Answer:
<h2>
<u>RANCIDITY</u><u>:</u></h2>
=> Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour. An example of rancidity is when a chips pack is exposed to atmospheric air which results in a change in taste and odor.

Answer:
Right shoe
Explanation:
Let the mass and velocity of incoming puck be m and v respectively.
Momentum of the colliding puck will be mv
In case of first case , the momentum of puck becomes zero so change in momentum after collision with left shoe
= mv - 0 = mv
If time duration of collision be t
rate of change of momentum
= mv / t
This is the force exerted by puck on the left shoe .
Now let us consider collision with right shoe
momentum after collision with right shoe
- mv
change in momentum
= mv - ( - mv ) = 2mv
If time duration of collision be t
rate of change of momentum
= 2mv / t
This is the force exerted by puck on the right shoe .
Since the force on the right shoe is more , this shoe will have greater speed
after collision.
Answer:
The engine generates a force of 11000 Newtons.
Explanation:
To determine the force, first you will need to calculate the acceleration. Acceleration is change in velocity over change in time, so in this case:
![a = \frac{\Delta v}{\Delta t}=\frac{(30-0)\frac{m}{s}}{(6 - 0 )s}=5 \frac{m}{s^2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B%2830-0%29%5Cfrac%7Bm%7D%7Bs%7D%7D%7B%286%20-%200%20%29s%7D%3D5%20%5Cfrac%7Bm%7D%7Bs%5E2%7D)
Force is then determined as
![F=ma = 2200kg\cdot 5\frac{m}{s^2}=11000N](https://tex.z-dn.net/?f=F%3Dma%20%3D%202200kg%5Ccdot%205%5Cfrac%7Bm%7D%7Bs%5E2%7D%3D11000N)
This is the forward force, i.a. one acting in the direction of the car's acceleration. we are told that there is no inefficiency in the engine and transmission, therefore this same force is generated by the engine.
