The metal conducts the heat, which makes cooking easier.
If the corner is rounded and is perfectly circular, then the acceleration is centripetal and is always directed toward the center.
Answer:

Explanation:
As we know that volume of cylinder is

Where v=volume , h= height or thickness and r= radius
Here,

Putting these values in the previous equation , we get

Therefore thickness is 27.5 m
Answer:
Force=7.71KN in the opposite direction
Explanation:
Given the mass of the car(M)=1000Kg
The initial speed of the car(u)=100km/hr
we know that 1km/hr=5/18 m/sec
100km/hr=100*5/18 m/sec=27.77m/sec
the distance travelled before it stops (s)=50m
let the acceleration of the car be a
The final velocity of the car is 0.
we know that 

a=7.712m/
We know that F=Ma
F=1000* 7.712=7712N=7.71KN
