The frequency of the sound will be 500 Hz. The frequency of the sound is the inverse of the time period.

A sound pressure wave's frequency, also known as pitch, is the number of times it repeats itself every second.

The frequency of the sound is the inverse of the time period. The frequency is given as;

[tex]\rm f= \frac{1}{t} \\\\ \rm f= \frac{1}{0.002 } \\\\ \rm f= 500 \ Hz[/tex]

Hence the frequency of the sound will be 500 Hz.

Answer: Ernest Rutherford's

Answer:

Distance, d is 86.1 meters.

Explanation:

Given the following data;

Time, t = 6.15secs

Velocity = 14m/s

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

[tex]V = \frac{d}{t}[/tex]

[tex]d = Vt[/tex]

Substituting into the above equation;

[tex]d = 14 * 6.15[/tex]

d = 86.1m

Hence, the distance traveled by the boat is 86.1 meters.

An asteroid is a type of space rock, much smaller than a planet, and moves in an elliptical orbit around the Sun.

It is a smaller body that is part of the solar system and has a diameter of less than 1,000 kilometers.

Asteroids are the subject of constant study due to the proximity they maintain to Earth, despite the fact that the chances of their impacting are very low despite the fact that they have reached the planet in a very remote past.

Therefore, we can conclude that asteroids are characterized by having a very weak gravitational force, they are celestial bodies that orbit around the Sun, and that they are remnants of the matter that gave rise to the Solar System.

Answer:

The vertical distance that the ski jumper fell is 417.45 m.

Explanation:

Given;

initial horizontal velocity of the jumper, [tex]V_x[/tex] = 26 m/s

horizontal distance of the jumper, dx = 240 m

The time of the motion is given by;

dx = Vₓt

t = dx / Vₓ

t = 240 / 26

t = 9.23 s

The vertical distance traveled by the diver is given by;

[tex]d_y = V_yt + \frac{1}{2}gt^2[/tex]

initial vertical velocity, [tex]V_y[/tex], = 0

[tex]d_y = \frac{1}{2}gt^2\\\\d_y = \frac{1}{2}(9.8)(9.23)^2\\\\d_y = 417.45 \ m[/tex]

Therefore, the vertical distance that the ski jumper fell is 417.45 m.

Answer:

The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.

Explanation:

The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cellular respiration begins in the cytoplasm with glycolysis

Explanation:

V² = Vx² + Vy²

= [3.14 cos(30)]² + [2.71 cos(300)]²

= 9.23

V = root 9.23 = 3.038

Answer: 1.5 km/s²

Explanation:

Given that,

Initial speed Vi = 0 km/s

Final speed Vf = 12km/s

Acceleration A = ?

Time taken T = 8 seconds

Recall that acceleration is the rate of change of velocity per unit time

i.e acceleration = (Vf - Vi)/T

A = (12km/s - 0km/s) / 8 seconds

A = 12km/s / 8 seconds

A = 1.5 km/s²

Thus, the acceleration of the rocket is 1.5 km/s²

Depending on the research you find, it could vary. Explain to them that while watching TV is not an "evil" thing, it can have some effects in the youth. Tell them how it can affect the behavior with friends, family and other people whom are around them. In addition you could even as far as mentioning academic success and failure. Studies confirmed that the television media influences children behavior since early ages. It is extremely prejudicial to expose young children to television for many reasons such as: underdevelopment, optical issues, brain damage, difficulty of learning, speaking and obesity.By the time these kids become adolescents they are obese, sedentary, with heart illness and other psychological disorders. The exposure to violence,  are also damaging for their mental healthy and behavior. Kids that spend great part of their time watching tv or playing video games are more susceptible to depression and mental diseases. In order to avoid these pathologies, children must be encourage to play outside and practice sports.

Watching television is very much informative on one side if we use it effectively but the prolonged use and involving more in entertainments definitely  affects the academics of students and even in their behavior badly.

By the time they turn 15, the typical child born today will have spent more time watching television than in school. According to research, watching a lot of violent TV is linked to the emergence of aggressive attitudes and actions.

Television seems to encourage stereotypes about race and gender roles as well. Last but not least, television advertisements frequently prey on kids' innocence and can encourage and promote excessive materialism.

All of these negative effects can be lessened if parents limit their children's overall television consumption, support some shows while discouraging others, and constantly discuss the meaning of what they see with them.

It is challenging to assert that television programming has no impact on young people. Yet, it is similarly challenging to isolate individual shows or programming genres as the root of certain behaviors in kids without taking into account the countless alternative influences that might have an impact on their behavior.

The efficiency of the torch light from the total energy supplied and useful energy is 46.7%.

The efficiency of the torch is the amount of energy used to produce light compared to the total energy supplied to the torch light. This can also be called useful energy.

Total energy supplied to the torch = 150 J

Total energy used to produce light = 70 J

The efficiency of the torch light is calculated as follows;

Efficiency = 70/150 x 100%

Efficiency = 46.7%

Thus, the efficiency of the torch light from the total energy supplied and useful energy is 46.7%.

Explanation:

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.
