Which motion maps show an object in uniform circular motion? Check all that apply. V W X Y
2 answers:
Explanation:
In this case we need to say that out of the attached figure which shows that the object is in uniform circular motion.
When and object moves in a circular path, its motion is called circular motion. In this type of motion, the speed of the object remains constant while its position changes i.e. its velocity changes.
Out of attached options, V shows circular motion, as the object is position continuously. W and Y are similar cases.
So, V, X and Y shows the circular motion of the object. Hence, this is the required solution.

Answer:
R2 = 300 Ohms
Explanation:
Let the two resistors be R1 and R2 respectively.
RT is the total equivalent resistance.
Given the following data;
R1 = 100 Ohms
RT = 75 Ohms
To find R2;
Mathematically, the total equivalent resistance of resistors connected in parallel is given by the formula;
Substituting into the formula, we have;
Cross-multiplying, we have;
75 * (100 + R2) = 100R2
7500 + 75R2 = 100R2
7500 = 100R2 - 75R2
7500 = 25R2
R2 = 7500/25
R2 = 300 Ohms
