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.
if it takes 1 second to move from x to y. You haven't specified if x and y are extreme point or x is extreme and y is equilibrium point
I.If both are extreme points the period is T=1*2=2s
f(frequency)=2π/T(period)
f=6.28/2=3.14Hz
II.If x is an extreme point and y is equilibrium
T=4*1=4s
f=6.28/4=1.57Hz
Answer:
Well it really depends because he found out about a lot of things in a lot of scientific fields actually. He is known for contributing Pascal's triangle and probability theory. He also invented an early digital calculator and a roulette machine. In the field of physics, Blaise contributed to the study of atmospheric pressure by discovering that vacuums are real and exist in the real world.
<h2>
Power of cheetah is 5576.85 W = 7.48 hp</h2>
Explanation:
Power is the ratio of energy to time.
Here we need to consider kinetic energy,
Mass, m = 102 kg
Initial velocity = 0 m/s
Final velocity = 16.2 m/s
Time, t = 2.4 s
Initial kinetic energy = 0.5 x Mass x Initial velocity² = 0.5 x 102 x 0² = 0 J
Final kinetic energy = 0.5 x Mass x Final velocity² = 0.5 x 102 x 16.2² = 13384.44 J
Change in energy = Final kinetic energy - Initial kinetic energy
Change in energy = 13384.44 - 0
Change in energy = 13384.44 J
Power = 13384.44 ÷ 2.4 = 5576.85 W = 7.48 hp
Power of cheetah is 5576.85 W = 7.48 hp
Catalysts
a catalyst is something added to a reaction that speeds it up (or lowers the activation energy)
increasing the temp would speed up the whole reaction but not lower the activation energy
so B.
