Answer:

Step-by-step explanation:
Given that,
Speed of a toy car, v = 7.2 m/s
Radius of the circular track, v = 1.5 m
We need to find the acceleration of the car. When an object moves in a circular path, it will have centripetal acceleration. It can be given as follows :

So, the centripetal acceleration of the toy car is
. Hence, the correct option is (c).
Here are the steps. I'll try to make them as easy as possible :)
2/3x+1=5
Step 1: Subtract 1 from both sides.
2/x+1-1=5-1
Step 2: Multiply both sides from 3/2
(3/2)*(2/3x)=(3/2)*(4)
And the answer will be 6
x=6
Answer:
Option A, πr^2h
Step-by-step explanation:
V=πr^2h
Answer: Option A, πr^2h
Answer:
The total number of people in the room is: 28 + 21 = 49 (people)
The percentage of women in the room will be: (28 . 100)/49 ≈ 57%
So the proportion of women in relation to the total number of people is:
57/100 = 28/49
