the graph below shows the motion of an object over a certain period of time. various intervals of time are depicted by letters.

MA_775_DIABLO [31]

Answer:

Options (C) and (F).

Explanation:

Constant speed of an object is represented by the flat segment (a line parallel to the x-axis) on the graph of velocity and time.

In other words, flat segments represents no change in the velocity with respect to the time.

From the graph attached,

Being flat segments, C and F will represent the constant speed.

Therefore, Options (C) and (F) will be the correct options.

An AC generator supplies 44 rms volts to a 60-Ω resistor at 60 Hz. What is the maximum current in the resistor?

Brilliant_brown [7]

Answer:

1.0639 A

Explanation:

We have given rms voltage V = 44 volt

Resistance = 60 ohm

According to ohm's law $V=iR$

So $44=i\times 60$

$i=\frac{44}{60}=0.7333A$ this is the rms current but we have to find the maximum current

So maximum current $i_m=\sqrt{2}i_{rms}=1.414\times 0.7333=1.03693A$

What is the density of a substance of volume 3 m3and mass 9 kg?

butalik [34]

Answer:

Density = 3 kg/m³

Explanation:

Given the following data;

Volume = 3m³

Mass = 9 kg

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

$Density = \frac{mass}{volume}$

Substituting into the formula, we have;

$Density = \frac{9}{3}$

Density = 3 kg/m³
