What is the angular velocity of a 6–foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for π.

Mila [183]

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

For the point P(6,8) and Q(11,11), find the distance d(P,Q) and the coordinates of the

devlian [24]

Answer:

The distance of PQ = $\sqrt{34}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the points are P(6,8) and Q(11,11)

Distance formula

PQ = $\sqrt{x_{2}-x_{1} )^{2} +(y_{2} - y_{1})^{2} }$

= $\sqrt{11-6)^{2} +(11-8)^{2} }$

= $\sqrt{(5)^{2}+(3)^{2}} }$

= $\sqrt{25+9}$

= $\sqrt{34}$

In Bluepoint, the average low temperature for January was 40 °F. The average low in February was 27% lower. What was the average

yarga [219]

The average low temperature for January was 40 °F - 100%.

The average low in February was x °F - 27% lower, that is 100%-27%=73%.

Write a proportion:

$\dfrac{40}{x}=\dfrac{100}{73},\\ \\x=\dfrac{73\cdot 40}{100},\\\\x=29.2$

Answer: the average low in February was 29.2 °F.
