Consider a cube with one corner at the origin and with sides of length 35 cm positioned along the xyz axes. there is an electric field < 55, 390y , 0 > n/c throughout the region that has a constant x component and a y component that increases linearly with . (assume the axis is to the right, the axis is upward, and the axis is out of the page. also assume that the back left corner of the cube is at the origin.) determine how much charge is inside the cube.

b.

explanation:

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
