Answer:
If you are coming from study island the real answer is "decrease the rate of heat flow to the outside air."
Explanation:
I just answered it.
Explanation:
The relation between pressure and area is as follows;
Here, P is the pressure, F is the applied force and A is the area.
There is an inverse relationship between the pressure and area.
If the area is less then the pressure is more. If the area is more then the pressure is less.
It is given in the problem that It is much easier to slice a piece of pie with the edge of a sharp knife than with the edge of a pencil. The area of the edge of a pencil is more than the area of the edge of the knife. Then, less pressure is applied in case of using the edge of the pencil.
More force is required to cut the slice of pie by using pencil.
<u>Given that</u>
time (t) = 10 s ,
(S) = ?
We know that S = ut+ 1/2 a.t² m
since free fall and no air friction,
a = g = 9.81 m/s² ; initial velocity u= 0
S = 0 + [1/2 × 9.81 ×10²]
<em> S = 490.5 m </em>
Answer:
They could lose their magnetism if they are dropped too hard or banging against something (the ground)
Explanation:
the domains may bump out of alignment. hope this helps ! :)
<span>Acceleration is the change in velocity divided by time.
We can find acceleration a, by the following formula
a=v-u/t
where,
v is the final velocity (in this question v=8.0 m/s)
u is the initial velocity (since the hamster starts from rest, u=0)
t is the time taken (i,e 3.0 second)
now by applying the formula we have,
a = 8.0 - 0 / 3
= 8 / 3
= 2.65 m/s</span>²<span>
The acceleration is 2.65 meters per second squared</span>
