If a roller coaster train has a potential energy of 1,500 J and a kinetic energy of 500 J as it starts to travel downhill, its t

otal energy isJ. Once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 J, and its potential energy decreases to J. When the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isJ.

Food establishments may only serve food from a source that is
bezimeni [28]

A food establishment  is an operation that stores, prepares, packages, serves, vends, delivers or otherwise produces food for human consumption. Food that is offered in food establishments should come from local-approved food sources. They can use produce that they grow themselves or from agricultural producers that should be licensed and are responsible to assure that their produce is safe (complying applicable laws). The producer has to have a United States Department of Agriculture inspected plant. Food establishments should obtain produce from those who have been certified in Good Agricultural Practices and Good Handling Practices.

Challenge: To balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hyd
vladimir1956 [14]

The missing equation of the question is -

C6H12O6 + O2 ⇒ CO2 + H2O

Answer:

No, the given equation is not balanced.

Explanation:

Given equation

C6H12O6 + O2 ⇒ CO2 + H2O

for the reaction of the cellular respiration is not balanced as there are different numbers of atoms of carbon, hydrogen, and oxygen present on both sides of the arrow.

On the left side of the number of carbon, hydrogen, and oxygen atoms are more than the atoms present on the right side of the arrow. There are six carbon atoms present on the left whereas there is only one on the right side similarly hydrogen atoms are 12 and oxygen atoms are 8 in number whereas on the right side number of hydrogen are two and 3 atoms of oxygen.

The correct equation is :

C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O

Why are catfish and carp found at the mouth of a river, while trout are found nearer the source?
uysha [10]
<span>Catfish and carp require less oxygen than trout. The mouth of a river usually has less oxygen and the area closer to the source has more oxygen, so since catfish and trout require more oxygen they typically are found at the source.</span>

Determine the cause of acceleration in each scenario. An airplane turning from south to west at constant speed is accelerating d
Elden [556K]

Answer 1) : Change in direction.

Explanation : When an airplane starts to turn from south to west at constant speed gets accelerated due to change in direction. The change in direction of the airplane causes the airplane to accelerate in the direction of west while it was moving in south. Here the acceleration is being affected because of the change in direction of the object moving with a constant speed.

Answer 2) Change in direction and increasing speed.

Explanation : When a biker was riding at the speed of 5 m/s north and then changed the direction to west at an increased speed of 7 m/s this was due to increased speed and change in the direction of the bike.

There was two factors which contributed to change the acceleration in this case. It was because of change in speed of the bike and also because of change in direction. This kept the bike in acceleration by increasing the speed while changing the direction.

Answer 3) Increasing speed.

Explanation : While the shopping cart was observed to speed up on the runaway while it goes down a hill gets accelerated due to change in its speed.

In this case, when the shopping cart is been released from the upside runaway; as it goes down it gains more speed due to the slope of the runaway. This is because the acceleration is increasing because there is increase in the speed of the shopping cart.
