Velocity is the speed with a direction and speed does not have a direction.
For example your driving 200km/hr (the speed) in a northerly direction. This is analogous to the difference between distance and displacement.
No because the top has more oxygen to it which will break the particles up and have them freeze easier.
so if something froze at the bottom of the lake it would float to the top and that's why water always freezes from the top down :))
Circuits are also known as current divider circuits because, in these circuits, the current is divided through each resistor. Whereas, series circuits are known as voltage divider circuits because here voltage is divided across all the resistors.
A) position time graph for both is shown
here one of the graph is of lesser slope which means it is moving with less speed while other have larger slope which shows larger speed
At one point they intersects which is the point where they both will meet
B) Let the two will meet after time "t"
now we can say that
if they both will meet after time "t"
then the total distance moved by you and other person will be same as the distance between you and home
so it is given as
so they will meet after t = 6 min
so from position time graph we can see that two will meet after t = 6 min where at this position two graphs will intersect
The answer is 117.6 J
The potential energy of
the object is actually its stored energy:
<span>E =
m · g · h
E - the potential energy of the object,
m - the mass of the object,
g - acceleration due to gravity,
h - the height of the object.
m = 4 kg
g = 9.8 m/s</span>²
h = 3 m
E = 4 * 9.8 * 3 = 117.6 J
