London, it has hosted the 1908, 1948 and the 2012 summer olympics
Answer:
The Kinetic Theory of Matter or KTM as i will call it, states that every object is made of many many small particles (humans are made of sextillions of atoms), and that they are constantly moving and bumping each other. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
An example would be Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws.
A Cone of Depression occurs when a well pumps water from a certain area and causes a depression in a cone shape in the water table.
Hope this helps! :)
if you get it correct Brainliest is greatly appreciated
#1
length of one complete wave shape is known as wavelength
#2
Frequency is defined as number of oscillations per second or number of waves passing through a point in one second.
#3
One Time period is the time to cover one complete wavelength distance by the wave
#4
relation between time period and frequency is given as
#5
Time period of simple pendulum is given as
so it depends on length of pendulum and acceleration due to gravity
#6
amplitude of the wave is the height above the axis to which particle can attain its maximum position or its maximum height on y axis is amplitude
Answer:
m=0.5kg
h = 180 cm =1.8 mh=180cm=1.8m
Initial potential energy of the object is:
E_p=m*g*hE
p
=m∗g∗h
Kinetic energy at the surface:
E_k=\frac{mv^2}{2}E
k
=
2
mv

According to the law of conservation of energy (assuming no air resistance):
E_p = E_kE
p
=E
k
mgh=\frac{mv^2}{2}mgh=
2
mv
2
Solving for v:
v=\sqrt{2gh}v=
2gh
p=mvp=mv
So,
p= m*v = m\sqrt{2gh}p=m∗v=m
2gh
Calculating:
p= 0.5\sqrt{2*9.8*1.8}\approx 2.97 \frac{kg*m}{s}p=0.5
2∗9.8∗1.8
≈2.97
s
kg∗m
Answer:
p \approx 2.97 \frac{kg*m}{s}p≈2.97
s
kg∗m
