Fernanda is working on a physics project. she is experimenting by rolling a marble down a ramp and then seeing how far it rolls

along the floor after leaving the ramp. which would be the dependent variable in fernanda’s experiments? the angle of the ramp the length of the ramp the distance the marble rolls after the ramp the direction that gravity makes the marble roll

The distance covered on the floor after leaving the ramp is the dependent variable.

  • As a result of the marble's size, the substance it is constructed of, and the angle at which it is placed onto the ground, the distance it rolls varies.
  • Therefore, the angle at which the marble is released onto the ground, the type of material used to make the stone, or its size can all be considered independent variables.
<h3>What is Independent variable?</h3>
  • There are independent and dependent variables in every experiment.
  • A variable is considered independent if its change is not influenced by the change in another variable or factor.
<h3>What is Dependent variable?</h3>

In any experiment, the dependent variable must be measured or determined, and it must change as the independent variable does.

A 208-volt, 4-wire, 3-phase wye power system feeds a school building. Daily voltage readings taken for 1 week are 205.25 volts,
joja [24]

For a 208-volt, 4-wire, 3-phase wye power system feeds a school building, the average daily voltage is mathematically given as

x=206.23v

<h3> What is the average daily voltage of the system?</h3>

Generally, the equation for the mean  is mathematically given as

x=total sum/ number

Therefore

ts=05.25 volts, 203.75 volts, 208 volts, 204.35 volts, 206.7 volts, 207 volts, and 208.55 volts.

ts=1433.6

In conclusion

x=1433.6/7

x=206.23v

An airplane flying parallel to the ground undergoes two consecutive displacements. The first is 76 km at 39.8◦ west of north, an
sweet [91]

Answer:

  162 km

Explanation:

A diagram can be helpful.

Using the law of cosines, we can find the magnitude of the distance (c) to satisfy ...

  c^2 = a^2 +b^2 -2ab·cos(C)

where C is the internal angle of the triangle of vectors and resultant. Its value is ...

  180° -39.8° -59.9° = 80.3°

Filling in a=76 and b=156, we get ...

  c^2 = 76^2 +156^2 -2·76·156·cos(80.3°) ≈ 26116.78

  c ≈ √26116.78 ≈ 161.607

The magnitude of the total displacement is about 162 km.

_____

Please note that in the attached diagram North is to the right and East is up. That alteration of directions does not change the angles or the magnitude of the result.
