Why is friction not necessary?
During solving the questions (In Physics) sometimes we consider the bodies frictionless but friction exists. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : sorry mom calling(:P)
A body slides down a frictionless plane and during the third second after starting from rest it travels 19.4m what is the angle of inclination of the plane?
x is distance a is acceleration x = 1/2at2 19.4 = 1/2a32 a = 4.311 m/s2 The acceleration of gravity on the Earth is 9.81 m/s2 If the plane is not inclined then the acceleration is 0%. If the plane is inclined by 90' then the acceleration is 100%. Clearly the applicable trigonometric function is sine. 4.311 = 9.81 sin(angle) angle = 26.069'
What is its average speed during this 11 s interval?
To get average speed, just divide distance by time. In this case, you divide whatever distance an object moves during the 11 seconds, by the 11 seconds.
During a single period the distance traveled by a wave is?
During a single period a wave travels just one wavelength.

When does weightless occur?
During free fall.
Are the gases that humans exhale during respiration weightless?
yes
During the swing of a frictionless pendulum what energy forms remain constant?
The sum of potential + kinetic energy.
Are astronauts weightless in a space shuttle during the launch?
No, quite the opposite. They experience up to three times the normal force of gravity during the launch.

What molecules attached to the tRNAs?
During translation, an amino acid specific to the t-RNA molecule is attached to it.
Was John Glenn the first US person to be weightless?
No, it is possible that earlier pilots experienced weightlessness during parabolic arcs. The first American into space was Alan Shepard.
For what did the astronauts use silly putty?
Silly putty was used by astronauts to fasten down tools during the weightless gravity period and to alleviate boredom.
Where is messenger RNA attached during protein construction?

What is an area where the chromosome are attached?
The chromosomes are attached at their centromeres, which in turn attach to spindle fibers when being pulled apart during mitosis.
