Answer: The answer is "C"
Explanation:
The electromagnetic waves are arranged in the increasing wavelength and energy by the following order;
Radio waves has the lowest energy and wavelength but of the highest frequency.
The Infra-red rays follows the visible light follows, the ultraviolet ray follows, the X-ray follows and then the Gamma-ray has the highest energy and wavelength but the lowest frequency.
Therefore the answer is C, radio, infra, visible, ultraviolet, x-ray, gamma.
Answer:
C
Explanation:
Electromagnetic waves are categorized in terms of their wavelengths and frequency. This categorization is known as the Electromagnetic Spectrum.
When they are arranged in terms of increasing frequency, their wavelengths are decreasing. This is because wavelength and frequency are inversely proportional.
Since energy and frequency are directly proportional, increasing frequency would mean increasing energy.
In terms of increasing energy, the correct order is:
Radio waves
Infrared
Visible light
Ultraviolet
X rays
Gamma rays

D. 80 degrees.
Answers
D. 80 degrees.
The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.

Final answer:
Without seeing the specific waveforms for Wave A and Wave B, we cannot draw a conclusive comparison. However, comparing waveforms can give insights into aspects such as frequency, wavelength, amplitude, and phase difference.
Explanation:
Without the actual illustrations of waveforms for Wave A and Wave B, it's not possible to draw a reliable conclusion about these waves. However, generally, by comparing waveforms, we can discern their frequency, wavelength, amplitude, and phase difference. For example, if Wave A has more complete cycles passing a certain point in a given time than Wave B, we can conclude that Wave A has a higher frequency. If wave A has a higher peak than Wave B, we can say that Wave A has a greater amplitude. These are examples of the types of conclusions one could potentially draw from waveforms, but without the specific waveforms for Wave A and Wave B, any conclusion here would be purely hypothetical.

Answer: 54 miles in 1hr 30min
Explanation:
The train travels at a constant speed of 36 miles per hour. To find out how far it can travel in 1 hour 30 minutes, we need to convert the time to hours. Since there are 60 minutes in 1 hour, 1 hour 30 minutes is equal to 1.5 hours (1 hour + 30 minutes/60 minutes). To calculate the distance traveled, we multiply the speed of the train (36 miles per hour) by the time it travels (1.5 hours). So, the train can travel 36 miles per hour * 1.5 hours = 54 miles in 1 hour 30 minutes. Therefore, the train can travel a distance of 54 miles in 1 hour 30 minutes

Answer:
188.7 m
Explanation:
height of bridge above water (h) = 393 m
mass of bungee jumper (m) = 150 kg
length of cord (L) = 78 m
acceleration due to gravity (g) = 9.8 m/s
initial energy = mgh = 150 x 9.8 x 393 = 577,710 J
since the jumper barely touches the water, the maximum extension of the cord (x) = 393 - 78 = 315 m
from the conservation of energy mgh =
therefore
577,710 =
k = 11.64 N/m
from Hooke's law, force (f) = kx' ⇒ mg = kx'
where x' is the extension of the cord when it comes to rest
150 x 9.8 = 11.64 × x'
x' = 126.3 m
the final height at which the cord comes to a rest = height of the bridge - length of the cord - extension of the cord when it comes to rest
the final height at which the cord comes to a rest = 393 - 78 - 126.3 = 188.7 m

Answer:
F = 231.77N
Explanation:
Given the following data
Distance of Hunter's shoulder (d) = 3.16cm = 0.0316m
mass of bullet (m1) = 0.0137 kg
velocity of bullet (v1) = 546 m/s
mass of rifle(m2)= 3.82 kg
Velocity of rifle (V2) = 1.958167539 m/s
Momentum = MV
Momentum is conserved
Since we are looking for the force exerted on the shoulder by the rifle
Work done = Force × distance (F×d)
The rifle possessed kinetic energy = 1/2mV²
Therefore, work done = kinetic energy
F×d = 1/2mv²
F = 0.5mv²/d
By substitution we have
F = 0.5×3.82×1.9582²/0.0316
F = 7.324/0.0316
F = 231.77N

Explanation:
The power required to lift a weight depends on the force needed and the speed at which the weight is lifted. The force required to lift a weight is given by the equation F = m * g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.81 m/s² on Earth).
For example, if a 1000 kg weight is lifted 10 m in 10 seconds, the work done can be calculated as W = (1000 kg) * (9.81 m/s²) * (10 m) = 98100 J (Joules). The power required is work done per unit time P = (98100 J) / (10 s) = 9810 W (Watts), which is approximately 9.8 kW¹.
In terms of horsepower, since 1 horsepower is approximately equal to 746 Watts¹, the power required would be about 13.15 horsepower. So, it does not require 100 horsepower to lift a 1000 kg weight from the ground under these conditions. However, these calculations assume ideal conditions and do not take into account factors such as air resistance or mechanical inefficiencies. In real-world applications, more power might be needed.
