A block is initially positioned on a smooth ramp at a height h. The block is released and slides down until it hits a spring and compresses the spring a maximum distance of x as shown in the diagram above. A student believes that if the block is lifted to a height of 2h and released, then the spring will be compressed to a maximum distance of 2x because increasing the gravitational potential energy increases the elastic potential energy a. Which aspects of the student's reasoning, if any, are correct?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

the results is a decrease in air temperature with an increase of altitude.

explanation:

your answer is, orbit around the nucleus

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
