Answer:

For any plane reflector, the angle of reflection is always equal to the angle of incidence.

We know that thelight ray at an angle of 61 degrees from above (i assume that those 61° are between the light ray and the surface of the mirror), so the angle with respect to the normal of the mirror will be the complementary angle A = 90° - 61° = 29°

This means that the incidence angle is equal to 29°, then, the reflection angle is also 29°.

Now, if the initial angle is with respect to the normal of the mirror, the reflection angle is equal to it, so the reflection angle is also 61°

Answer:

The answer is radio waves

In a series circuit represented by Ohm's law, the correct formulas to use are I = I1 = I2 = I3 for region X and Req = R1 + R2 + R3 for region Y, indicating that current remains constant through components and resistances are additive.

Wendy is working with Ohm's law and electric circuits and needs to know which formulas apply to regions marked X and Y in her graphic organizer. Ohm's law describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit and is given by V = IR. When multiple resistors are present in a circuit, their total or equivalent resistance (Req) and the total current depend on whether they are arranged in series or parallel.

In a series circuit, the total current (I) remains the same through all the components, and the voltages across each component add up. Hence, I = I1 = I2 = I3 which would be the correct formula for region X. For region Y, in a series circuit, the equivalent resistance (Req) is simply the sum of all individual resistances, thus Req = R1 + R2 + R3 is the correct formula.

However, in a parallel circuit, the voltage across all components is the same and the currents through each component add up to the total current, which is represented by I = I1 + I2 + I3, but this does not apply to the original question.

The example of figurative language in the phrase "the toast jumped out of the toaster" is a metaphor. Using figurative language in an argument can make it more engaging and persuasive.

The example of figurative language in the phrase "the toast jumped out of the toaster" is a metaphor. A metaphor is a figure of speech that compares two different things by saying one thing is another thing, without using the words "like" or "as". In this case, the toast is compared to something that jumps, which creates a vivid image and adds interest to the description.

The effect of using this metaphor in an argument could be to make the argument more engaging and memorable. By using figurative language, the writer or speaker can convey their message in a more creative and impactful way, capturing the attention of the audience and making the argument more persuasive.

The distance from the center is the lighter child sitting is 1.4 m.

A fundamental characteristic of an object, its inertia is quantified by its mass, which is a basic indicator of the volume of substance inside the thing. Because mass is such a fundamental quantity and is difficult to define in terms of another, definitions of it frequently appear circular.

It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.

Given:

Two children with masses of 22 kg and 40 kg are sitting on a balanced seesaw, the heavier child is sitting 0.7 m,

Calculate the force by both as shown below,

F = 22 × 9.8

F = 215.6

f = 40 × 9.8

f = 392

Calculate the distance as the seesaw is in equilibrium,

196x = 392 × 0.7

x = 274.4 / 196

x = 1.4 m

The relationship between mass and acceleration according to Newton's second law of motion is that acceleration is directly proportional to the net external force and inversely proportional to the mass of the object. So, larger mass leads to smaller acceleration for the same applied force.

According to Newton's second law of motion, the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. This essentially means that the larger the mass of an object, the smaller its acceleration will be when a net external force is applied, due to the object's increased inertia. For example, if you try to push a car and a bicycle with the same amount of force, the car (which has a greater mass) will accelerate slower than the bicycle (which has less mass).

Power plants burn fossil fuels to produce steam, which spins a turbine connected to a generator, converting thermal energy into electrical energy. The electricity is then transmitted and distributed to homes and businesses.

Power plants convert fossil fuels into electrical energy through the following steps:

1. Fuel Combustion: Fossil fuels (coal, natural gas, or oil) are burned in a boiler to produce heat, releasing chemical energy.

2. Heat Production: The heat converts water into high-pressure steam.

3. Steam Generation: The steam heats up and pressurizes.

4. Mechanical Energy: High-pressure steam spins a turbine, converting thermal energy into mechanical energy.

5. Electrical Generation: The turbine drives a generator, converting mechanical energy into electrical energy.

6. Transmission: Electricity is transmitted through power lines at high voltage.

7. Distribution: Substations reduce voltage for safe distribution to homes and businesses.

8. Waste Management: Steam is condensed back to water and reused, and emissions are controlled to minimize environmental impact.

This cycle efficiently converts fossil fuel energy into electrical power.

The answer is solar flare. Solar flares are commonly accompanied by coronal mass ejection. Solar flares are periods when the sun is suddenly brighter at a spot at its surface. This is due to the ejection of electrons, ions, and atoms (plasma clouds) accompanied by electromagnetic waves.

Answer: Solar flare

Explanation:

The electric field does -3.52 times 10⁻¹⁷ joules of work in moving a proton from a potential of +155 V to -65 V.

To calculate the work done by the electric field in moving a proton from a point with a potential of +155 V to a point with a potential of -65 V, you need to use the following formula:

Work (W) = q times triangle V, where q is the charge of the proton and triangle V is the change in electric potential (voltage).

The charge of a proton (q) is 1.60 times 10⁻¹⁹ C. The change in electric potential (triangle V) is the final potential minus the initial potential, which is (-65 V) - (+155 V) = -220 V.

So the work done by the electric field is:

W = (1.60 times 10⁻¹⁹ C) times (-220 V) = -3.52 times 10⁻¹⁷ J.

The negative sign indicates that the work is done by the electric field, not by an external force.

Final answer:

Light scattering caused by the Earth's atmosphere results in the 'twinkling' of stars, polarization of light, and the blue color of the sky. The scattering leads to a blur and changing nature of the blur due to atmospheric conditions. Scattered blue light colors the sky and makes the Sun appear yellower.

Explanation:

When light rays spread out through the Earth's atmosphere, they undergo a process known as scattering. This can be compared to the way confetti is dispersed by the wind. As light from the stars enters our atmosphere, various air currents and atmospheric conditions alter their paths leading to a blurred image when viewed from Earth; this effect is often observed as the twinkling of stars. Interestingly, polarization by scattering also occurs, and the light from the sky can appear brighter or dimmer when viewed through polarized lenses like sunglasses due to this scattering effect.

The blue color of the sky is also a result of scattering. Molecules in the atmosphere scatter shorter wavelengths of light (blue) more than longer wavelengths (red). This preferential scattering causes the sky to appear blue and the sun to seem somewhat yellower than it would in space. Furthermore, the intensity of light diminishes as it travels farther from its source. The light from the sun travels such long distances that by the time it reaches Earth, its rays are essentially parallel, causing consistent scattering across the globe.

Answer:

180

Explanation:

If the work input equals 240 then we follow the equation for work output.

Work output = (work input x efficiency)/100%

Work output = (240 x 75%)/100%

Work output = 180/100%

Work output = 180
