Which statement correctly describes how thermal energy tends to spontaneously flow?
True [87]
The answer is A. Heat flows from high to low. For example, when you put an ice cube in a hot drink, the heat from the drink goes to the ice cube, and that is why it melts.

Situation 6.1 A 13.5-kg box slides over a rough patch 1.75 m long on a horizontal floor. Just before entering the rough patch, t
GenaCL600 [577]
B) 14.0 N    

The way to solve this problem is to determine the kinetic energy the box had before and after the rough patch of floor. The equation for kinetic energy is: 

 E = 0.5 M V^2 

 where 

 E = Energy 

 M = Mass 

 V = velocity   

 Substituting the known values, let's calculate the before and after energy. 

 Before: 

 E = 0.5 M V^2 

 E = 0.5 13.5kg (2.25 m/s)^2 

 E = 6.75 kg 5.0625 m^2/s^2 

 E = 34.17188 kg*m^2/s^2 = 34.17188 joules   

 After: 

 E = 0.5 M V^2 

 E = 0.5 13.5kg (1.2 m/s)^2 

 E = 6.75 kg 1.44 m^2/s^2 

 E = 9.72 kg*m^2/s^2 = 9.72 Joules   

 So the box lost 34.17188 J - 9.72 J = 24.451875 J of energy over a distance of 1.75 meters. Let's calculate the loss per meter by dividing the loss by the distance.   

 24.451875 J / 1.75 m = 13.9725 J/m = 13.9725 N   

 Rounding to 1 decimal place gives 14.0 N which matches option "B".

Roadrunner speeds up from 2m/s to 10m/s in a distance of 10m. What is his acceleration?
DedPeter [7]

d = v·t + (1/2)·a·t^2

a = 10m/s^2. t = 10s

v = 0m/s. Initial velocity

d = 0·10 + 10/2 · 10^2 = 0 +5·100

d = 500m

For this study, the researcher is analyzing data by using __________ measures. A. experimental B. qualitative C. quantitative D.
DiKsa [7]

Answer:

B. qualitative

Explanation:

Since in the question it is mentioned that it takes the teacher opinion with respect to the student lunchroom that arranged the opinion in four classifications and according to that the report is also written

So this research represents the quality of the data collected as it does not specify the rating in terms of liking the student lunchroom

Therefore the correct option is B. qualitative

I need help asap!!!!<br><br><br>​
fiasKO [112]

Answer:

Option C

Explanation:

As we know, weight = mass x acceleration due to gravity.

Therefore, the alien would weigh more on Saturn as compared to Earth because the acceleration due to gravity is more on Saturn than Earth.

(11.08 > 9.8)
