Answer:  

(a) 0.2165 rad/sec

(b) 2.6143 m /sec

(C) 0.459rad/sec^2

Explanation:

It is given that wheel rotates each revolution in 29 sec

So time period T = 29 sec

(a) Angular speed is equal; to \omega =\frac{2\pi }{T}=\frac{2\times 3.14}{29}=0.2165rad/sec

(b) Radius is given r = 12.2 m

So linear velocity v=\omega r=0.2165\times 12.2=2.6143m/sec

(C) Angular acceleration is given by a=\frac{v^2}{r}=\frac{2.6143^2}{12.2}=0.459rad/sec^2

s344n2d4d5 [400]

Answer:

72  is the premimum of the insurance.

Explanation:

Below is the given values:

The loading = 0.4

Coinsurance rate = 0.2

Number of units = 100

Total number of units = 100 * 0.4 = 40

Remaining units = 60 * 0.2 = 12

Add the 60 and 12 values = 60 + 12 = 72

Thus, 72  is the premimum of the insurance.

<h2>If two sets of data are correlated, this means that: one set causes the other to happen. </h2>

Explanation:

Correlation indicates a relationship between two or more variables, but this relationship does not suggest cause and effect. When two sets of data are correlated, it means that as one variable changes, the other variable also changes.

The correlation can be measured by calculating a statistic called as correlation coefficient. The number from -1 to +1 indicates the strength and direction of the relationship between variables. The correlation coefficient is denoted by the letter r.

What does the sun consume to produce energy and helium?
aev [14]
This reaction, known as nuclear fusion, converts hydrogen atoms into helium. The by-product of nuclear fusion in theSun's core is a massive volume ofenergy that gets released and radiates outward toward the surface of the Sunand then into the solar system beyond it.
