Anika [276]

Answer:

North

Explanation:

In an electromagnetic wave, the direction of the wave, the direction of the electric field and the direction of the magnetic field are all perpendicular to each other.

Therefore, we can  find the direction of the magnetic field by using the right hand rule. We have:

- Index finger: direction of motion of the wave --> toward the center of Earth

- middle finger: direction of the electric field --> west

- thumb: direction of the magnetic field --> north

So, the magnetic field points north.

When a 2.40-kg object is hung vertically on a certain light spring described by Hooke's law, the spring stretches 2.92 cm.(a) Wh
Anastasy [175]

Answer:

805.48N/m

Explanation:

According to Hookes law

F = Ke

F is the force = mg

F = 2.4×9.8 = 23.52N

e is the extension = 2.92cm = 0.0292m

Force constant K = F/e

K = 23.52/0.0292

K = 805.48N/m

Hence the force constant of the spring is 805.48N/m
