A large sled is located with rocks and sits at the top of a snowy slope as shown in the diagram below

the sled and Rock weigh a total of 1250kg the top of the slope is 100m away from the bottom and 12.0 m vertically higher than it

the sled is initially stationary and then begins to slide without friction down the incline at what speed will the sled be travelling when it reaches the bottom of the slope in ms-1



A 12 volt battery is connected a light bulb and draws 150mA of current. What is the electrical resistance of a light bulb. How much power does it consume. How much will it cost to operate this bulb for a month,if the cost of electricity is $0.11 per kilo watt

The velocity of a particle is v=v0[1-sin(xt/T)]. Knowing that the particle starts from the origin with an initial velocity vo, determine (a) its position and its acceleration at t = 3T, (b) its average velocity during the interval t = 0 to t = T.

the ratio of girls to boys in a school is 3:7. on a Monday, 1/4 of the girls were absent and 1/6 of the boys were absent. if 16 fewer learners had been absent, then 7/8 of the school would have been present. calculate the number of learners present at school that day


How much work is needed to move a −9.5 charge from ground to a point whose potential is +75 V. 


You will be given a list of tuples where each tuple indicates a point i.e. (x, y) in a 2-dimensional coordinate system. You need to write a python program to find the minimum distance and the point that is closest to the origin i.e. (0,0)

Hint:

The formula of distance =√ [ (x₂ - x₁)² + (y₂ - y₁)²]

As you are calculating the distance from the origin (0,0), you can simply use distance = √ [ (x²+y²)] 

You can create a list of distances from each point and sort that list using your personal favorite sorting algorithm.


Sample Input 1 

points = [(5,3), (2,9), (-2,7), (-3,-4), (0,6), (7,2)] 

Sample Output 1 

Minimum distance = 5.0 

Here the closest point is (-3,-4) which has a distance of 5.0 from the origin.


Sample Input 2 

points = [(1,7), (4,5), (-1,7), (-2,0), (1,1), (5,-1)] 

Sample Output 2 

Minimum distance = 1.4142135623730951 Here the closest point is (1,1) which has a distance of 1.4142135623730951 from the origin.


Assuming compression is according to the law PV = constant. Calculate the initial




volume of gas at a pressure of 2 bar which will occupy a volume of 6 m3 when it is




compressed to a pressure of 42 bar.

From a finite population consisting of digits 1, 4, 5, and 9, construct the


sampling distribution of the sample mean


a. With a sample size of 2


b. With a sample size of 3

Make a program that will accept an integer and loop for the same number of times as that of the inputted integer and input random integers and add it to the array/list one by one, per line. Afterwards, make your program accept another random integer.

Using that final integer, compare from your array/list if the final integer's value is also present in your current array/list. If so, print "Present"; otherwise, print "None".
