If a force does not act parallel to the resulting displacement, what is the effect on the work done by the force?

Then only the component of the force that's parallel to the displacement
is used to calculate the work.  The component of force that's perpendicular
to the displacement  doesn't move through any distance at all, so its contribution
to the total work is zero.

Suppose that the model presented by student 1 is correct. Based on the information provided, what would be the bond angle in a m
Ugo [173]

Question: Predicting the shape of a molecule is relatively straight forward. A molecule's shape will always be determined by the number of electron pairs around the central atom. The number of electron pair corresponds to the number of atoms that are bound to the central atom of the molecule. For example, water contains two hydrogen atom bound to one atom of oxygen, giving the molecule a linear geometry.

Suppose that the model presented by student 1 is correct. Based on the information provided, what would be the bond angle in a molecule of perchlorate ion.

Answer: Suppose that the model presented by student 1 is correct The (perchlorate ion) will be a tetrahedral shape, O-Cl-O bond angle 109.5 due to four groups of bonding electrons and no lone pairs of electrons.

A boxer punches a sheet of paper in mid air, and brings it from rest up to a speed of 25 m/s in 0.05 s. if the mass of the paper
zepelin [54]
Ok, so you've got to figure out a force F and you have the speed in which the boxer punches on determinate time and the mass of the sheet of paper.

So based on the formula that says that the Force is equal to the mass multiplied by the acceleration => F=ma.
You look at it and see that you only have mass which is measured on KG so there is no problem.
then you have the acceleration which is measured on meters and is defined by: a = Δv/Δt 
So now you can replace the velocity and the time you have there
⇒ a 25m/s / 0.05s 
you have computing that ⇒ 50m because the seconds were cancelled out.
and then you plug the meters into the force equation.
F=(0.005kg)(50)
F=0.25N
so the boxer will have a force of 0.25 Newton's.

A main difference between asteroids and comets is that asteroids are mostly made of rock and comets are mostly made of metals ca
avanturin [10]

We can confirm that the difference between a comet and an asteroid lies in their compositions and physical characteristics <u>derived from those compositions</u>.

As stated in the question, the main difference between an asteroid and a comet is their compositions, meaning the materials from which they form.

Asteroids are rocky objects which a heavy metal composition, while comets tend to be made of dust, ice, and <em><u>some </u></em>rocky material. Some extra differences include:

  • Comets reflect a steady amount of light (because of their ice composition)
  • Asteroids will <em><u>reflect light at random intervals due to some metals that may be present on their surface</u></em>
  • Comets tend to have a tail made of water from the melting ice when reflecting sunlight.

Therefore, we can confirm that the main difference between asteroids and comets is their compositions, which lead to distinct physical characteristics.
