Answer:
The height of the ball after t seconds is h + vt - 16t 2 feet:
def main():
getInput()
def getInput():
h = int(input("Enter the initial height of the ball: ")) # Adding the int keyword before input() function
v = int(input("Enter the initial velocity of the ball: ")) # Same as above
isValid(h,v)
def isValid(h,v):
if ((h <= 0) or (v <= 0)):
print("Please enter positive values")
getInput()
else:
maxHeight(h,v)
def maxHeight(h,v):
t = (v/32)
maxH = (h + (v*h) - (16*t*t))
print ("\nMax Height of the Ball is: " + str(maxH) + " feet")
ballTime(h, v)
def ballTime(h,v):
t = 0
ballHeight = (h + (v*t) - (16*t*t))
while (ballHeight >= 0):
t += 0.1
ballHeight = (h + (v*t) - (16*t*t))
print ("\nThe ball will hit the ground approximately after " + str(t) + " seconds")
# Driver Code
main()
The answer is Forward.
One microsleep warning sign occurs when you catch yourself leaning <span>Forward in the drivers sea.</span> Microsleeping while driving is surprisingly common and
according to surveys, at least 10 percent admitted to having slept briefly
while at the wheel. A person is likely to fall asleep when he or she is the
driver of the vehicle and may likely lean forward because the individual does
not have anything to lean on but only the steering wheel.<span />

Options :
A.) s1 < s2
B.) s1 <= s2
C.) s1.compareTo(s2) == −1
D.) s2.compareTo(s1) < 0
E.) s1.compareTo(s2) < 0
Answer: E.) s1.compareTo(s2) < 0
Explanation: Lexicographical ordering simply means the arrangement of strings based on the how the alphabets or letters of the strings appear. It could also be explained as the dictionary ordering principle of words based on the arrangement of the alphabets. In making lexicographical comparison between strings, the compareTo () method may be employed using the format below.
If first string = s1 ; second string = s2
To compare s1 with s2, the format is ;
s1.compareTo(s2) ;
If s1 comes first, that is, before s2, the method returns a negative value, that is a value less than 0 '< 0', which is the case in the question above.
If s2 comes first, that is, before s1, the method returns a positive value, that is a value greater than 0 '> 0'.
If both are s1 and s2 are the same, the output will be 0.
Answer:
The definition of a class Telephone is given as
public class Telephone // class telephone
{
String number; // variable number of type string
static int quantity = 250;
// variable quantity of type int
static double total = 1565.92; // variable total of type double
}
Explanation:
Following is the description of Statement
- Create a class "Telephone" by using the keyword class.In that class we declared data member .
- We declared a variable "number" of type "string" which has no constructor.
- We declared a variable "quantity" of type "int" which is a static type variable. The static type variable retains the value during the program execution.
- We declared a variable "total" of type "double" which is a static type variable. The static type variable retain the value during the program execution .
