Answer:
As the wavelength of an electromagnetic wave _decrease__ the frequency of the wave _increase_______.
Explanation:
What is the relationship between frequency and wavelength?
Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation that relates wavelength and frequency is:
V= fλ
where v= velocity
f= frequency
λ = wavelength
⇒ f = v/λ
also f ∝ 1/λ
For electromagnetic radiation, the speed is equal to the speed of light, c, and the equation becomes:
C= fλ
where c= Speed of light
f= frequency
λ = wavelength
⇒ f = v/λ
also f ∝ 1/λ
Answer:
false, because a phase change occurs physical changes when matter changes its energy state.
Answer:
1654 kg m/s
Explanation:
The impulse experienced by an object is equal to the product between the force exerted on the object and the time during which the force lasts:

where:
I is the impulse
F is the force exerted on the object
is the time during which the force is applied
For the object in this problem, we have
(force applied)
(time interval)
Therefore, the impulse experienced by the object is:

Answer:
349 m
Explanation:
Parameters given:
Mass of climber, m = 92.6 kg
Amount of food calories = 735
1 food calorie = 103 calories
735 food calories = 75705 calories
1 joule is equal to 0.239 calories. Therefore, 75705 calories will be 316749.72 joules.
Hence, this is the amount of work the climber must do work off the food he ate.
Work done is given as:
W = Force * distance
W = m * g * h
h = W/(m * g)
h = 316749.72/(92.6 * 9.8)
h = 349 m
