: A 100 kg box is initially at rest on a horizontal surface where the coefficient of friction is 0.25. A tension force of 1000 N is exerted on the box at an angle of 37 degrees from the horizontal. What is the normal force acting on the box?What is the acceleration of the box?

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
