according to ideal gas equation , we have
PV = n RT
where P = pressure , V = Volume , n = number of moles , R = gas constant and
T = temperature
the formula can be rearranged as
T = PV/(nR)
at constant temperature , the formula can be reformed as
T₁ = T₂
P₁V₁/(nR) = P₂V₂/(nR)
hence
P₁V₁ = P₂V₂
where
P₁ = initial pressure
P₂ = final pressure = 2 P₁
V₁ = initial volume
V₂ = final volume
P₁V₁ = (2 P₁ )V₂
V₁ = (2) V₂
V₂ = V₁ /2
hence the Volume is halved
Answer:
<em>529.2N </em>
Explanation:
Given parameters:
Mass of the object = 54kg
Unknown:
Gravitational force acting on the mass = ?
Solution:
To solve this problem, the gravitational force acting on this body is tantamount to the weight of the object.
So;
Weight = mg
m is the mass
g is the acceleration due to gravity
Now;
Weight = 54 x 9.8 = <em>529.2N </em>
The gravitational force acting on the object is <em>529.2N </em>
Answer:
attracted
Explanation:
Electrons are negative.
A positively charged object will attract a negatively charged object
Answer:
Explanation:
= Distance between central maxima and first minimum
m = Order = 1
d = Thickness of hair
= Wavelength = 632.8 nm
L = Distance between light source and screen = 1.25 m
Width of central maximum is given by
Distance between central maxima and first minimum is given by
Since is small
The strand of hair is thick.
