The relative density of a substance is the ratio of its density to the density of liquid water, which is roughly 1000kg/m³
For example, the relative density of aluminum is 2.7, therefore it has a density of roughly 2700kg/m³
A chemical substance, element or compound. Homogeneous mixtures are complex and not easily broken down.
Explanation:
Relation between electric field and charge density is as follows.
E =
where, = charge density
= permittivity of free space =
So, = 0
or,
Now, formula to calculate the potential difference of two conductors is as follows.
It is given that,
d = 6.0 mm =
Hence, we will calculate the magnitude of the electric potential differences between the two conductors as follows.
=
= 0.0271 volts
thus, we can conclude that value of the magnitude of the electric potential differences between the two conductors is 0.0271 volts.
Answer:
7.53 m
Explanation:
Force, F = 47 N
initial velocity, u = 0
Final kinetic energy, Kf = 354 J
Let the distance traveled by the student is s.
According to the work energy theorem,
Work done by all forces = Change in kinetic energy
Force x distance = final kinetic energy - initial kinetic energy
F x s = kf - ki
47 x s = 354
s = 7.53 m
