A negative velocity occurs when an object moves in the negative direction.

Example of negative velocity;

If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion. Thus, the acceleration of the object will be negative.

Huge fragments of the newly discovered comet Shoemaker-Levy 9 (SL9) collided with Jupiter over a period of days from July 16 to 22, 1994, leaving vast, dark scars in the planet's atmosphere and lofting superheated plumes into its stratosphere.

Dust was also left floating on top of Jupiter's clouds after the collision. The movement of the planet's dust allowed researchers to trace Jupiter's high-altitude winds for the first time.

The bicyclist needs to move backward by a distance of 0.2744 m to reach the nearest point of destructive interference.

The wavelength of the sound wave produced by the horns can be calculated as;

λ = v/f

λ = 343/625

λ = 0.5488 m

let the integer multiple of the wavelength = d

d = mλ

d = 4.50 + x

where;

4.50 + x = mλ

4.50 + x = m(0.5488)

let the odd multiple of half the wavelength = d'

d' = (2n + 1)(λ/2)

d' = 4.50 - y

where;

4.50 - y = (2n + 1)(λ/2)

4.50 - y = (2n + 1)(0.2744)

mλ = 2n(λ/2) + (λ/2) + 4.50 - y

x - y = (2n + 1)(λ/2) - 4.50

x - y = (2n + 1)(0.2744) - 4.50

Explanation:

Data obtained from the question include:

Mass of satellite (m) = 220 Kg

Force (F) of gravity =?

The force of gravity exerted on the satellite on the surface of the earth can be obtained by using the following formula:

Force (F) of gravity = mass (m) × acceleration due to gravity (g)

F = mg

Mass of satellite (m) = 220 Kg

Acceleration due to gravity (g) = 9.8 m/s²

Force (F) of gravity =?

F = mg

F = 220 × 9.8

F = 2156 N

Thus, the force of gravity exerted on the satellite on the surface of the earth is 2156 N

According to the work-energy theorem, the net work performed by forces acting on an item equals the change in kinetic energy.

Mobility (kinetic energy) and storing mechanical energy are the two forms (potential energy).

The change there in particle's thermal energy is equal to the net work performed on the particle: W = K B - K A

The relationship between kinetic energy and an object's mass and squares of its velocity is direct: K.E. = 1/2mv². The kinetic energy is measured in kilograms-meters squared each for a second squared if the mass is measured in kg and the velocity is measured in meters per second.

Answer:

The time is 1.4 sec

The initial velocity is 10.7 m/s.

Explanation:

Given that,

Height = 10 m

Distance = 15 m

We need to calculate the time

Using equation of motion

\(s=ut-\dfrac{1}{2}gt^2\)

Put the value into the formula

\(10=0+\dfrac{1}{2}\times9.8\times t^2\)

\(t^2=\dfrac{2\times10}{9.8}\)

\(t=\sqrt{\dfrac{2\times10}{9.8}}\)

\(t=1.4\ sec\)

We need to calculate the initial velocity

Using formula of velocity

\(v=\dfrac{d}{t}\)

Put the value into the formula

\(v=\dfrac{15}{1.4}\)

\(v=10.7\ m/s\)

Hence, The time is 1.4 sec

The initial velocity is 10.7 m/s.

The sustainable yield of adult groupers that can be caught during the fishing season in year three is 4,000.

To determine the sustainable yield of adult groupers for the fishing season in year three, we need to consider the surplus for that year. According to the information provided, the surplus for year three is 1.8 thousand (or 1,800).

The sustainable yield represents the number of adult groupers that can be caught while maintaining the population at a stable level. In this model, the sustainable yield is equal to the sum of the population and surplus for the corresponding year.

For year three, the population is constant at 2.2 thousand, and the surplus is 1.8 thousand. Adding these values together gives us:

Sustainable Yield = Population + Surplus = 2.2 + 1.8 = 4 thousand (or 4,000)

Therefore, the sustainable yield of adult groupers that can be caught during the fishing season in year three is 4,000.

The whole surface of hollow sphere = 4π r²

= 4 x 3.14 x (10 x 10⁻²)²

= 12.56 x 10⁻² m²

Area of the hole ( both side ) = 2 x π r²

= 2 x 3.14 x (10⁻³)²

= 6.28 x 10⁻⁶ m²

flux coming out of given charge at the centre as per Gauss's theorem

= q / ε₀ where q is charge at the centre and  ε₀ is permittivity of the medium .

= 10 x 10⁻⁶ / 8.85 x 10⁻¹²

= 1.13 x 10⁶

This flux will pass through the surface of sphere so flux passing through per unit area

= 1.13 x 10⁶ / 12.56 x 10⁻²

= 8.99 x 10⁶ weber per m²

flux through area of hole

=  8.99 x 10⁶ x 6.28 x 10⁻⁶

= 56.45 weber .

a. A high-pitch wave is characterized by a high frequency and a short wavelength. The frequency determines the pitch of the sound, with higher frequencies corresponding to higher pitches.

The wavelength is the distance between two consecutive peaks or troughs of the wave and is inversely proportional to the frequency. Therefore, a high-pitch wave has a shorter wavelength.

The amplitude of the wave, which is the height of the peak or the depth of the trough, is not directly related to the pitch of the sound, but it does determine the volume or intensity of the sound.

b. A high-volume wave is characterized by a high amplitude and a relatively long wavelength. The amplitude determines the volume or intensity of the sound, with higher amplitudes corresponding to louder sounds.

The wavelength of the wave does not directly affect the volume of the sound, but it can affect how the sound is perceived in different environments.

In general, longer wavelengths are more effective at traveling through obstacles such as walls and are better at penetrating long distances, whereas shorter wavelengths are more easily scattered and attenuated in the atmosphere.

Explanation:

The changing mean drift velocity of the electrons plays out at 3.506 x 10⁻⁷ m/s along with an average acceleration nearing 4.38 x 10⁻¹⁵ m/s².

As the electrons traverse one end of the wire to another, their mean drift velocity undergoes a shift of 3.506 x 10⁻⁷ m/s with an average acceleration of 4.38 x 10⁻¹⁵ m/s² in accordance with the following parameters:

- The current flowing through the wire is at 4.00 mA.

- The original diameter of the wire, d₁, measures at 4 mm or 0.004 m.

- Conversely, the final diameter, d₂, displays a measurement of 1 mm or 0.001 m.

- The length of the entire wire is consistent, measuring at 2 meters.

- Notably, the density of electrons present within copper reaches an estimated value of 8.5 x 10²⁸ /m³.

Calculations regarding both initial and final area coverage provided by copper must be explored along with numerical data involving the two varying drift velocities for accurate results.

Thus, we arrive at the change rate of the mean drift velocity between points in the wire as well as the plenitude of electron acceleration achieved after contemplation into the corresponding motion periods.

The horizontal speed of a dart player = 12.4 m/s

The dart hits the board 0.32 m below the height from which it was thrown.

We need to find how long it take the dart to hit the board.

Let the time taken by the dart to hit the board. Using second equation of motion to find it.

\(y=ut+\dfrac{1}{2}at^2\\\\\text{Put u = 0 and a= -g}\\\\y=\dfrac{-1}{2}gt^2\\\\-0.32=\dfrac{-1}{2}\times 9.8t^2\\\\t=\sqrt{\dfrac{2\times 0.32}{9.8}}\\\\t=0.255\ s\)

Let x be the horizontal distance travelled. It is calculated as follows :

\(x=12.4\times 0.255\\\\=3.16\ m\)

So, the dart will hit the board at a distance of 3.16 m.

The average highest height of a professional football kick is 189.728 m if the hang time is 4.4 seconds on average.

A person or an object's total duration in the air after leaving the ground is known as their "hang time." From the time anything leaves the ground until it returns, it is measured.

We know,

y= gt²

Here,

y = Average maximum height

g = acceleration due to gravity

t = Average hang time

Given,

Average hang time (t) = 4.4s

Acceleration due to gravity (g) = 9.8 m/s² (assuming)

Inserting these values in the given equation,

y = gt²

  = 9.8×4.4×4.4

The product of the block's mass and acceleration is the net force acting on the block. Newton's second law of motion is what is known as this.

The following is the expression for Newton's second law:

F = ma

The net horizontal force acting on the block is as follows:

Fnet =F + FcosΘ

Here, F is the force acting on the block, and 8 is the angle at which the force is applied to the block.
