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.
Answer:
1.0639 A
Explanation:
We have given rms voltage V = 44 volt
Resistance = 60 ohm
According to ohm's law 
So 
this is the rms current but we have to find the maximum current
So maximum current 
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;

Substituting into the formula, we have;

Density = 3 kg/m³
