What does the energy hill represent on a energy diagram?
The energy hill on an energy diagram represents the activation energy needed for a chemical reaction to occur. It shows the energy barrier that must be overcome for the reaction to proceed from reactants to products. The height of the hill indicates the energy input required for the reaction to take place.
What does the energy Hill on an energy diagram represent?
The additional potential energy the reactants must gain in order to react
A 2 kg ball sits at the top of a 3.2 m hill How fast does it move at the bottom of the hill?
This is an application of energy equations. Take the equation where it sets the Gravitational Potential energy (GPE) equal to the kinetic energy equation (KE) because you are trying to find velocity or how fast it moves to the bottom of the hill. mgh = 1/2mv² I will assume you know what each letter stands for, and that 10 is gravity. 2(10)(3.2) = (.5)(2)v² 64 = (1)v² or just 64 = v² Take the square of 64, and that is your answer.
How long does it take to ski a km?
The time it takes to ski a kilometer depends on numerous factors such as the skier's skill level, terrain, weather conditions, and equipment used. On average, it might take a recreational skier around 15-30 minutes to ski one kilometer. Professional skiers or experienced individuals may cover the distance much faster.
How does the gravitational potential energy of a roller coaster cart change on a roller coaster ride?
The gravitational potential energy of a roller coaster cart decreases as it moves downward due to the force of gravity. As the cart gains speed and moves to higher points in the ride, its gravitational potential energy increases. At the top of a hill or loop, the cart has its maximum potential energy, while at the bottom or in valleys, the potential energy is at its minimum.
Can you give me a sentence using the word poised?
The dancer was poised and confident as she took the stage. The senator appeared calm and poised as he addressed the crowd. The security guard watched closely, poised to take action.

A downhill skier can travel 75 miles per hour how long would it take the skier to travel 150 miles at that speed?
2 hours.
Which energy changes take place when you eat a chocolate bar run up a hill and then roll down it?
The sugar in the chocolate bar is converted to kinetic energy in the muscles, and that energy takes you up the hill. But normally you do not get that energy back by rolling down the hill because it's all absorbed in friction that you use to keep your speed in check.
A down skier can travel 75 miles per hour how long would it take the skier to travel 150 miles at speed?
Two hours. 150 divided by 75=2.
You are towing a skier behind your boat Which of these is a safety precaution you should take?
Always check the path ahead for obstacles, ensure the skier is wearing a Coast Guard-approved water flotation device, never attempt sudden or sharp turns, and if the skier falls, stop immediately.
How do you increase the potential energy of a wagon without increasing its mass?
You can increase the potential energy of a wagon by lifting it to a higher elevation. This increases its gravitational potential energy without changing its mass.
When should the vessel operator take off in a straight line After the skier has signaled he or she is ready?
When there is no traffic ahead
What kind of energy does it take to ring a hand bell?
The energy comes from the work done by the ringer in pulling the rope on the bell. This releases kinetic energy in the bell which swings and is hit by the clapper. This causes mechanical vibration in the bell and it emits sound waves.
Why is the activation energy pictured as a hill in two diagrams?
The activation energy is represented as a hill in reaction energy diagrams to illustrate the energy barrier that must be overcome for a chemical reaction to occur. The reactants must acquire enough energy to surpass this barrier before they can form products. The height of the hill represents the activation energy required for the reaction to take place.
When should the boat operator take off in a straight line when the skier signals he or she is ready to go?
when there is no traffic ahead
