not sure which average this is but one of the averges is 12.5 m/s^2... it's been a while since physics so I'm a little rusty
btw, to find this average you have to divide 60 by 4 to get 15m/s^2.
next you divide 60 by 6 to get 10m/s^2.
then you add 15 and 10 to get 25.
finally, you divide 25 to get 12.5m/ s^2.
Answer:
A stream erodes the outsiders of meanders and deposits sand and gravel on the inside bends to from point bars. Both the velocity and channel depths are greatest near the outside bend and stream erode at outsides banks. In the same time sediment erodes is deposited in the slower water on the inside of the meander forming a point bar. Because the outside bank of a meander is eroded and sediment is deposited on the insde of the bend towards its outside bank. Hence in this meandering streams form an alternating series of cut banks and point bars along there course.
Answer:
Part a)
First image
second image
Part b)
First image
Second image
Explanation:
When object is placed between mirror and convex mirror
then for the first image
now from the mirror formula
here we have
For second position of image we will take object for convex mirror to be the position of image formed in plane mirror
so the distance of that image from convex mirror is
now by mirror formula
Part b)
Height of image and height of object is related by the equation
for height of second image
Answer:
The position is
Explanation:
The kinetic energy of the motion is
So apply the conservation of energy the force of the spring is the same of the kinetic energy
