Cubic zirconium is not. Coal is not. 3. How is the mass number of an element calculated? What is an isotope?
At the crest (antinode), constructive interference takes place. 82. ANS: Sound is produced by the vibration of an object. The vibrating object collides with nearby molecules transferring energy to them. These molecules collide with other molecules transferring the sound through the medium.
25. Where in plant cells are the energy-absorbing molecules for photosynthesis located? 26. The part of cellular respiration that needs oxygen takes place inside the 27. Write the chemical formula for photosynthesis.
When the fuels combust, oxygen and fuels react, and heat released. The water then absorbed the heat from the combustion. In this experiment the calorimeter of energy is used to measure the temperature of the heat that is released from the cashew. The equation to find the energy produce during
In fact, the wax itself is burning as a vapor or gas. Objectives 1. What happens to the candle when you light it? 2. Can you prove that the candle needs oxygen in order to burn?
The distance between the forces is given by the Coulombs law through the use of the formula F=kq1q2/r2.0.1newtons = 8.99*109*3.2*10-6*7.7*10-7/r2 R= 555.78 Answer to question 3 • Potential difference between the two plates is equal to velocity which is equal to 6.0*106m/s • Force = mass *acceleration = 1.4*10-13*6.0*106 = -8254 nektons The speed of the particles are computed by the formula V=ED. This is equal to 8.5*10-6*0.15. This is equal to 84.1 Answer to question 4 Voltage = current *resistance. This implies that in this case while V is 5.0 and resistance is 1.0*103, current will be equal to 5/1.0*103, = 500 amps B the direction of the conventional current provides the electric charge movement from the positive side of the battery to its negative side as in indicated in the diagram below Answer to question 5 • This section focuses on the equivalent resistance of a circuit. The equivalent resistance will be equal to (5.0*102+1.00*103)2.
I then took the initial temperature of the water. I grabbed my marshmallow and weighed it then weighed the fork. After recording the weight I lit it on fire with the lighter. Once it had a steady burn I placed it under the beaker and stirred the water with the thermometer. Once it stopped burning, I took the final temperature of the water.
Experiment An iron plate will get slightly larger when put in a hot oven. Asking a Question Suppose an iron plate has a hole cut in the center. Will the hole get larger or smaller when the plate is heated and expansion occurs? 2. Answer the following questions: 1.
