The wavelength of these radio waves are 2.88 m

In the electromagnetic spectrum, radio waves have the longest wavelengths. These waves, which fall under the category of electromagnetic radiation, range in frequency from 300 GHz to 3 kHz, though they are sometimes classified as microwaves above 3 GHz.

The given frequency is 104 mhz

Any radiation in the electromagnetic spectrum, including radio waves, travels at a speed of 3.00 x 10^8 m/s in vacuum.

Consequently, the following equation can be used to determine the wavelength:

c = wavelength × frequency

frequency is given in mHz thus we convert it into Hz

and get 104 × 10 ^6

this implies

wavelength = \(\frac{3 X 10^8}{104 X 10^6}\)

wavelength = 0.0288× \(10^{2}\) m

= 2.88 m

If a ball is thrown vertically upwards with an initial velocity V 0 then here is a set of formula for your quick reference. 1) Maximum height reached = H = V 02 / (2 g) 2) Velocity at the highest point = 0 3) Time for upward movement = V 0 /g 4)

The most general shape of the path that a charged particle, which may be moving initially in any direction will travel in a region of space is a helix shape.

A helix is a three-dimensional spiral curve. It is a type of smooth space curve with tangent lines to a given curve that continuously rotate around a central axis or point as the curve moves away from or towards the axis. In a magnetic field, the path of the charged particle is in the form of a helix, which is also known as cyclotron motion.

When a charged particle enters a magnetic field, it will experience a force perpendicular to both the direction of the field and the velocity of the particle. The particle's trajectory will be a helix, with a radius determined by the particle's velocity, charge, and the magnetic field's strength. The pitch of the helix (the distance between each turn) is determined by the ratio of the particle's velocity to the magnetic field's strength.

The distance of the motorboat relative to the home, which travels in various directions, is 3.07 km.

Relative velocity is a velocity of an object which is in respect to another observer, or it is a ratio of change in the position of a point to time with respect to another observer.

Given: Travel in East direction (\(d_{E}\))= 5 km,

velocity in N35E(v) = 2 m / s, time taken(t)  = 90 min = 5400 seconds,
Displacement in south (\(D_S}\)) = 6.5 km

Firstly, find the displacement  in N35E so

Displacement   = Velocity × time,

\(d_{NE}\) = 2 × 5400 = 10800 meters or 10.8 km

Now by using Pythagoras' theorem
We can calculate the return displacement in the south direction(\(d_{S}\)),

\(d_{S}\) = \(\sqrt{d^{2} _{NE}- d^{2} _{E } }\)
\(d_{S}\) = \(\sqrt{10.8^{2}-5^{2} }\)

\(d_{S}\) = 9.57 km

Therefore, the distance of the boat from the home (D) = \(d_S}\) - \(D_S}\)

D = 9.57 - 6.5;

Explanation:

Answer:

1.27551m

Explanation:

This is a simple energy convertion problem. Since there is no friction, and assuming no air drag and other external factors, mechanical energy should be conserved in this system.

Thus, we get:

\(KE_{initial} + PE_{initial} = KE_{final} + PE_{final}\)

We also know that the gravitational potential energy is equal to mgh, while the KE can be calculated using \(\frac{1}{2}mv^2\)

One thing to note here, is that the final KE will be 0, as there is no velocity at the end. Furthermore, we also can set the initial PE as 0 as we are looking at relative height, and at the start it is at h=0.

\(KE_{initial} = PE_{final}\)

Plugging in:

\(\frac{1}{2}*30*5^2 = 30*9.8*h\)

Solving for h, we get 1.27551m

251 atm pressure is transmitted in the hydraulic system.

According to Pascal's principle,

P₂ = P₁

⇒ F₁/A₁                                                      ( ∵ pressure = force / area)

⇒ F₁ /πr₁²

r₁ = 0.500 m /2 = 0.250 m

An applied force of 100 N to the brake pedal acts in the cylinder through a lever. This will exert a force of 500 due to the lever of the hydraulic system.

Hence, P₂ =F₁/πr₁²

                = 500 N/ π (0.250 × 10⁻²)²

                = 2.55 × 10⁷ Pa

Convert the unit of the pressure from Pa to atm

P₂ = 2.55 × 10⁷ Pa ( 1 atm /1.01325  10⁵ Pa)

Answer: 10 seconds for the car to go from a velocity of 10 m/s to 30 m/s with an acceleration of 2 m/s^2.

Explanation:

To calculate the time it takes for a car with an acceleration of 2 m/s^2 to go from a velocity of 10 m/s to a velocity of 30 m/s, we can use the equation:

time = (final velocity - initial velocity) / acceleration

In this case:

time = (30 m/s - 10 m/s) / 2 m/s^2

time = 20 m/s / 2 m/s^2

time = 10 s

Therefore, it takes 10 seconds for the car to go from a velocity of 10 m/s to 30 m/s with an acceleration of 2 m/s^2.
