Answer to Problem 1RQ

Option (e)

Explanation of Solution

Wavelength of light could be much shorter or much longer than a human eye can detect. Light are called electromagnetic waves because it is related to both electricity and magnetism. The range of different wavelengths of light called as electromagnetic spectrum.

The electromagnetic spectrum is divided into seven regions in order of increasing frequencies they are as follows:

Radio waves

Microwaves

Infrared

Visible light

Ultraviolet (UV)

X-rays

Gamma rays

The diagram representing the frequency is given below.

    In Quest Of The Universe, Chapter 4, Problem 1RQ

Conclusion:

The frequency of visible light falls between ultraviolet and radio waves. Thus, option (e) is correct.

Infrared waves and radio waves both are on right side of visible region. Thus, option (a) is incorrect.

X- Rays and cosmic rays both falls on left side of visible region. Thus, option (b) is incorrect.

Ultraviolet waves and X rays both lie on the same side of visible region. Thus, option (c) is incorrect.

Short radio waves and long radio waves both are types of radio waves. Thus, option (d) is incorrect.

Need help on the following questions on biomechanics. (Please refer to images below)A gymnast weighing 68 kg attempts a handstand using only one arm. He plants his handat an angle resulting in the reaction force shown.A) Find the resultant force (acting on the Center of Mass)B) Find the resultant moment (acting on the Center of Mass)C) Draw the resultant force and moment about the center of mass on the figure below. Will the gymnast rotate, translate, or both? And in which direction?
Please help me on the following question (Please refer to image below)An Olympic lifter (m = 103kg) is holding a lift with a mass of 350 kg. The barexerts a purely vertical force that is equally distributed between both hands. Each arm has amass of 9 kg, are 0.8m long and form a 40° angle with the horizontal. The CoM for each armis 0.5 m from hand. Assuming the lifter is facing us in the diagram below, his right deltoidinserts 14cm from the shoulder at an angle of 13° counter-clockwise from the humerus.A) You are interested in calculating the force in the right deltoid. Draw a free body diagramof the right arm including the external forces, joint reaction forces, a coordinate system andstate your assumptions.B) Find the force exerted by the right deltoidC) Find the shoulder joint contact force. Report your answer using the magnitude and directionof the shoulder force vector.
