Physics Homework Help to Prop up your Grades in School

Homework given at schools is never a cause for joy for the students, even those who are good in studies. However, there are subjects in humanities that prove to be much easier for students when it comes to doing their homework. After all, you do not solve numerical applying formulae when asked to do the assignment at home in language or History. But the same is not the case with homework given in science subjects, especially physics. Even though it is a very interesting subject that explains the way things in the world around us work, most students dread mastering the theories and their applications in real life. These students look for physics homework help to complete their assignments in time as otherwise they lose important marks and grades in the final exam.

Online help with your problems is a very effective method

Internet has emerged as information super highway for people around the world. Availability of fast speed internet in homes across the country has helped students greatly as they can now receive physics homework help sitting in the comfort of their own home rather than having to go to a coaching center or call in a tutor at home. Both these options are costly proposition in present times. In contrast, registering yourself with any of the many websites providing online help to students proves to be not only inexpensive but also very convenient way of receiving help in completing your physics homework.

Get answers on time to submit assignments on time

You cannot remain dependent upon your school science teacher to look after your specific problems in Physics as he has to complete the syllabus in a short time period. He therefore explains the chapters in Physics at his usual pace and expects that all students will grasp the concept. If you are not attentive or fail to understand a concept, you will need help from an expert to make the concept clear for you. This is necessary as otherwise you cannot solve problems based upon that principle. Websites solving the problems of students claim to have cracked thousands of text books to provide quick and efficient physics homework answers in a quick time. You can post a question on the website at any time of the day and also expect it to be answered by the expert teachers in as little as 2 hours time.

You can get this online help sitting in the comfort of your own home any time of the day. This is really great as you can get answers to questions given by your teacher at school as homework. This is only the start as you find that explanations given by teacher on these websites slowly and gradually start to make the concepts clear to you. This is really helpful as it goes a long way in mastering physics homework solutions on your own. Yes, as time passes and you receive continuous help from online teacher, you become proficient in Physics and become able to solve the problems on your own.

  • How much heat is required to raise the temperature of 100g of water from 10’C to 25’C? (The specific heat of wateris 4180 J/ Kg/ K)

    • I get two answers for this but i don’t know which is correct. The only difference in both of my methods lies in the conversion of Celsius to Kelvin.
      Q = m*c*rise in temperature
      m=0.1kg ; c=4180 J/Kg/K ; rise in temperature= 25’C-10’C=15’C=288K
      Q= 0.1*4180*288
      = 120,384 J

      second method is :
      Q= m*c*rise in temperature
      m=0.1kg; c=4180 J/Kg /K; rise in temperature= (273+25) – (273+10) = 298-283= 15K
      Q= 0.1*4180*15
      =6,270 J

  • We will model the behaviour of elastic arteries as they expand with each heartbeat, and store energy. Assume a radius of r at the lower diastolic pressure P1, and length L, and an inner surface area A for this cylindrical section. The blood pressure exerts a force F1 on that surface area, and when the pressure increases to P2 (systolic) the force increases to F2 and the radius increases to r + x.
    (a) Sketch a graph of force on the blood vessel surface A versus x, the increase in radius. Mark and label a quantity corresponding to elastic potential energy due to increased blood pressure.
    (b) Estimate this energy when the diastolic and systolic pressures are 10 kPa and 16 kPa, respectively, L = 27 mm, r = 5.1 mm, and the increase in radius x = 0.5 mm.
