The force (expressed in N), the egg experience upon hitting the ground is 3.5N.
<h3>What is Net force?</h3>
When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.
Given is an 0.07 kg egg and toss if from a window 30 m above the ground. The egg reaches and maintains a falling speed of 0.5 m/sec. Upon reaching the ground, the egg rapidly decelerates to 0 m/sec over the course of only 0.01 seconds.
<h3>Average force = Mass x acceleration</h3>
F = m x (Vf -Vi)/t
F = 0.07 x (0 - 0.5)/0.01
F = -3.5N
Thus, the magnitude of force on egg upon hitting the ground is 3.5N.

Answer:
correct option is E
power lens is - 1.667 D
Explanation:
Given data
infinity = 60 cm
to find out
power lens
solution
we know here infinity v = -60 cm because object at infinity
and we take u = - infinity
so we know that
1/f = 1/v - 1/u
1/f = 1 / -60 - 1 / -infinity
so
1/f = - 1/60
f = - 60 cm = 0.60 m
and we know power of lens = 1/f
so here
power = 1 / -0.60
power = - 1.667 D
so correct option is E
power lens is - 1.667 D
One of the most common energy transformations is the transformation between potential energy and kinetic energy. In waterfalls such as Niagara Falls, potential energy is transformed to kinetic energy. The water at the top of the falls has gravitational potential energy. As the water plunges, its velocity increases. Thanks to google!!!! LOL :)
<h3><u>Answer;</u></h3>
Sedimentary rock
Granite is uplifted by the movement of tectonic plates. It will most likely become a <em><u>sedimentary rock</u></em>.
<h3><u>Explanation</u>;</h3>
- Granite is an intrusive igneous rock that is coarse-grained and light-colored, mainly composed of feldspar and quartz. It forms from the crystallization or the cooling of magma in the Earth's crust.
- <em><u>When igneous rocks such as granite undergo weathering and erosion they form sediments that are deposited, then compacted and cemented by the movement of tectonic plates resulting to the formation of sedimentary rocks.</u></em>
