5 0

Answer:

0 Mark

Explanation:

For all the measurements that we make we always need some reference to find the value of the reading

So all the scales have its reference marked as 0 mark

When we put one end of our measurement at that reference mark then the other end of the measurement will give the reading of our measurements.

so here the correct answer should be

0 MARK

A supersonic airplane is flying horizontally at a speed of 2650 km/h. What is the centripetal acceleration of the airplane, if i
Andrew [12]

Answer:

a_{c}=82617.65km/h^{2}\\  or\\a_{c}=6.37m/s^{2}

Explanation:

Given data

Speed v=2650 km/h

Radius r=85.0 km

To find

Centripetal Acceleration

Solution

As centripetal acceleration is given as

a_{c}=\frac{v^{2} }{r}................eq(i)

where

v is velocity

r is the radius

Substitute the given values in eq(i)

a_{c}=\frac{(2650km/h)^{2} }{85km} \\a_{c}=82617.65km/h^{2}\\  or\\a_{c}=6.37m/s^{2}

Based on the second law of thermodynamics, how would you expect a system to change over time?
Katyanochek1 [597]

Answer: B. Its randomness would increase

Explanation:

According to the <u>second law of thermodynamics</u>:  

<em>"The amount of entropy in the universe tends to increase over time"</em>

<em />

That is, in any cyclic process, entropy will increase, or remain the same.

 

So, in this context, entropy is a thermodynamic quantity defined as a criterion to predict the evolution or transformation of thermodynamic systems. In addition, it is used to measure the degree of organization of a system.  

In other words: Entropy is the measure of the disorder (or randomness) of a system and is a function of state.
