An ice cube with a mass of exactly 0.2843267 kg is sliding down an incline with
an acceleration of 5 m/s^2. calculate the angle of the incline (in degrees).

i’m confused on how to find the angle can some explain?

Explanation:

Assuming there is no friction, the only force acting on the ice cube along the incline is the component of the weight of the cube parallel to the incline, that is:

where

m is the mass of the cube

g is the acceleration of gravity

is the angle of the incline

The equation of the forces along the incline therefore is

where a is the acceleration.

Here we have the following data:

Solving for , we find the angle of the incline:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
