The lifetime of an electrical component normally distributed with mean 800 hrs and standard deviation of 60 hrs.
What is the probability that the component will fail before 680hrs
If standard deviation remain 60 hrs what would have been the mean to ensure that not more than 10% of the components fail before 800hrs.
Recall that the length of the box is a substitute measure for the box’s volume. Plot a graph of your results from part A.
Find the acceleration of a 1500.kg car, driven by 2200.N against 450.N of friction
When 47.4 g of KClO3 is completely decomposed, what is the theoretical yield, in grams, of O2 ?
- Predict How would the data in the diagram change if the pressure was 3 atm instead of 1 atm?
Slider crank mechanism as shown in the figure calculate the i) Acceleration of the slider B ii) Acceleration of the point E iii) Angular acceleration of the link AB OA rotates at (30+X) rad/s in counter clockwise direction (<b><i>10 marks</i></b>) X is the last digit of the student roll no. for example if the student roll no is <b><i>36</i></b> then X=36 and ω=30+36=66 rad/s.

Using diagrams and the concept of elasticity of demand to support your answer, explain how both UK rail companies and airways go about filling seats in order to maximise revenue?
Create class named PIZZA. Data field include a string for toppings( such as pepperoni), an integer for diameter in inches(such as 12), and a double for price(such as 23.70).
Include methods to get and set values for each of these fields.
B. Create an application name TESTPizza the intantiates one demonstrate the use of Pizza set and get methods.

A 10Mg truck rolling at a constant speed of 30 kph along a horizontal rail comes to an incline of slope sin 0.1. Calculate how far it will coil up the slope before coming to a halt, (a) ignoring all resistive forces, and (b) assuming the rolling vesistance is 5% of the normal reaction of the truck
