Taking into account the definition of weigth, the correct answer is option A: the mass of the object is 50 kg.

First, you have to know that mass is an indicator of the amount of matter that makes up a body. Its unit in the International System is the kilogram (kg).

The mass of an object will always be the same, no matter where it is located.

On the other side, bodies are subjected to the action of forces, such as the force of gravity or electromagnetic forces.

So, weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.

The weight of an object is measured in Newton (N) and will vary according to the force of gravity that acts on it.

The expression for the calculation of the weight is:

P= m×g

where:

P is the weight of a body. m is its mass. g is the gravity or acceleration with which bodies fall.

In this case, you know that:

P= 980 Nm= ?g= 19.6 $\frac{m}{s^{2} }$

Replacing in the expression for the calculation of the weight:

980 N= m× 19.6 $\frac{m}{s^{2} }$

Solving:

m= $\frac{980 N}{19.6 \frac{m}{s^{2} } }$

m=50 kg

Finally, the correct answer is option A: the mass of the object is 50 kg.

The answer to your question is: mass = 50 kg

Explanation:

Data

g = 19.6 m/s²

W = 980 N

mass = ?

Formula

W = mg

m = W / g

Substitution

m = 980 / 19.6

m = 50 kg

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4

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
