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:
Explanation:
The normal force exerted on the car by the walls of the cylinder at the bottom of the vertical circle will be such that when substracted to the weight it must give the centripetal force, since at that point on the vertical
We also know that the equation for the centripetal force is:
Mixing both equations we get:
Which for our values means:
Answer:
C:
Explanation:
either C or A but A seems unlikely after multiple attempts. Although the question doesn't make it clear whether the balance is electric either way it could be wrong in someway and seems to be the most likely.
Average speed is the ratio of total distance moved by Chi in total time interval
So here we will have
Total distance = 100 m + 400 m
Total time taken = 5 min + 15 min = 20 min
now by the formula of average speed we know that
so average speed will be 1.5 km/h
