Answer:

C. 960.8°C

Explanation:

When freezing, silver changes state from liquid to solid. Also, when melting, silver changes state from solid to liquid. Therefore, the freezing point and melting point share the same temperature. In this case, 960.8°C

A car sets off from the traffic lights. It reaches a speed of 27 m/s in 18 seconds. What is its acceleration?
Katarina [22]

Answer:

1.6875m/s²

Explanation:

acceleration =  \frac{final \: velocity \:  -  \: initial \: velocity}{time \: taken}

<em> </em><em>a </em><em>=</em><em> </em><em>unknown.</em>

<em>v </em><em>(</em><em>final </em><em>velocity)</em><em> </em><em>=</em><em> </em><em>2</em><em>7</em><em>m</em><em>/</em><em>s</em>

<em>u </em><em>(</em><em>initial </em><em>velocity</em><em>)</em><em> </em><em>=</em><em> </em><em>0</em><em>m</em><em>/</em><em>s </em><em>(</em><em>as </em><em>the </em><em>car</em><em> </em><em>was </em><em>stationary </em><em>in </em><em>the </em><em>traffic </em><em>lights)</em><em>.</em>

<em>t </em><em>(</em><em>time </em><em>taken)</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>s</em>

<em>a =  \frac{27 - 0}{16}</em>

<em>acceleration</em><em> </em><em>=</em><em> </em><em>1.6875</em><em>m</em><em>/</em><em>s²</em>

hope it helps. :)

Calculate the required rate of return for Climax Inc., assuming that (1) investors expect a 4.0% rate of inflation in the future
Westkost [7]

Answer:

Required rate of return = 18.5 %

Explanation:

given,                            

rate of inflection = 4 %

risk free rate = 3 %                      

market risk premium = 5 %                    

firm has a beta  = 2.30                                  

rate of return has averaged 15.0% over the last 5 years

now,                                                                      

Nominal risk free rate = risk free rate  + inflation

                                    = 3%  +  4%

                                   = 7%

Required rate of return = Nominal risk free rate + β (RPM)

                                       = 7%       +          2.3 x 5.0%

Required rate of return = 18.5 %

If the distance between two objects decreased, what would happen to the force of gravity between them?
evablogger [386]

Answer: A- It would increase

Explanation:

According to the law of universal gravitation:

F=G\frac{m_{1}m_{2}}{r^2}  

Where:  

F is the module of the attraction force exerted between both objects

G is the universal gravitation constant.  

m_{1} and m_{2} are the masses of both objects  

r is the distance between both objects

As we can see, the gravity force is directly proportional to the mass of the bodies or objects and inversely proportional to the square of the distance that separates them.

In other words:

<h2>If we decrease the distance between both objects, the gravitational force between them will increase.  </h2>
