Answer:
Perimeter=
Step-by-step explanation:
Given:
length of the rectangle=
Width of the rectangle=
Perimeter of a rectangle= 2(length+width)
Perimeter
So, the expression of the perimeter of given rectangle is:
Given:
radius of the pendulum = 6 feet
arc length = 14.13 feet
time = 3 seconds
Required:
What is the angular velocity?
Solution:
To compute for the angular velocity, we can use the formula:
w = s/rt
where,
w is the angular velocity
s is the length of the arc
r is the radius of a circle or pendulum
t is the time
substituting the values,
w = 14.13 feet / 6 feet × 3 seconds
w = 0.785 per seconds
Answer:
See below ↓↓
Step-by-step explanation:
<u>A to B</u>
- Avg. speed = Distance covered / Time taken
- Avg. speed = 200 m / 10 s
- Avg. speed = <u>20 m/s</u>
<u></u>
<u>C to D</u>
- Avg. speed = Distance covered / Time taken
- Avg. speed = (500 - 200) m / (60 - 30) s
- Avg. speed = 300 m / 30 s
- Avg. speed = <u>10 m/s</u>
