Answer:
171.5 N
Explanation:
The gravitational force on an object due to the Earth is given by
where
m is the mass of the object
g is the acceleration due to gravity
The acceleration due to gravity at a certain height h above the Earth is given by
where:
G is the gravitational constant
is the Earth's mass
is the Earth's radius
Here,
So the acceleration due to gravity is
We know that the mass of the object is
m = 70 kg
So, the gravitational force on it is
Impermeable is a substance that is water proofed e.g glass, aluminium e.t.c <span />
W boson has +1e or - 1e charge, Z boson has 0 charge.
Leptons have +1e, -1e or 0 charge.
Photons have 0 charge.
Only quarks have a charge of +2/3e or -1/3e of an electron charge.
To be exact, only up-type quarks (Up, Down and Top quarks) have a +2/3e or two thirds of an electron charge.
So the correct answer is D) Quark.
<span>Near the equator, the patterns of convection currents are called
Hadley Cells.</span>
Hadley Cells refers to the low-latitude overturning movements that
have air increasing at the equator and air dropping at roughly latitude of 30
degree and these cells are also responsible for the trade winds in the Tropics
and control low-latitude patterns of weather.
Answer:
Maximum pressure in pascal is 497.84 pa
Explanation:
Pressure is given by 
where 
is density of water = 1000
height of the water 
is 2 inches = 
Maximum pressure in pascal is
