A car is proceeding down a 1 in 10 incline at 65kph when it’s brakes are abruptly applied. How far does it skid along the road before stopping is the wheels lock and the coefficient of friction between the tires and the road is 0.7?
C3H8 + O2 CO2 + H2O
If you start with 14.8g of C3H8 and 3.44g of O2, how many grams of H2O are produced?
Which is the limiting reagent (which reactant created less H2O? _______
How many grams of the non-limiting reagent are actually used?
How many grams of the non-limiting reagent are in excess?
Note : Balance first the equation
It becomes C3H8 +5O2 3 CO2 + 4H2O
A 60g bullet is fired at a target that presents an average resistive force to the passage of the bullet of 20kN per metre thickness of the material from which is constructed. If the bullet strikes the target at 600ms-1, what does the minimum thickness of the target have to be to stop the passage of the bullet completely?
Calculate the capacitance of a capacitor with separation distance of 800m with an area 1.25kmsquare.The permittivity of free space is 8.892*10^-13

(Convert Celsius to Fahrenheit) Write a program that reads a Celsius degree in
a double value from the console, then converts it to Fahrenheit and displays the
result. The formula for the conversion is as follows:
fahrenheit = (9 / 5) * celsius + 32
Hint: In Java, 9 / 5 is 1, but 9.0 / 5 is 1.8.
Here is a sample run:
Enter a degree in Celsius: 43
43 Celsius is 109.4 Fahrenheit
the average hour spent using the computer by 20 senior high school students during online class is 7 hour with a standard deviation of 2 hours. construct a 98% confidence interval of average hour spent by all senior high school students. identify the width of the interval
Consider the most appropriate policy for tackling each of the different types of unemployment.
The cost to ship a package is a flat fee of 75 cents plus 25 cents per pound.
1. Declare a const named CENTS_PER_POUND and initialize with 25.
2. Get the shipping weight from user input storing the weight into shipWeightPounds.
3. Using FLAT_FEE_CENTS and CENTS_PER_POUND constants, assign shipCostCents with the cost of shipping a package weighing shipWeightPounds.
Production cost is 293250,computing components cost is1035,labour cost is 4140,and the savings on reusable material is 1725,determine the number of devices produced.
A French mortar fires a projectile at an angle of 45° to horizontal with a muzzle velocity of 200m/s. A tank is advancing direct towards the mortar on a level ground at a speed of 10m/s. What should be the distance from the mortar to the tank at the instant thr mortar is fired in order to score a direct hit?
