17. What is your guess as to the relationship between the current in the coil and the magnetic field?

(c) Calculate the wavelength of radio waves that have frequency 200 kHz (Radio 4 LW)

a) On average, the speed of the atoms is twice the speed of the atoms at 60 K.

4. You move 26m at an angle of 40.0º W of S. (a) How far south of your starting point are you? (b) How far west are you?

(b) Due to the fact that R1 and R2 are identical, what would you guess is the voltage across each resistor is individually? Why?

13. The temperature of the water was measured prior to the tube being placed in it and the temperature of the Hydrochloric Acid was measured after it 's temperature had adjusted.

Set the radius to 2.0 m, the mass to 1.0 kg, and the velocity to 10.0 m/s.

4. A solid block of exactly 100.0 cm3 has a mass of 153.6 g. Determine its density. Will the block

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

D. A sample of gold (Au) has a mass of 26.15 g. Given that the theoretical density is 19.30 g/mL,

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

Purpose: -To understand Boyle’s and Charles’ theory. -To explain the relationship between temperature, and pressure of a gas. - To explain how the pressure in a container of gas is affected when the volume is changed.

This information ultimately supports our hypothesis. As addressed during classroom lectures, the relationship between the two variables is most likely explained by the fact that density is a ratio. It would be logical to assume that while the mass and volume increase at the same rate, the division of mass by volume would result in nearly the same number.

Topic 9 The movie Interstellar is unique among Hollywood films in that it actually tried to get the physics right. Provide an overview and a critique (which can be positive or negative) of the Special and General relativistic effects that appear in this film.

Next, theoretical velocity values were calculated, first by finding starting value, then by multiplying it by reference velocities according to equation (10) and Table1:
