What is the gravitational potential energy of a 0.550-kg projectile flying with 335 m/s, 72 meters above the ground?

Fofino [41]

Answer:

GPE = 388.08 Joules.

Explanation:

Given the following data;

Mass = 0.550kg

Speed = 335 m/s

Height = 72 meters

We know that acceleration due to gravity, g is equal to 9.8 m/s²

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

$G.P.E = mgh$

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the formula, we have;

$G.P.E = 0.550 * 9.8 * 72$

GPE = 388.08 Joules.

_____ refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.

german

Answer:

Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.

Explanation:

Sensation helps us to detect changes in our physical environment.

Sensation occurs in three steps,

Sensory receptors, these detect stimuli.
Sensory stimuli are converted into electrical impulses to be decoded by the brain.
Finally, electrical impulses move along neural pathways to specific parts of the brain wherein the impulses are decoded into useful information.

Therefore, Sensation refers to the process by which people detect physical energy in the environment and encode that energy as neural signals.
