The mission behind MCATBros is to provide quality MCAT preparation materials for free or at a very affordable cost. Before we began with our paid services, we spent 2 years creating documents, forum posts, and form answers (from 2016 to 2017) for students to make their lives easier. Below, we have listed all of our free ...With the addition of the Critical Analysis & Reasoning Skills Section, the Khan Academy MCAT Collection is now complete! It contains sample content from all four sections of the exam, including 1,100 videos and 3,000 review questions to help you study. As you know, the MCAT exam consists of four multiple-choice sections.

0.5kg of ice at -5degC is put into a vessel containing 2kg of water at 15deg C and mixed together, the result being a mixture of ice and water at 0degC.Calculate the final masses of ice and water, taking the water equivalent of the vessel as 0.15kg.The specific heat of ice is 2.04kJ/kg/K and the latent heat of fusion is 335kJ/kg. •.N (t) = N _0 0 e ^ {-kt} −kt. This states that the number of carbon-10 nuclei (N (t)) left in a sample that started out with N0 atoms decreases exponentially in time. The constant k is called the decay constant, which controls how quickly the total number of nuclei decreases. The value of the decay constant is specific to the type of decay ...The work done by the gas is equal to negative the work done on the gas because if the gas does 100 Joules of work that's, like, someone doing negative 100 Joules of work on the gas. Because if you do negative work on an object you're actually taking energy away from it. So, that's the first law of thermodynamics.Since friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s.

11 years ago. The Doppler effect is the change in frequency that you hear when a source and an observer are moving with respect to each other. The classic case is when you have an ambulance racing by you: the pitch of the siren is higher when it is moving toward you and lower as it goes away. Explore the concept of Single Slit Interference in light waves. Uncover how waves spread out at a hole due to Huygen's Principle, leading to diffraction.
