A bag of shells weighs 1.5 N. What is its mass? approximately 1.5 kilograms approximately 1.5 pounds approximately 150 grams approximately 1.5 grams

approximately 150 grams

Explanation:

The weight of an object is a product of its mass and acceleration of gravity acting upon it. Since weight (W) is force, it is measured in Newtons (N) or Kgms-²

W = mg

Where;

W = weight (N)

m = mass (kg)

g = acceleration due to gravity

g is a constant, which is approximately 10m/s²

Therefore, according to this question, the mass of a bag of shells that weighs 1.5N can be calculated thus:

m = W/g

m = 1.5/10

m = 0.15 kg

Converting 0.15kg to grams, we multiply by 1000 i.e 0.15 × 1000 = 150 grams.

Hence, the mass of the object is approximately 150grams.

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
