You are working for a manufacturing company, which is mathematically given as
<h3>What is the
value of m that will place the
movable bead in equilibrium at x-a a ....?</h3>
a)
Generally, the equation for the force of equilibrium is mathematically given as
F=2fcos\theta
Therefore
b)
By force equilibrium
Therefore
c)
x^2+a^2=(14/3)^{2/3}x^2
x=a/1.338
x=0.747a
d)
By force equilibrium

The magnitude of the magnetic field is 20.87 T and its direction is along positive
y direction.
The magnetic force on a particle moving in a magnetic field is given by the formula,
F = q (v x B)
Which can also be written as,
F = qvBsinθ
We know that, F = ma
So, ma = qvBsin
Putting the given values in the above equation,
1.67 x 10^-24 x 2 x 10^13 = 1.6 x 10^-19 x 10^7 x B x sin90
B = 20.87 T.
As the velocity, acceleration and magnetic field are mutually perpendicular therefore the direction of the magnetic field is along the positive y direction.
Hence, The magnitude of the magnetic field is 20.87 T and its direction is along positive
y direction.

Answer:
This is due to bending of light ray passing through the medium.
Explanation:
This can be explained using the concept of refraction.
Refraction can be defined as the bending of light ray as it travels from one medium to another (it can be from the less dense to denser medium or denser to less dense medium)
For that of pencil in water, light ray travels from less dense medium(surrounding air) to denser medium(water). This causes the pencil to bend away from the normal rather than towards the normal (angle of refraction being greater than angle of incidence) and hence the reason for the bending.
NB: Normal line is perpendicular to the plane between the medium.
Baking a cake creates a endothermic reaction. When heated, the baking soda/powder reacts, the eggs change form, and everything else follows suit. The baking soda/powder creates the rising of the cake.
D. Mineral and fossil matches from tests done on different continents.
