The ___________ energy in a mechanical system is determined by adding the potential and kinetic energy together.

Answers

Answer 1

Answer:

Answer:

Mechanical energy

Explanation:

The mechanical energy in a mechanical system is the summation of its kinetic energy and its potential energy.

Mechanical Energy= Potential Energy +Kinetic energy

Potential energy is defined as the energy stored in a stable object and kinetic energy is defined as the energy of a moving object or energy required in the motion of a object.

Answer 2

Answer:

Answer:

mechanical energy

Explanation:

i believe thats the answer hope that helps

130

Answers

Answer:

Explanation:

Weight on the moon is 16.5 % of weight on earth

Weight on moon = 0.165 * 130

Weight on moon = 21 lbs

If a wave has amplitude of 2 meters, a wavelength of 2 meters, and a frequency of 10 Hz, and a period of 1 second, then at what speed is the wave moving?

Answers

Answer:

20 m/s

Explanation:

The speed of a wave is given by:

$v=\lambda f$

where

$\lambda$ is the wavelength

f is the frequency

v is the speed

For the wave in this problem,

f = 10 Hz is the frequency

$\lambda=2 m$ is the wavelength

So the speed is

$v=(10 Hz)(2 m)=20 m/s$

Well, there can be a tornado that is very severe when hot and cold air mixes making air swirl and create a triangular shaped spinning air. There are lightning storms when lightning bolts come from the sky, and there are hurricanes when there are lots of rain coming towards your way due to change in climate such as global warming, it often occurs in humid places.

Which is the best example of the concept of heredity? A. A black cat blends into its environment at night. B. A baby has his mother's hair and eye color. C. As a barnacle grows, it gets calcium for its shell from seawater. D. The sunflower will move so its flower head is always facing the sun.

Answers

B) A baby has his mother's hair and eye color

B. A baby has it's mother's hair and eye color

The reason for this is, well, heredity is the passing of traits from parents to offspring. So, a black cat blending into it's environment at night simply does not have much to do with heredity. But a baby inheriting it's mother's eye color and hair color is definitely heredity, for it was inherited.
