Answer:
no
Explanation:
they cannot because they contain the same amount of liquid
When you sweat due to heat your sweat evaporates off your body taking the heat away
Answer:
T=1.384×10⁶seconds
Explanation:
Given data
p (Intensity)=1.30 kw/m²
E (Energy)=1.8×10⁹ J
A (Area)=1.00 m²
T (Time required)=?
Solution
E=PT ................eq(i)
where E is energy
P is radiation power
T is time
Radiating Power is given as
P=pA
Where p is intensity
A is Area
Put P=pA in eq(i) we get
E=pAT
T=E/pA
When you say "heavy", you're talking about the gravitational force
between that object and another object, so it depends on what the
"other object" is.
If the "other object" is, let's say, the sun, then the gravitational attraction
between the Earth and sun is about 80 times as much as the gravitational
attraction between the Moon and sun, because the Earth has about 80 times
the mass of the Moon.
But if, somehow, the weight you have in mind is the gravitational attraction
between the Earth and the Moon, then those forces are equal. The force
of gravity between two objects depends on the product of both masses,
and it's equal in both directions.
If that isn't clear to you, let me give you this additional fact that's guaranteed
to knock you even further off-balance:
Your weight on the Earth is determined by the product of
(your mass) times (the Earth's mass).
The Earth's weight on you is determined by the product of
(your mass) times (the Earth's mass).
Your weight on Earth is the same as the Earth's weight on you.
Would you like to prove it ?
-- Turn the bathroom scale upside-down, so that the step-pad
is on the floor.
-- Then step on it, so that you're standing on the bottom, which
is facing up.
-- If you placed a little mirror on the floor, so that you can read
the numbers, which are facing down toward the floor, you'll
read your own weight, even though with the scale upside-down,
you're weighing the Earth on you.
Answer:
electrostatic force = 1.08 ×
N
and if sodium ion replace by Li+ and chloride by Br− then there will be no change in electrostatic force
magnitude of electrostatic force will be same
Explanation:
given data
separation d = 0.46 nm = 4.6 ×
m
to find out
electrostatic force between Na+ and Cl− ion
and if sodium ion replace by Li+ and chloride by Br−
solution
we know electrostatic force formula that is
electrostatic force = K ×Q1×Q2 / d² .........................1
here k is coulombs constant that is = 9 ×
and Q1 and Q2 is
charge that is Q1 = + 1.6 ×
C
and Q2 = - 1.6 × C
so put all these value in equation 1
electrostatic force = K ×Q1×Q2 / d²
electrostatic force = 9 × ×1.6 × × -1.6 × / (4.6 ×)²
so electrostatic force = 1.08 × N
and if sodium ion replace by Li+ and chloride by Br− then there will be no change in electrostatic force
so magnitude of electrostatic force will be same
