Find the x-components of this vector: 92.5 m, 32.0 degrees. Remember, angles are measured from the +x axis.
Brrunno [24]

Answer:78.44\ m

Explanation:

Given

magnitude of vector =92.5\ m

vector makes an angle of \theta =32^{\circ} with x-axis

Vector can be resolved into two components i.e. vertical and horizontal

Horizontal component along x-axis=92.5\cos 32

=78.44\ m

along the negative x-axis

in a circuit with two resistors in parallel, which of the following pair applies? a. V and I both increase across both resistors
makvit [3.9K]

The wording of the choices is really unclear.  With two resistors in parallel,
here's the situation:

-- The voltage across each resistor is the same as the voltage across
the other one.  If the parallel combination is connected to the battery,
then the voltage across each resistor is the full battery voltage.

-- The current through each resistor is (V) / (the resistance of that resistor).
That's the same current as would flow through that resistor if the other one
were not there.

-- As long as the battery or other power supply holds out, neither of these
quantities changes.

Can you match this situation to one of the choices listed ?
It looks to me as if choice 'C' is the one that's most likely
trying to say this.

An experiment is designed to see if sleep affects the number of vocabulary words subjects can remember. The dependent variable i
Kaylis [27]

The dependent variable is: <em>"number of vocabulary words subjects can remember"</em>

<h3>Which is the dependent variable?</h3>

In an experiment, we basically see how changing one variable affects another variable.

In this case, the experiment is:

<em>" if sleep affects the number of vocabulary words subjects can remember."</em>

Then the hours of sleep would be the independent variable (the one that the scientist can change) and the number of vocabulary words subjects can remember is the dependent variable (that depends on the independent variable).

So the correct answer is:

<em>"number of vocabulary words subjects can remember"</em>
