The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.  

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km  

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)

v = 1463.4 Km/hr

Answer:

The carbon footprint is a very important means to understand the impact of a person's behavior on global warming. This is why someone who effectively wants to contribute to stopping global warming, at least on an individual scale, needs to measure and keep track of their personal carbon footprint.

Why is it important to track your ecological footprint?

The Ecological Footprint is a simple metric. It is also uniquely comprehensive. Not only does it measure humanity's demand on our planet's ecosystems, but it is also key to understanding the inter-related pressures of climate change on the natural ecosystems on which humanity depends.

Why is knowing your carbon ecological footprint important?

Knowing your personal or organisational carbon footprint is useful for the following reasons: it enables you to identify and reduce GG emissions, it allows corporations to publish their environmental performance statistics, it can be used as information to raise awareness of environmental costs.

The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.

1. Solid: A brick is a solid object that maintains a fixed shape and volume.

2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.

3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.

The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.

In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.

Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.

Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.

Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.

Thus, Solid: An object that keeps a constant shape and volume is a brick.

In an analogy of a circuit with a resistance to an obstacle race, we can consider various elements of the race as representative of different components of the circuit.Obstacles, Track or Route, Participants, Start and Finish Line.

Obstacles: The obstacles in the race represent the resistors in a circuit. Just as resistors impede the flow of current in a circuit, obstacles in the race create hurdles that slow down the participants. The difficulty or magnitude of the obstacles can be equated to the resistance value of the resistors in a circuit.

Track or Route: The race track or route itself can be seen as the conductive path in a circuit. It provides a pathway for the participants to move and complete the race. Similarly, the conductive path in a circuit allows the flow of current from the power source to the load.

Participants: The people participating in the race represent the flow of electrons in a circuit. Just as the participants move through the obstacles in the race, electrons move through the resistors in a circuit. The rate at which participants complete the race can be compared to the current flowing through the circuit.

Start and Finish Line: The start and finish line of the race correspond to the terminals of a circuit. The start line represents the positive terminal, where the participants begin their journey, and the finish line represents the negative terminal, where the race concludes.

Answer: As an analogy of a circuit with resistance, the obstacles in an obstacle race represent the resistance in a circuit. The parts of the circuit that the obstacles represent are the resistors. The people in the obstacle race represent the current in a circuit. The current is the flow of charged particles (such as electrons) in a circuit. In an obstacle race, the people are moving through the obstacles, just as the charged particles are moving through the resistors in a circuit. The obstacles slow down the people, just as the resistors slow down the flow of charged particles in a circuit.

Electromagnetic and mechanical waves used when people communicate with each other, this done by an antenna(sender & receiver)

An antenna is a metallic structure that produce or/and receives electromagnetic waves it is available in different shapes. There are different types of antennas which are  Short Dipole antenna, Dipole antenna, Loop antenna, Monopole antenna.

when input of the Dipole antenna is connected to the electric signals having certain frequency. Due to change in the electric signal, there is fluctuation in polarity of dipoles in dipole antenna and that change in the dipole produces electromagnetic wave.

when electromagnetic wave is received by the dipole antenna, dipoles in the antenna get affected by electromagnetic waves, dipoles fluctuate at frequency of received electric signals and produces electric signals of same frequency as electromagnetic wave.

Sound wave is mechanical wave. sound wave is converted in electric signals by using microphone, it gets amplified and given to to input of the antenna(Transmitter).  This antenna converts Electric signal into electromagnetic wave. This converted electromagnetic wave is received by another antenna(receiver). this antenna converts electromagnetic wave into electric signals, this signals are amplified and given it to the speaker.

Hence this is how people use electromagnetic and mechanical waves for communication.

Answer:

v = sqrt((10/7)gh)

Explanation:

The given equation is:

mgh = (1/2)mv^2 + (1/5)mv^2

To solve for v, we can start by simplifying the right side of the equation:

mgh = (7/10)mv^2

Dividing both sides by (7/10)mv^2, we get:

mgh / (7/10)mv^2 = 1

Multiplying both sides by (10/7)m/gh, we get:

v^2 = (10/7)gh

Taking the square root of both sides, we get:

v = sqrt((10/7)gh)

Therefore, the solution for v in terms of m, g, h is:

v = sqrt((10/7)gh)

The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.

Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,

Using Formula:

K.E=\(1/2mv^{2}\)

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.125)(4)^{2}\)

K.E=\(1/2(0.125)(16)\)

K.E=1/2(2)

K.E=1

When the mass of the bottle is 0.250 kg, the Kinetic Energy  is

K.E=\(1/2(0.250)(4)^{2}\)

K.E=1/2(0.125)(16)

K.E=1/2(4)

K.E=2

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.375)(4)^{2}\)

K.E=1/2(0.375)(16)

K.E=1/2(6)

K.E=3

When the mass of the bottle is 0.500 kg, the Kinetic Energy  is

K.E=\(1/2(0.500)(4)^{2}\)

K.E=1/2(0.500)(16)

K.E=1/2(8)

K.E=4

Now we can calculate the change in kinetic energy (ΔKE):

ΔKE = KE(final) - KE(initial)

= 4 kg m*2/s*2 - 1 kg m*2/s*2

= 3 kg m*2/s*2
