Answer:83.17 cm/s
Explanation:
Let positive x be negative direction and negative x be positive direction in this question
General equation of motion of SHM is
x= --------1
where is natural frequency of motion given by
=
Where K is spring constant
here A=23.7cm
And it is given it is again at 23.7 from equilibrium position having passed through the equilibrium once.
i.e. it covers this distance in sec
where T is the time period of oscillation i.e. returning to same place after T sec
therefore T=0.634 sec
differentiating equation 1 we get
v=cos
and =
=9.911rad/s
=
v=83.17 cm/s
The Lorentz force exerted on a charge moving in a magnetic field is given by:
where
q is the charge
v is the speed of the charge
B is the intensity of the magnetic field
is the angle between the directions of the field and of the velocity
The data we have in our problem are:
If we substitute these data and we rearrange the initial equation, we can calculate the speed of the particle:
so, the correct answer is
<span>1.1 × 104 m/s</span>
Answer:
Φ = Q/ε0 = q/ε0
Explanation:
The electric flux through any Gaussian surface is equal to the net charge inside the surface over the dielectric permitivity of vacuum. This is the Gauss theorem for electric flux trough a surface. In this case is not important that the suface is a surface of a cube.
I hope this is usefull for you!

The other options all directly affect algal bloom production because they affect the nutrients in the water, and an overabundance of certain nutrients in the water is what causes algal bloom.
