How are the 3 steps of scientific inquiry related
DIA [1.3K]
The first three steps in scientific inquiry are related in that they are all equivalent to being on a fact finding mission. The three steps are to find or develop the question that must be answered, to study all related academic literature on the subject, and then to make a guess as to what the answer is.

A laboratory experiment produces a single-slit diffraction pattern on a screen. If the slit is made narrower, the bright fringes
AlekseyPX

Answer:

fringes move farther

Explanation:

The relation between the distance between the fringes is given by

y = Dλ/d

where, D is the distance between the plane of slit and the screen

d is the width of slit, λ is the wavelength of light used.

As the slit made narrower, that means d decreases, the value of y increases, that means the fringes move farther.

A cannon fires a cannonball of mass 16.0 kg by applying a force of 2750 N along the 1.25 m length of the barrel. (a) How much wo
Zarrin [17]

To develop this problem it is necessary to apply the concepts related to Work and energy conservation.

By definition we know that the work done by a particle is subject to the force and distance traveled. That is to say,

W = F*d

Where,

F= Force

d = Distance

On the other hand we know that the potential energy of a body is given based on height and weight, that is

PE = -mgh

The total work done would be given by the conservation and sum of these energies, that is to say

W_{net} = W+PE

PART A) Applying the work formula,

W = F*d\\W = 2750*1.25\\W = 3437.5J

PART B) Applying the height equation and considering that there is an angle in the distance of 25 degrees and the component we are interested in is the vertical, then

PE = -mgh*sin25

PE = -16*9.81*1.15sin25

PE = -82.9J

The net work would then be given by

W_{net} = W+PE

W_{net} = 3437.5J-82.9J

W_{net} = 3354.6J

Therefore the net work done by these 2 forces on the cannonball while it is in the cannon barrel is 3355J
