Complete Question

The complete question is shown on the first uploaded image

Answer:

The expression are

        \Delta E  = \Delta E _1 + \Delta E_2

and

     \Delta E  = \Delta E _3 + \Delta E_4

Step-by-step explanation:

Generally from the diagram  the energy change from state A to  state B is  

        .\  \ \Delta E_2 \ \ \ \ \  \  \ \ \Delta E_2  \\A  \ \ \to \ \ \  C \ \ \ \to \ \ \  B\\

Also  

.\  \ \Delta E_3 \ \ \ \ \  \  \ \ \Delta E_4  \\A  \ \ \to \ \ \  D \ \ \ \to \ \ \  B\\

So  two expressions for the difference in internal energy between state a and state b are  

      \Delta E  = \Delta E _1 + \Delta E_2

and

     \Delta E  = \Delta E _3 + \Delta E_4

In circle O, m∠R = 30.8°. Find m∠NOQ.
nordsb [41]

Given:

In circle O, m∠R = 30.8°.

To find:

The m∠NOQ

Solution:

Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.

Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.

Using central angle theorem, we get

m\angle NOQ=2\times m\angle NRQ

m\angle NOQ=2\times m\angle R

m\angle NOQ=2\times 30.8^\circ

m\angle NOQ=61.6^\circ

Therefore, m\angle NOQ=61.6^\circ.

A golfer hits a ball from a starting elevation of 4 feet with a velocity of 70 feet per second down to a green with an elevation
mafiozo [28]

Answer:

t = 4.5 seconds

Step-by-step explanation:

It is given that, a golfer hits a ball from a starting elevation of 4 feet with a velocity of 70 feet per second down to a green with an elevation of −5 feet.

The number of seconds t it takes the ball to hit the green can be represented by the equation as follows :

-16t^2 + 70t + 4 = -5\\\\-16t^2 + 70t + 9=0......(1)

We need to find time taken by the ball to land on the green. Solving the quadratic equation (1) we get :

t = -0.125 s and t = 4.5 s

Ignoring t = -0.125 s, we get the time taken by the ball to land on the green is 4.5 seconds.

What is the value of the expression
prisoha [69]

Answer:

6

Step-by-step explanation:

Follow the PEMDAS rule.

Parentheses

Exponent

Multiplication

Division

Addition

Subtraction

By following that rule, you know that you have to take care of the exponent first. 1/2 to the fourth power is 1/16. Then the next step in pemdas is to multiply that with 48, which is 3. The you subtract 3 from 9.

Hope this helps <3
