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?
Well, darling, that all depends on your skill level and the terrain. On average, a decent skier can cover a kilometer in about 5-10 minutes. But if you're a beginner or tackling some gnarly slopes, it could take you longer than a Kardashian marriage. Just remember, it's not a race - unless you're racing, then you better haul ass!
How does the gravitational potential energy of a roller coaster cart change on a roller coaster ride?
The energy doesn't really affect the roller coaster as much as the coaster affects the energy. Potential energy is highest and kinetic energy is lowest at the crest of the roller coaster (top of the hill), then later changed to kinetic energy as it moves down into the trough (bottom). Kinetic energy is greatest and potential energy due to gravity is lowest at the trough. Also remember that KE = 1/2(mass)(velocity)2 and that GPE or potential energy due to gravity = (mass)(9.8 m/s2)(height)
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.
When should a boat operator take off in a straight line after a skier signals he is ready to go?
A boat operator should wait for the skier to signal that they are ready to go, typically by raising a hand or giving a thumbs-up. Once the skier has signaled, the operator should take off in a straight line smoothly and gradually, ensuring that the skier has a clear path and can safely get up on their skis. It's important to avoid sudden acceleration or sharp turns that might endanger the skier. Always maintain a safe distance from the skier during the start.
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.
A skier signals that he is ready to go When should the boat operator take off in a straight line?
The boat operator should take off in a straight line only after the skier has signaled that they are ready by raising a hand or giving a specific signal. It's crucial to ensure that the skier is in a safe position and has a firm grip on the tow rope before acceleration. Once the signal is given, the operator should smoothly accelerate to avoid jerking the skier or causing an accident.
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
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.
