Assuming all three bulbs are connected properly with their conductivity creating a circuit, if one is unscrewed all bulbs would shut off causing zero emission of light to be displaced. Meaning answer D would be the closest to the right response.

Hope this helps! :)

Explain Newtons Laws

Vsevolod [243]

1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”

This law also called law of inertia

2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”

3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.

These forces are called action and reaction forces

hope it's helpful ❤❤❤❤❤❤

THANK YOU.

The aurora is caused when electrons and protons, moving in the earth's magnetic field of ≈5.0×10−5T, collide with molecules of t

Vika [28.1K]

Answer:

$r=0.341m$

Explanation:

The circular movement is produced by the magnetic field:

$F=q*v*B$

This force is a centripetal force because the electron moves in a plane perpendicular to the magnetic field. For a centripetal Force, that produces a circular orbit with a radius r:

$F=m*a=m*v^{2}/r$

If we solve these two equations in order to find r, with the mass and charge of a electron:

$qvB=mv^{2}/r\\r=mv/(qB)=9,1*10^{-31}*3*10^{6}/(1.6*10^{-19}*5*10^{-5})=0.341m$

How many normal modes of oscillation or natural frequencies does each if the following have: (

Vadim26 [7]

Each of these systems has exactly one degree of freedom and hence only one natural frequency obtained by solving the differential equation describing the respective motions. For the case of the simple pendulum of length L the governing differential equation is d^2x/dt^2 = - gx/L with the natural frequency f = 1/(2π) √(g/L). For the mass-spring system the governing differential equation is m d^2x/dt^2 = - kx (k is the spring constant) with the natural frequency ω = √(k/m). Note that the normal modes are also called resonant modes; the Wikipedia article below solves the problem for a system of two masses and two springs to obtain two normal modes of oscillation.
