The unicorn suddenly ran through the school at 5.6 m/s and it has a mass of 450 kg. What is the unicorn’s kinetic energy?

Answers

Answer:

KE = 567000 J

planation:

The kinetic energy of the unicorn can be find out from its mass and velocity. The kinetic energy of unicorn is 7056 J.

What is kinetic energy ?

Kinetic energy is a form of energy on an object generated by virtue of its motion. It is related to the mass and velocity of the object by the expression written below:

Ke = 1/2 m v²

When an object starts moving from rest, its potential energy converts to kinetic energy. As the mass and velocity increases, kinetic energy increases.

Given that, m = 450 kg

v = 5.6 m/s

then , Ke = 1/2 450 kg × (5.6 m/s )² = 7056 J.

Therefore, the kinetic energy of the unicorn is 7056 J.

Answers

Answer:

Actually, Sherman, there are more black moths than white ones because of natural selection. The black moths blend into the environment, while the white moths do not. This means that the predators of the moths will find and eat more white moths than black moths. Then, this leads to more black moths and fewer white moths, since black moths have a better chance of surviving and reproducing.

please just answer correctlyyy

Answers

Answer:

The 2 types of vaporization are: Evaporation and Boiling. Evaporation takes place at the surface of a liquid, such as a puddle drying up.  Boiling takes place below the surface of a liquid and causes bubbling, like a pot of water on a hot stove.

Boiling and evaporation, boiling would happen when water is very hot. Evaporation would be when it’s hot out and the clouds absorb the water.

There are certain populations that work together. The right response is option C since this is a situation in which individuals of the same species collaborate in order to survive.

What did the Colville and Spokane tribes lose after the dam was built?PASSAGE:Even Grand Coulee Dam's success as a hydropower giant and agricultural dynamo could not eclipse the loss of native fish runs that had once traveled freely up the Columbia River and its tributaries. This had a devastating impact on the Colville and Spokane tribes, whose traditions and cultural ties to the land, water, and wildlife were disrupted. By 1937, the dam's slow rise from the riverbed had completely halted salmon, steelhead, and other species from reaching important tribal fishing sites like Kettle Falls on the Columbia River, and Little Falls on the Spokane River. Tribal members could no longer fish for this most valued commodity on which they depended. The annual salmon runs that anchored the tribes' yearly schedules, including the timing of their most important ceremonies, were gone. In addition, land was cleared for the dam site and reservoir. This impacted more than 3,000 homesteaders and Native Americans, who were displaced during the early design and construction phase. Tens of thousands of acres were cleared at a cost of over $10 million-- prime bottom land where Native Americans and pioneers had been living, hunting, and fishing for generations. Both the Colville and Spokane tribes were asked to relocate the remains of their ancestors by moving them to new cemeteries on higher ground.
