It takes 120 minutes for a man to ride his bicycle up the road to Alpe d'Huez in France. The vertical height of the climb is 1,1
Greeley [361]
First solve the potential energy of the biker. using the fomula:
PE = mgh
where m  is the mass of the object
g is the acceleration due to gravity ( 9.81 m/s2)
h is the height

PE = 96 kg ( 1120 m ) ( 9.81 m/s2)
PE = 1054771.2 J
then power = Work / time
P = 1054771.2 J / ( 120 min ) ( 60 s / 1 min)
P = 146.5 W

Which sequence shpes the steps of the proces of science in an order in which they might occur?
ivanzaharov [21]

The steps of the process of science in an order in which they might occur

exploration >> hypothesis >> prediction >> experiment.

The correct option is D.

<h3>Explanation:</h3>
  • A series of sequential steps are included in the scientific method, which is how knowledge in the scientific field is acquired.
  • When a question arises from observing the natural world, a hypothesis is a predetermined explanation of the question.
  • Experimental and/or observational procedures must be used to test a hypothesis and determine whether it is true or false.
<h3>What are some fundamental scientific procedures?</h3>

When scientists conduct research and study, they use specific science process skills. The thinking processes that scientists, teachers, and students use when conducting science include observing, categorizing, communicating, measuring, inferring, and predicting.

The tensile stress in a thick copper bar is 99.5 % of its elastic breaking point of 13.0× 10¹⁰ N/m² . If a 500-Hz sound wave is
dimaraw [331]

The speed of the wave in the rod is

The speed of the wave in the rod is $v = \sqrt{\frac{Y}{\rho}} = \sqrt{\frac{20\times 10^{10}\ \mathrm{N/m^2}}{7.86\times 10^3\ \mathrm{kg/m^3}}} = 5044\ \mathrm{m/s}$

5044m/s

<h3>What is sound wave?</h3>

A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid substance). Pressure waves are produced when an item vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disrupt the particles next to them, and so on. Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
