consider the reaction C6H14 + 9.5O2 yields 6CO2 + &H2) at constant pressure. which response is true? 1. work may be done on or by the system as the reaction occurs, depending upon the temperature. 2. work is done on the system as the reaction occurs. 3. no work is done as the ...
Assuming that accelerations is constant, Given: a=15 ms^-2, s=14.1 m Applying kinematics equation, v^2 = u^2 + 2as Find for u since v is 0, u= sqrt(2 x -15 x -14.1) = 20.78 Solve for t, s= ut + 0.5at^2 14.1= 20.78t + 0.5(15)t^2 //Solve quadratic eqn for t t= 0.564(Ans), -3.33(...
what is 3/4 of paper in inches when 100 sheet of paper equal 3/10 inches
Assume the two planes are heading 'towards P'. For now, let's not get too wound up about the x and y aspects. We'll always 'know' the two places are at right angles to each other. First let's create two equations that represent the 'location'...
Voice. It was a public process but was done by voice.
a wheel is making 300rev/min about its center, calculate the angular velocity of any point on the wheel about the center. also find the speed of a point at a distance of 2cm from the center.
at a given instant two cars are at distances 300 and 400m from the point of intersection O oftwo straight roads crossing at a right angle and are approaching O at uniform speeds of 20 and 40m/s respectively. find the shortest distance between the cars and the time taken to rea...
two ships are steaming in opposite directions at 30 and 40km/h respectively, and when they are directly abeam a shot is fired from one. if the gun at rest gives a muzzle velocity of 800m/s. find the direction in which it must be fired to hit the other ship. gravity being negle...
