First law of thermodynamics is based on conservation of energy that states that energy can never be destroyed, it changes from one form to other form of energy. As in the given image, boiler gives thermal energy in the form of steam and this thermal energy do work on turbine by rotating it.

Second law of thermodynamics states that heat energy always moves from high temperature region to low temperature region until no external energy is given. As in the given image, boiler have high temperature steam and turbine is low temperature region. Therefore, high temperature stream moves from lower area to the turbine.

Hence correct answer -

First law: Thermal energy is used to do work on the turbines.

Second law: High-temperature steam flows to an area of lower temperatures in the turbines.

A box of spherical jawbreaker candies is 23 g and its volume is 32.3 cm3. If the average mass of a single jawbreaker is 0.94 g,
Alex777 [14]

The radius of each jawbreaker is approximately 0.68 cm.

<h3>Volume of a sphere;</h3>
  • v = 4 /3 πr³

where

r = radius

Therefore,

23 g  = 32.3 cm³

0.94 g  = ?

cross multiply

volume of a single jawbreaker = 32.3 × 0.94 / 23 = 30.362 / 23 = 1.32 cm³

Therefore,

volume of each jawbreaker = 4 /3 πr³

1.32 = 4 / 3 × 3.14 × r³

r³ = 1.32 /4.18666666667

r³ = 0.31533683707

r = ∛0.31533683707

r = 0.680651651 = 0.68

Therefore, the radius of each jawbreaker is approximately 0.68 cm.

Consider a collection of charges in a given region and suppose all other charges are distant and have a negligible effect. Furth
AlladinOne [14]

Answer:

E. Some charges in the region are positive, and some are negative.

Explanation:

Electric potential is given as;

V = \frac{W}{Q}

where;

W is the work done in moving a charge between two points which have a difference in potential

Q is quantity of charge in the given region

If the electric potential at a given point in the region is zero, then sum of the charges in the given region must be equal to zero. For the charges to sum to zero, some will be positive while some will be negative,.

Therefore, the correct statement in the given options is "E"

E. Some charges in the region are positive, and some are negative.

What is the lewis dot structure of Na+
SpyIntel [72]
The dots in the Lewis dot structure symbolize an atom's elements. 
<span>Since Na^+ is a positive ion (cation) with a charge of +1, it indicates that it has lost an electron. </span>
<span>Since Na had one electron, to begin with, and it is now lost, Na^+ will have no dots. However, the charge must still be written as a superscript. </span>
<span>Therefore, the Lewis dot structure for Na^+ is just Na^[+] </span>
