Briefly explain how einstein's special theory of relativity explains the perpendicular (right hand screw like) behavior of movin

ddd [48]

Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulate together in mathematically.

It is given Einstein's special theory of relativity.

It is find the Einstein's special theory of relativity explains the perpendicular behavior of moving charges without recourse to invoking the concept of a magnetic field.

<h2>What is Einstein's special theory of relativity?</h2>

As we know that one charge creates a field and its that field that actually exerts a force on the other charge. Here we it gives the relationship of two fields like electric field and magnetic field and gives the formula for electromagnetic objects.

Special relativity fixes the problem by the points that the magnetic force in one frame of reference easily be an electric force in other and also some of the combination of them in a frame.

Thus, Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulae together in mathematically.

Jeff is part of a trekking team. As he climbs a hill, he drops his water bottle, which has a mass of 0.25 kilograms.

yulyashka [42]

The vertical height from where Jeff dropped the bottle is 10m.

<h3>What is free falling?</h3>

When an object is released from rest in free air considering no friction, the motion is depend only on the acceleration due to gravity, g.

If we drop an object of mass m near the Earth surface from a height h, it has initial mechanical energy(P.E) of

U =mgh

When the object strikes the ground, all the potential energy converted into kinetic energy.

k.E = 1/2mv²

where v is the speed just before hitting the ground.

From energy conservation principle, initial and final mechanical energy are equal.

mgh = 1/2mv²

Given is Jeff climbs a hill. He drops his water bottle, which has a mass of 0.25 kilograms. The bottle slides down the hill and is moving at a velocity of 14 meters/second the instant it hits the ground.

The height from which bottle could fall is

h = v²/2g

Substitute the values, we get

h = (14)²/(2x9.81)

h =9.99 m

Thus, vertical height from where Jeff dropped the bottle is approximately 10m.

A person walks 30m due north, then 50m at 35 degrees. Find their total displacement.

Harman [31]

Using the cosine rule (a^2 = b^2 + c^2 - 2bc cos A), we can work out the displacement:
Displacement = a
b = 30
c = 50
A = 180 - 35 = 145 degrees.

a^2= 900 + 2500 -1500*-0.81915...
= 3400 + 1228.728...
= 4628.72...
a = 68.034...
= 68.0m (to 3s.f.).

To work out the angle from starting place, use another configuration of the cosine rule:
$cos(C)= \frac{a^{2} +b^{2}- c^{2} }{2ab}$ :
cos (C)= $\frac{4628.72...+900-2500}{2*68*30}$
= 3028.7.../4080
= 0.7423...
C = 42.069... degrees
= 042 bearing
