Answer:
True, check attachment for code
Explanation:
To convert java strings of text to upper or lower case, we can use and inbuilt methods To Uppercase and To lower case.
The first two lines of code will set up a String variable to hold the text "text to change", and then we print it out.
The third line sets of a second String variable called result.
The fourth line is where the conversion is done.
We can compare the string
We can compare one string to another. (When comparing, Java will use the hexadecimal values rather than the letters themselves.) For example, if we wanted to compare the word "Fat" with the word "App" to see which should come first, you can use an inbuilt string method called compareTo.

Answer:
maximum possible temperature is 34.088°C
Explanation:
Given data
power output Q = 37 kW
volume flow rate = 11 x 10^-5 m3/s
temperature t = 14°C
to find out
maximum possible temperature T
solution
we can say
total water volume = 4 residents × volume flow
total water volume = 4 × 11 x 10^-5 = 44 × 10^-5 m³/s
so we say total water mass = 1000 × volume
total water mass = 1000 kg/m³ × 44 × 10^-5
total water mass = 0.44 kg
we know
dQ/dt = (dm/dt)× (S)× ( T - t)
so here we know specific heat of water S = 4.186 joule/gram °C
37 = 0.44 × 4.186 × (T-14)
T = 34.088°C
maximum possible temperature is 34.088°C
Hi!
The correct answer is: C. It is the data value that appears the most often in the set.
<h3>
Explanation</h3>
The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are
A - 16 , C - 25 , D - 3
While 13 appears three times with the dishes labelled
B , E and F
So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set
<h3>Hope this helps!</h3>
Answer:
D. wood, hydrogen gas, milk, and water
Explanation:
Waves will transmit through wood, hydrogen gas, milk and water.
Waves are disturbances that propagates energy usually through a material medium.
Most mechanical waves pass through the given medium. Only electromagnetic waves do not really require a material medium for their propagation. They can be propagated through a vacuum.
A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow
