Answer:

either +z direction or -z direction.

Explanation:

The direction of the electric field, in an electromagnetic wave always is perpendicular to the direction of the magnetic field and the direction of propagation of the wave.

You assume a system of coordinates with the negative x axis as the west direction, and the y axis as the up direction

In this case, the wave is propagating toward the west (- x direction), and the magnetic field vector points up (+ y direction), then, it is mandatory that the electric field vector points either +z direction or -z direction.

What is the smallest time interval in which a 5.7 T magnetic field can be turned on or off if the induced emf around the patient
VLD [36.1K]

The smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

<h3>Emf induced in the coil</h3>

The emf induced in the coil is calculated as follows;

emf = dФ/dt

where;

  • dФ is change in flux
  • dt is change in time

0.12 = 5.7/dt

dt = 5.7/0.12

dt = 47.5 s

Thus, the smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

Provide a brief summary of your selected animal, and describe why it is not extinct.
mina [271]
I'm going to say a Human.



In one simple statement, Humans have survived all of earth's devastation because of evolution. At one point it is believed that the earth had changing conditions including that some of the food that we hunted in waters became extinct. Then, as lack of food grew, We gained the ability to walk on land. As this happened, we began to adapt to our surroundings, including gaining the ability to walk on two legs and use tools

Since dimensional formula is the way of expressing physical quantity in terms of it's dimension;

Mass per unit area will be,,

Mass=M

Area=L×L=L²

Therefore dimensional formula is=ML^-2 and not M/L²

A snail con move at 3cm/s if it’s ke is 300joules what it it’s mass?
ch4aika [34]

Answer:

Explanation:  V = 3 cm/s = 0.03 m/s

                  BY THE FORmULA OF  K.E

                      K.E = 1/2 mV^2

                     300 =1/2 m (0.03)^2

                     m = 300 x 2/0.0009

                       m= 666666.66kg
