Sophia is planning on going down an 8-m water slide. Her weight is 50 N. She knows that she has gravitational potential energy (GPE) at various points on the slide. At each point, her GPE can be found by using an equation. GPE = weight × height above ground

Graph her GPE versus height every 2 m as she goes down the slide. Use height in meters above ground on the y-axis. Use GPE in Joules on the x-axis.

Height (m)
GPE (J)
Gravitational Potential Energy (GPE)

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

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.

the answer is 100. i just did this lesson and got a 100% on it. : )
