Un tren va a una velocidad de 18m/s frena y se detiene en 15s calcula su aceleracion y la distancia recorrida al frenar

Answers

Answer:

Acceleration is -1.2 m/s² and distance covered is 135 m.

Explanation:

A train going at a speed of 18m / s brakes and stops in 15s calculates its acceleration and the distance traveled when braking

Given that,

The initial speed of the train, u = 18 m/s

Final speed, v = 0

Time, t = 15 s

We need to find acceleration and distance traveled when braking. Let a is acceleration and distance traveled.

Acceleration,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0-18}{15}\\\\a=-1.2\ m/s^2[/tex]

Using third equation of motion,

[tex]v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{0^2-18^2}{2\times (-1.2)}\\\\d=135\ m[/tex]

Hence, acceleration is -1.2 m/s² and distance covered is 135 m.

Answers

Answer:

Converted to an amount of energy equal to 4 million tons times the speed of light squared. ejected into space in a solar wind.

Explanation:

The 4 million tons of mass is converted to the amount of energy that is equal to 4 million tons times the speed of light squared. This energy moves from the sun with the help of solar winds and received by the planets present in the solar system. This solar energy moves in the form of solar radiation because there is no medium for propagation so that's why we can say that the mass is converted into energy that moves in the form of radiation in discrete packets.

How did we see through Venus thick atmosphere?

Answers

Answer:

The Venusian atmosphere supports opaque clouds of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging. Aside from carbon dioxide, the other main component is nitrogen

Explanation:

Because Venus has such a dense atmosphere which is some 100 times thicker than the earth's. Evidently, Venus is sufficiently close to the Sun that the little carbon dioxide it had in its early, Earth-like atmosphere caused the surface to warm up and leach out more carbon dioxide into the atmosphere.

What is the potential difference across a circuit that delivers 4.2A to a 500W motor?

Answers

Answer:

Thus, the potential difference is 119 V.

Explanation:

Current, I = 4.2 A

Power, P = 500 W

The rate of doing work is called power.

The SI unit of power is Watt.

The  commercial unit of power is horse power.

1 horse power = 746 Watt

The formula of the electrical power is

P = V I

where, V is the voltage and I is the current.

Substitute the values in the formula

500 = 4.2 x V

V = 119 V

According to the special theory of relativity, what is the fourth dimension?

Answers

Explanation:

A four-dimensional space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible abstraction of the observation that one only needs three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

According to the special theory of relativity, the fourth dimension is time. The special theory of relativity, proposed by Albert Einstein in 1905, revolutionized our understanding of space and time.

It states that space and time are interconnected and form a four-dimensional framework known as spacetime. In this framework, three dimensions correspond to space (length, width, and height), and the fourth dimension is time. Einstein's theory introduced the concept of time dilation, which means that time can appear to pass differently for observers in relative motion. This idea challenges the notion of time as an absolute quantity and demonstrates that it is influenced by an observer's relative motion and gravitational fields.

To visualize the fourth dimension, consider a space-time diagram where an object's position in space is plotted against time. Each point on the diagram represents an event, combining its spatial coordinates with the time at which it occurred. This four-dimensional representation allows us to understand the relationship between space and time in a unified framework.

A parallel plate capacitor of capacitance Co has plates of area A with separation d between them. When it is connected to a battery of voltage Vo, it has charge of magnitude Qo on its plates. It is then disconnected from the battery and the plates are pulled apart to a separation 2d without discharging them. After the plates are 2d apart, the new capacitance and the potential difference between the plates are: (Show all steps) [2 marks] a. ½ Co, ½ Vo b. ½ Co, 2Vo c. Co, Vo d. Co, 2Vo e. 2Co, 2Vo

Answers

Answer:

b. 1/2·C₀, 2·V₀

Explanation:

The capacitance on the parallel plate capacitor = C₀

The area of the plates  = A

The voltage on the battery = V₀

The magnitude of the charge on the plate = Q₀

The new distance between the plates = 2·d

From an online physics source, we have;

[tex]C_0 = \epsilon_0 \times \dfrac{A}{d}[/tex]

Where;

ε₀ = Constant

A = The area of the plates

With the new distance, 2·d, we get;

[tex]C_{new} = \epsilon_0 \times \dfrac{A}{2\cdot d} = \dfrac{1}{2} \times \epsilon_0 \times \dfrac{A}{d} = \dfrac{1}{2} \times C_0[/tex]

Therefore;

[tex]The \ new \ capacitance \ C_{new} = \dfrac{1}{2} \times C_0[/tex]

The potential difference, 'V', is given as follows;

[tex]C = \dfrac{Q}{V}[/tex]

Therefore;

[tex]V = \dfrac{Q}{C}[/tex]

Given that Q = Q₀, we get;

[tex]V = \dfrac{Q_0}{\dfrac{1}{2} \times C_0} = 2 \times \dfrac{Q_0}{C_0} = 2 \times V_0[/tex]

∴ V = 2 × V₀

The new potential difference, V = 2·V₀

Therefore, after the plates are 2·d apart, the new capacitance and potential difference between the plates are;

1/2·C₀, 2·V₀.

At a distance of 2d, the potential difference will be twice the potential difference before while the capacitance will be half the value before.

Given to us

The capacitance on the parallel plate capacitor = C₀The area of the plate = AThe voltage on the battery = V₀The magnitude of the charge in the plate = Q₀The new distance between the plates = 2d

What is Capacitance?

We know capacitance can be written as,

[tex]C= \dfrac{\epsilon_0 A}{d}[/tex]

where C is the capacitance,

A is the area,

d is the distance and

ε₀ is the electrostatic constant,

Capacitance before,

[tex]C= \dfrac{\epsilon_0 A}{d}[/tex]

Capacitance Afterwards,

[tex]C= \dfrac{\epsilon_0 A}{2d}[/tex]

[tex]C=\dfrac{1}{2} \times \dfrac{\epsilon_0 A}{d}[/tex]

[tex]C=\dfrac{1}{2} \times C_0[/tex]

What is Voltage(Potential difference)?

We know that  for the voltage we can write,

[tex]\rm Voltage = \dfrac{Charge}{Capacitance}[/tex]

Voltage before

[tex]V=\dfrac{Q_0}{C_0}[/tex]

Voltage Afterwards

[tex]V_{new} = \dfrac{Q_0}{C_{new}}[/tex]

[tex]V_{new} = \dfrac{Q_0}{\dfrac{1}{2} \times C_0}[/tex]

[tex]V_{new} = 2 \times\dfrac{Q_0}{C_0}[/tex]

[tex]V_{new} = 2 \times V_0[/tex]

Hence, At a distance of 2d, the potential difference will be twice the potential difference before while the capacitance will be half the value before.

How does the circuit structure affect the brightness of a bulb? How does the circuit structure affect the energy required to keep bulbs lit? Summarize some of the tradeoffs (pros and cons) of wiring bulbs in series vs. Parallel.

Answers

Answer:

Part A

The relationship between the circuit structure and the brightness of the bulb are;

The brightness of the bulb depends on the voltage to which the bulb is connected to

Bulbs connected in parallel, are connected directly to the voltage of the power source and are therefore brighter than bulbs arranged in series due to the reduced potential difference between bulbs in series and the voltage source

Part B

Given that bulbs are brighter when arranged in parallel, they require more energy to keep the bulbs lit than when they are arranged in series

Part C

The pros and cons of wiring bulbs in series and parallel are;

Series Circuits Disadvantage

i) A failure of one bulb arranged in series can lead to a failure of the circuit

ii) Bulbs arranged in series are not as bright as bulbs arranged in parallel

iii) When the number of bulbs arranged in a series are increased, the brightness decreases

iv) The bulbs cannot be controlled independently

Advantages of Series Circuits

i) Series circuits consume less energy and the batteries last longer when the attached bulbs are arranged in series

Disadvantage of bulbs arranged in parallel

i) The battery power quickly consumed

The Advantages of Bulbs in Parallel

i) The bulbs light brighter when they are in parallel

ii) The bulbs can be individually controlled

iii) The current can flow through more than one path way

iv) When one bulb fuses, the others in the circuit keep working
