Answer: speed up food processing
speed up plant growth
Increase fuel efficiency
Explanation:
A catalyst simply refers to a substance that leads to an increase in the reaction rate when it's added to a substance. When the activation energy is reduced by catalysts, this.hwlpa on the speeding up of a reaction.
Therefore,the functions of catalysts include speed up food processing, speeding up plant growth and increase fuel efficiency
Answer:
Explanation:
Given
velocity at A is 
For 
velocity is increasing at 
Tangential acceleration is given by





at 


thus 
Velocity in terms of Displacement is given by



When car has traveled
th of distance i.e.




on solving we get 
Thus velocity at 

(b)Acceleration when car has traveled three-fourth the way of track
normal acceleration 

Tangential acceleration 

Net acceleration 

Answer:
Correct option: B. 90%
Explanation:
The confidence interval is given by:
![CI = [\bar{x} - z\sigma_{\bar{x}} , \bar{x}+z\sigma_{\bar{x}} ]](https://tex.z-dn.net/?f=CI%20%3D%20%5B%5Cbar%7Bx%7D%20-%20z%5Csigma_%7B%5Cbar%7Bx%7D%7D%20%2C%20%5Cbar%7Bx%7D%2Bz%5Csigma_%7B%5Cbar%7Bx%7D%7D%20%5D)
If
is 190, we can find the value of
:



Now we need to find the value of
:


So the value of z is 1.71.
Looking at the z-table, the z value that gives a z-score of 1.71 is 0.0436
This value will occur in both sides of the normal curve, so the confidence level is:

The nearest CI in the options is 90%, so the correct option is B.
I think it’s manufacturing
Answer:
Option E
Explanation:
All the given statements are true except the velocity gradients normal to the flow direction are small since these are not normally small. It's true that viscous effects are present only inside the boundary layer and the fluid velocity equals the free stream velocity at the edge of the boundary layer. Moreover, Reynolds number is greater than unity and the fluid velocity is zero at the surface of the object.
