Answer:
High Amplitude
Explanation:
If the light from Star X is brighter than the same type of light from Star Y, you know that the light you see from Star X has a higher amplitude.
Denise wears an extremely bright safety yellow sweatshirt when she cycles to the gym after dark. The sweatshirt's brightness reflects the high amplitude of the light it reflects.
The brightness of Denise's sweatshirt while cycling after dark reflects the intensity of light it reflects. The color yellow is perceived when an object reflects red and green light and absorbs blue light. The brightness can also be enhanced by the reflection efficiency of the sweatshirt's material and its fluorescence properties.
Denise's extremely bright safety yellow sweatshirt when she cycles to the gym after dark, reflects the intensity of the light it reflects. The color of an object is determined by the wavelengths of light that the object reflects. A yellow object appears yellow because it reflects yellow light and absorbs other colors. Reflection of light is the fundamental concept behind the brightness of the sweatshirt.
The yellow sweatshirt absorbs blue light and reflects red and green light, which our eyes perceive as yellow. The intensity or brightness of the sweatshirt is a function of how much light it reflects back. Another important factor is the reflection efficiency of the sweatshirt's material. Some materials are better at reflecting light than others which can enhance brightness.
Also, the fluorescence property of some safety colors makes them emit more light than they receive which enhances their brightness, this is especially useful in low light conditions, such as cycling after dark.

b. False
Answer: The given statement is true.
Transport of oxygen from the air takes place through respiratory system. Oxygen from air ( that is taken from the atmosphere) enters via a system of tubes, into our lungs and then it is released into the bloodstream ( to serve in various organs) whereas opposite route is followed by CO2 ( carbon dioxide).
In the respiratory tract, the nose is lined by mucosal epithelium that possessed glands ( which secrete thick mucus). Due to this, air is moistened. Beneath the epithelium surface, there lies network of blood vessels that help in warming the nasal cavity and thus the air is warmed.

The question involves a block sliding down a 30-degree incline, where the forces of gravity, normal force, and friction are in effect. The acceleration of the block can be determined by taking into account all the forces acting on it. This is a topic in Physics, typically studied at the high school level.
In the described scenario, a block is sliding down a rough ramp inclined at 30 degrees. This topic falls under the area of Physics, specifically in the study of friction and forces. The forces at play in this situation are gravity, normal force, and frictional force. When a block slides down an inclined plane, the force of gravity is divided into two components. The component parallel to the ramp, mg sin θ, acts downwards and is opposed by the force of friction.
The frictional force is determined by multiplying the normal force by the coefficient of friction (μ). This could be represented as F = μN, where F is the frictional slide and N is the normal force. The block's acceleration depends on the net force acting on it, considering all the forces at play.
In this particular situation, where there's a known coefficient of friction of 0.20 and given gravitational and normal forces are 40 N, you can use these values, along with the angle of the ramp, to find the acceleration of the block using formulae from physics.

A block sliding down a rough incline experiences forces from gravity, friction, and normal force. Friction opposes the motion, reducing the acceleration the block would have on a frictionless slope. The acceleration can be calculated from the incline angle and friction coefficient.
The question deals with the physics of a block sliding down a rough, incline plane. When a block is sliding down an inclined plane, there are several forces at play. The gravitational force pulls the block downwards, the normal force counters this directly perpendicular to the slope, and friction acts to oppose the motion of the block. The coefficient of friction between the block and the incline plays a crucial role in the block's acceleration down the incline.
The acceleration of the block can be calculated using the formula a = g sin θ, where g is acceleration due to gravity and θ is the incline angle. However, this applies when there's negligible friction. If friction is involved, it reduces the acceleration from this value. The acceleration on an incline where there is friction can be calculated with the equation ax = g sin θ - μk g cos θ, where μk is the coefficient of kinetic friction.
Using the equation above, you can calculate acceleration if you are given the friction coefficient and the incline's angle. However, if you're given the acceleration and either the incline angle or friction coefficient, you can rearrange the equation to calculate the missing variable, helping you gain more understanding about the impacts of the slope and friction.
