The frequency of an event is the inverse of time period.The frequency of the kid on bouncing the pogo stick is 1.47 Hz.

Frequency of an event is is the number of occurance of that event in unit time. It is the inverse of time period of that event. Hence frequency has the unit of s⁻¹ which is equivalent to Hz.

The frequency of a wave is the number of wave cycles per unit time. Frequency is directly related to the energy of the vibration or wave. Hence, as the frequency increases, energy increases.

Given that, the number of oscillations from the bouncing of the pogo stick is 22 times in 14.9 seconds. Thus , number of oscillations in 1 second is:

22 /14.9 s = 1.47 Hz.

Therefore, the frequency of the event created by the kid is 1.47 Hz.

Answer:

Three types of electromagnetic waves, used to transmit various information

Explanation:

A form of energy waves having both electric & magnetic fields are Electromagnetic waves. Three types -

Radio Waves - These have longest wavelengths & transmit data through radio, satellites, radar .

Micro Waves - These have shorter wavelengths & are used in cooking appliances & predicting weather.

X rays - These have more short wavelength and can penerate soft tissues like skin & muscle, hence are used for medical examining

Answer:

Three types of electromagnetic waves that are commonly used to transmit information are:

Radio Waves:

Radio waves are used for transmitting radio signals, television signals, and wireless communication. They are received by devices such as radios, televisions, and mobile phones with radio receivers.

Microwaves:

Microwaves are used for various purposes, including satellite communication, microwave ovens, and wireless data transmission. They are received by devices such as microwave antennas, satellite receivers, and Wi-Fi routers.

Light Waves (Optical Waves):

Light waves, specifically in the form of optical waves, are used for fiber optic communication, which involves transmitting data through optical fibers. They are received by devices such as optical receivers, which convert the light signals back into electrical signals for processing.

Each type of wave requires specific devices to receive and interpret the transmitted information effectively.

Answer:

We conclude that the required momentum is 80 kgm/s.

Explanation:

Given

To determine

The momentum p = ?

Important Tip:

We can determine the momentum using the formula

[tex]p = mv[/tex]

where

now substituting m = 20 and v = 4 using the equation

[tex]p = mv[/tex]

[tex]p = (20) (4)[/tex]

[tex]p = 80[/tex] kg m/s

Therefore, we conclude that the required momentum is 80 kgm/s.

The momentum of the moving cart is 80kgm/s.

HOW TO CALCULATE MOMENTUM:

Momentum (p) = mass (m) × velocity (v)

Momentum (p) = 20kg × 4m/s

Momentum (p) = 80kg*m/s.

Since the bell is at rest in an elevated position, we can assume that it only has potential energy.

U=mgh is the formula for potential energy where U=potential energy, m= mass, g=acceleration due to gravity, and h=height.

Plug in known variables....

U=200kg*9.8m/s^2*45m

U=88200 joules of potential energy or letter D.

The arrow A represents the direction of upthrust.

Thrust is the pressure acting generally on a surface. Its SI unit is Newton (N). Thrust is the pressure that actions a plane via the air. Thrust is used to triumph over the drag of an airplane, and to conquer the load of a rocket.

As anxiety is the significance of pressure, it is measured in newtons (or now and again kilos-force) and is usually measured parallel to the string on which it applies. Thrust is a response pressure defined quantitatively by means of Newton's.

Answer:

b is correct!!!!!!!!!!!

The best transport electrons around an electrical circuit are connected in series. Thus, the correct answer would be option (B) are connected in series.

An alternating current (AC) circuits continuously switches the direction of electron flow back and forth, which can result in fluctuations in voltage and current.

On the other hand, in a direct current (DC) electrical circuit, the electrons flow in one direction, from the negative terminal of the power source to the positive terminal. This unidirectional flow of electrons provides a consistent and stable flow of electricity throughout the circuit.

Connecting components in series mean that they are connected end-to-end, and the current flowing through them is the same.

Overall, the best option to transport electrons around an electrical circuit are to connect in series.

Therefore, the correct answer would be option (B) are connected in series.

Explanation:

From the question,

Speed (S) = Distance(d)/Time(t)

S = d/t....................... Equation 1

Make d the subject of the equation

d = St..................... Equation 2

Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds

Substitute these values into equation 2

d = 50000(300)
