times 0.2 \times {(12)}^{2} \\s = 0 + 14.4 \\ s = 14.4 \: metre\)

To ensure a continuous supply of water, a well must be properly constructed and maintained.                                              

This includes ensuring that the well is drilled deep enough to reach a consistent and reliable source of water, as well as ensuring that the well is properly sealed and protected from contamination. Regular maintenance, such as periodic water quality testing and well cleaning, is also important to ensure the well continues to provide safe and reliable water for years to come.
Additionally, proper well management involves maintaining the pump system, implementing water conservation measures, and protecting the recharge area to prevent over-extraction or depletion of the groundwater source.

Answer:

m=6.25kg

Explanation:

Force= mass × acceleration

50=m×8

make m subject of the formula...

m=50/8

m=6.25kg

Answer:

\(\boxed {\boxed {\sf 6.25 \ kilograms}}\)

Explanation:

According to Newton's Second Law of Motion, force is the product of mass and acceleration.

\(F= m \times a\)

We know the force is 50 Newtons and the acceleration is 8 meters per second squared. Let's convert the units to make the problem and unit cancellation easier.

1 Newton is equal to 1 kilogram meter per square second (1 kg*m/s²), so the force of 50 N is equal to 50 kg*m/s².

Now we know 2 values:

Substitute the values into the formula.

\(50 \ kg *m/s^2= m \times 8 \ m/s^2\)

Since we are solving for the mass, we must isolate the variable, m. It is being multiplied by 8 meters per square second and the inverse of multiplication is division. Divide both sides by 8 m/s².

\(\frac {50 \ kg *m/s^2}{8 \ m/s^2}= \frac{m \times 8 \ m/s^2}{8 \ m/s^2}\)

\(\frac {50 \ kg *m/s^2}{8 \ m/s^2}= m\)

The units of meters per square second (m/s²) cancel.

\(\frac {50 \ kg }{8 }=m\)

\(6.25 \ kg =m\)

The mass is 6.25 kilograms.
