Catalysts are used in the oil industry to increase octane
ratings in gasoline. Octane ratings tell how much fuel has to be compressed to
promote better fuel ignition in some
cars. The catalytic effect that
would be most beneficial for the oil industry is that more products can be
formed from a given amount of material.
Answer: T= 715 N
Explanation:
The only external force (neglecting gravity) acting on the swinging mass, is the centripetal force, which. in this case, is represented by the tension in the string, so we can say:
T = mv² / r
At the moment that the mass be released, it wil continue moving in a straight line at the same tangential speed that it had just an instant before, which is the same speed included in the centripetal force expression.
So the kinetic energy will be the following:
K = 1/2 m v² = 15. 0 J
Solving for v², and replacing in the expression for T:
T = 1.9 Kg (3.97)² m²/s² / 0.042 m = 715 N
Answer:
Magnitude of y-component=7 units
Direction= angle of vector A with x-axis=
Explanation:
Explained solution is in the picture attached
Answer:
B
Explanation:
Look for the one with an x coordinate of two .... answer B
Container A has 0.5 mol of gas in 11.2 L.
P = nRT/V = 0.5(0.08206)(273.15) / 11.2 = 1 atm
Container B has 2 mol of gas in 22.4 L.
P = nRT/V = 2(0.08206)(273.15) / 22.4 = 2 atm
Container C has 1 mol ofgas in 22.4 L. P = nRT/V = 1(0.08206)(273.15) / 22.4 =1 atm
Container D has 2 mol of gas in 11.2 L.
<span>P = nRT/V = 2(0.08206)(273.15) / 11.2 = 4 atm
</span>
Therefore, the correct answer from the choices is the first option, container A and C has equal pressures.
