Answer:
given,
R = 2i + j+3k
a) magnitude in x = 2
y = 1
z = 3
b) magnitude of R

R = 3.74 units
c) angle between the R and the x, y, and z axes.

θ x = 57.72°

θ y = 74.51°

θ z = 36.68°
Answer is given below
Explanation:
given data
pressure = double
volume = constant
solution
As we know that an Average velocity and rms velocity is directly proportional to square root of PV ..................1
so if we take P is doubled while keeping V constant
than Velocity increases by a factor
so that Factor = 1.414 for both the cases
Answer:
less force
Explanation:
less force because they is increase in area and not enough energy to balance the whole equation
Mechanical waves nees a material medium to propagate
Electromagnetic waves can propagate in vaccum
The big bang theory describes and claims that the universe has been created through cosmic expansion originating from a single point.
Where it was explained that the nature of now objects in space being in constant space was due to once a high density and high density point produce a scattering or explosion of the cosmic energy . Other theories have also supported this theory originally and first documented by Georges Henri Joseph Édouard Lemaître an astronomer and physicist.
