If all the energy of a 20-g bullet travelling at 1km/s is converted into heat, how many calories are generated?
An acid solution contains 18 kg of water and pure hydrochloric acid (HCl). Its
concentration is 0.60 mol/kg of solvent. Compute for the number of moles of solute contained in the solution
Write a program to overload operators in the same program by writing suitable operator member functions for following set of expressions:
O2=++O1;
O3=O2--;
O4=!O3;
O5=-O4;
[Here O1,O2,O3,O4 and O5 are objects of a class “overloading”, and this class is having one integer data member]
given an integer value N as input write a program to print a shaded diamond of 2 *N -1 rows using an asterisk characters
Four rowers weighing 152, 156, 160, and 164 pounds make up a rowing team. Calculate the sample mean for each of the possible random samples with a size two replacement. They can be used to calculate the sample mean's probability distribution, mean, and standard deviation.
When 1.50 mol of CO2 and 1.50 mol H2 are placed in a 3.00-L container at 395ºC, the following reaction occurs: CO2(g) + H2(g) ↔ CO(g) + H2O(g).
If Kc = 0.802, what are the concentrations of each substance in the equilibrium mixture?
A concerned citizen group claims that 50% of the people in the city A support making beers illegal. Yoi decide to test this claim and ask a random sample of 315 out of 6000 people in the concerned city whether they support making beers illegal, 49% support this law. At 0.05 significance level, is there enough evidence to support this claim?
What is the shape of the sampling distribution of the means if random of size n becomes larger?
Marves wants to have a total of N$4500 in two years so he can take a trip to Harare. He finds an
account that pays 4% interest compounded monthly.
How much should Marves put into this account so that he’ll have N$4500 at the end of two
years?
