During the period of cosmic inflation the universe underwent an extremely rapid expansion, increasing its size by a factor of 10

50 in a time of perhaps 10-32 seconds. Did this action violate the postulate of Special Relativity that nothing can travel faster than the speed of light?

Explanation:

The postulate of Special Relativity was not violated because it was the dimensions of space which were expanding. The postulate applies to objects moving through space.

The postulates of special relativity are

1. Laws are physics are same all objects in inertial frame of reference and

2. Speed of light is a constant( in vacuum) for all observers, regardless of the motion of source or the observer.

Give a qualitative description of the skydiver's motion after jumping out of the plane.​
umka2103 [35]

Explanation:

They will have not much control over their speed or rotational energy. they will carry a lot of gravitation potential energy which will get converted to kinetic energy as they fall through the atmosphere. They will reach their terminal velocity, the fastest they can travel with earth's gravity before they pull their parachute, when they use a parachute to extend their surface area, increasing wind resistance. this allows them to land safely.

A wire along the z axis carries a current of 6.4 A in the z direction Find the magnitude and direction of the force exerted on a
almond37 [142]

Answer:

The magnetic force will be 0.256 N in +y direction.                                          

Explanation:

It is given that, a wire along the z axis carries a current of 6.4 A in the z direction. Length of the wire is 8 cm. It is placed in uniform magnetic field with magnitude 0.50 T in the x direction.

The magnetic force in terms of length of wire is given by :

F=I(L\times B)\\\\F=ILB\\\\F=6.4\times 0.08\times 0.5\\\\F=0.256\ N

For direction,

F=I k(L\times Bi)\\\\F=Fj

So, the magnetic force will be 0.256 N in +y direction.
