The specific weight of glycerin is 78.6 lb/ft3 . Compute its density and specific gravity. What is its specific weight in kN/m3 ?
Write a program that takes as input the marks of three tests and computes the total and average marks of the student. The program should also display 'SELECTED FOR NASA TRIP' if the total marks exceeds 250 and 'BETTER LUCK NEXT TIME'
A certain oscillator satisfies the equation of motion: 𝑥••+ 4x = 0. Initially the particle is at
the point x = √3 when it is projected towards the origin with speed 2.
2.1. Show that the position, x, of the particle at any given time, t, is given by:
x = √3 cos 2t – sin 2t.
x=2x^4 + 6x^3 + 4x + 4. none of the possible roots are actual roots of the equation. What does this mean about the roots of the polynomial?
In an electrically neutral atom, the number of protons equals the number of?
Light of wavelenght 500nm is directed normally to a double slit of 1.5mm. If the fringes is observed at a distance of 2m, what is the fringe separation? How many fringes can be observed in 1cm?
- In a certain country, the true probability of baby being a girl is 0.45.
- Among the next seven randomly selected births in this country, what is the probability that at least one of them is a boy?
Would it be a significant event if none of the next 7 births resulted in a boy? How do you know?
Light of wavelength 500nm is directed normally to double-slit of 1.5mm. If the fringes is observed at a distance of 2m, what is the finge separation? How many fringes can be observed in 1m?
