Modern physics theories indicate that:

a) all particles exhibit wave behavior.
b) only moving particles exhibit wave behavior.
c) only charged particles exhibit wave behavior.
d) only uncharged particles exhibit wave behavior.

A) All particles exhibit wave behavior

Explanation:

According to Modern physics,  which may also be called Quantum Physics, all matter  exhibits both wave like and particle like character.

Light and other electromagnetic waves also exhibits both wave like and particle like behavior.This is called wave particle duality.

For gross objects wave length is negligible and so they cannot be identified  as wave. But every matter behaves as a wave as well as a particle.

Compton effect gives the best example of the wave particle duality.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
