A 85 Kg block of ice is being pushed in a straight rough road. The force exerted on the ice 300 N and acceleration of the entire system is 10 m/s^2. What is the friction force between the ice and the rough road.
pager
imagine a pager with only one button for the letter "A" you press the button one time for "B"ou press it two times for "E" you press it five times ,for "G" its pressed seven times
explanation :
for example if the given strings abcde , then
the total number of times the button pressed 1+2+4+5
so the output is 12
input: abde
output: 12
intput:xyz
output:75
4. A racer accelerates from rest at a constant rate of 2 m/s2. (a) How fast will the racer be going at the end of 6.0 s? (b) How far has the racer traveled during this time?
(Answer: a. 12 m/s & b. 36 m)
A scientist working late at night in her low-temperature physics laboratory decides to have a cup of hot tea, but discovers the lab hot plate is broken. Not to be deterred, she puts about 8.00 oz of water, at 12.0°C, from the tap into a lab dewar (essentially a large thermos bottle) and begins shaking it up and down. With each shake the water is thrown up and falls back down a distance of 31.3 cm.
If she can complete 30 shakes per minute, how long will it take for the water to reach 77.1°C?
In a test of hypothesis about a mean, The critical value for = 0.05 and a two tailed test is 1.96. The resulting statistic value for the sample data is - 1.75.
Which is the correct decision on the null hypothesis based on the given information?
A. Reject the null hypothesis
B. Do not reject the null hypothesis
C. Change the alternative hypothesis
D. Redefine the hypothesis.
Given the following situation determine what test should be applied, write A, if it is two-tailed, B if one-tailed (left-tailed), C if one-tailed (right-tailed) and D if cannot be determined.
Comparing the survey results of votes to the actual votes received by a candidate in an election.
A government official claims that the traffic violations occurring in the city is not as much as 5 violations a day.
Prefix Suffix
Write a program to check the overlapping of one string's suffix with the prefix of another string.Input
The first line of the input will contain a string A.
The second line of the input will contain a string B.Output
The output should contain overlapping word if present else print "No overlapping".Explanation
For example, if the given two strings, A and B, are "ramisgood" "goodforall"
The output should be "good" as good overlaps as a suffix of the first string and prefix of next.
input:
ramisgood
godforall
output:
good
input-2:
finally
restforall
Write a program that dynamically allocates an array large enough to hold a user-defined number of test
scores. Once all the scores are entered, the array should be passed to a function that sorts them in
ascending order. Another function should be called that calculates the average score. The program
should display the sorted list of scores and averages with appropriate headings. Use pointer notation
rather than array notation whenever possible.
Input Validation: Do not accept negative numbers for test scores.
Example
Enter the number of test scores: 4
Enter each test score:
Test#1: 34
Test #2: 73
Test #3: 22
Test #4: 89
Sorted test scores:
Test #1: 22
Test #2: 34
Test #3: 73
Test #4: 89
Average = 54.5

9-10.In a test of hypothesis about a mean, the critical value for 𝛼=005and a two tailed
test is 1.96. The resulting statistic value for the sample data is -1.75.What is the correct decision on the null hypothesis based on the given information?
