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

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.

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.

C. Sturdy stems

Explanation:

Sturdy stems is the adaptation that enables water hyacinth to get nutrients directly from the water because there is no roots are present for the absorption of nutrients from water. The hollow bulbous stem below each leaf of water hyacinth allows the plant to get nutrients from the water. This hollow bulbous stem allow the plants to float on the water surface, keeping the leaves and flowers above the water so they don't rot.

Answer:

The velocity ratio of the wedge is 0.15

Explanation:

Use the following formula to calculate the velocity ratio

Velocity Ratio = Distance Moved by effort / Distance moved by Load

Where

Distance Moved by effort = 3cm

Distance moved by Load = 20 cm

Placing values in the formula

Velocity Ratio = 3cm / 20 cm

Velocity Ratio = 0.15

B. An echo

Explanation:

An echo is the sound heard after the reflection of sound waves from a hard surface. It has both advantages and disadvantages with respect to its applications.

Some of it applications include;

i. it can be used to determine the depth of the sea

ii. it can be used in crude oil exploration

iii. it can be used to determine the speed of sound in air

An echo is different to reverberation of sound.

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.

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

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.

Answer:

The reaction absorbs energy from its surroundings.

Explanation:

An endothermic reaction is any reaction in which energy is absorbed by the reaction system.Thus implies that energy is withdrawn from the environment A cold pack's function is based on an endothermic chemical reaction.

The absorption of energy by the reaction system means that the environment feels cool in an endothermic reaction.This manifests in a decrease in the temperature of the cold pack.

The gravitational force on the moon is less than on Earth, because the strength of gravity is determined by an objects' mass. The bigger the object, the bigger the gravitational force. Gravity is pretty much everywhere

Explanation:

Why might astronauts choose to “lope” or hop rather than walking or running on the moon? Astronauts can “lope” in the moon's low gravity levels, even though this gait pattern is very difficult to use on Earth.
