Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0
The coals or wood embers that are used in fire walking have a low heat capacity. Sweat produced on the bottom of people's feet also helps form a protective water vapor. All of this together makes it possible, if moving quickly enough, to walk across hot coals without getting burned.
at first there is 10 electron in neon . 2 electron present at k shell and 8 present l shell . there is no rules of atomic structure . becomes it being wrong.
The boat will move -0.24 m and the negative sign indicates left direction.
<u>Explanation</u>:
mass of people A = 78 kg
mass of people B = 59 kg
mass of rowboat = 88 kg
Let the displacement of the boat be x
= 2.9 + x
= -2.9 + x
As net external F = 0
∑mx = 0
88 (x) + 78 (2.9 + x ) + 59 (-2.9 + x) = 0
88x + 226.2 + 78x - 171.1 + 59x = 0
225x + 55.1 = 0
x = -55.1 / 225
x = -0.24
The negative sign indicates left direction.
Answer:D
Explanation:
When the character falls off from cliff he moves away from the observer as he falls down and hence the frequency heard by observer lowers as he falls.
Therefore the pitch of the sound is lower than the original sound and decreasing as he falls
Option D is the correct choice
