<span>Foods cook faster when placed in a pressure cooker.
This is because in the pressure cooker, the pressure on the surface
of the water is greater than the normal atmospheric pressure. Under
those conditions, the boiling temperature of water is increased.
So the food can be heated to a greater temperature than the normal
boiling point of water. That means that the food gets hotter, and it
cooks through and through faster.</span>
When you mix two chemicals then they are not the same as they were when you before you mixed them so true
Answer:
- Mass of the ball = 45 Kg
Explanation:
velocity attained by the ball:
Distance/time= 54/9 = 6m/s (meter per sec)
As work done on ball = distance * force applied
= 54*15
= 810 J ----------------- (i)
acc. to the conservation of energy:
work done = kinetic energy + potential energy
= 1/2*m* + 0(as object is on ground)
= 1/2*m*
= 1/2*36*m
= 18*m ------------------- (ii)
∵,(i) =(ii)
18*m = 810
m=810/18
m= 45kg
Answer:
The average velocity for this trip is 0 km/hr
Explanation:
We know that average velocity = total displacement/total time.
Now, its displacement is d = final position - initial position.
Since the car starts and ends at its initial position at Hither, if we assume its initial position is 0 km, then its final position is also 0 km.
So, its displacement is d = 0 km - 0 km = 0 km.
Since the total time for the round trip is 2 hours, the average velocity is
total displacement/ total time = 0 km/2 hr = 0 km/hr.
So the average velocity for this trip is 0 km/hr
Answer:
Cells
Explanation:
Non-living, it's atoms, but the smallest unit component that all living beings must have is the cell. In fact some living things can be just one cell. Every living being comes from cells, is made up of one or more cells, and cannot be considered a living organism without at least one.
