9. Given the formula c=lambda cdot v. .show how you would manipulate this equation to solve for wavelength and for frequency. (Can you show the equation for just wavelength? Just frequency?) square
A wire has a current that flows to the right. Which describes the magnetic field produced by the current? straight lines along the wire to the right moving the same direction of the current straight lines along the wire to the left moving the opposite direction of the current circles around the wire that go in at the top of the screen and moves in a counterclockwise direction circles around the wire that go in at the bottom of the screen and moves in a clockwise direction
The planet whose orbit about the Sun is most inclined is Saturn Mercury Mars Uranus
Water is placed in an ice cube tray and placed in the freezer, tuning it into ice cubes. If water is the system, what will the heat and work values be for the surroundings? a q=-,w=+ b q=+,w=+ C. q=-,w=- d q=+,w=-
The nuclear reaction is (}_{20)^45Caarrow _(2)^4He+underline ( ) for Calcium-45 undergoing alpha decay. a (}_{17)^45Ar b (}_{10)^47Ar c (}_{18)^41Ar d (}_{15)^49Ar A B C D
What is the basis for analyzing an energy transfer diagram? The mechanical energy input and output must be equal. Heat must always be the largest output. The sum of all outputs must equal the input. Electrical energy is an input but not an output.
What does it mean when work is positive? Velocity is greater than kinetic energy. Kinetic energy is greater than velocity. The environment did work on an object. An object did work on the environment.
6. How many kilocalories of heat are required to raise the temperature of 6.500 g of ice from -15.0^circ C to -1.5^circ C ? The specific heat of ice is 2.065J/(g^circ C) (4 points)
When the north pole of a bar magnet is moved into a solenoid, the needle on a galvanometer attached to the solenoid moves to the left, indicating that a current is produced. The magnet is then pulled out at a faster speed. What will be the result? a larger current in the same direction a larger current in the opposite direction a smaller current in the same direction a smaller current in the opposite direction
What is one way radio waves are used? A to carry signals for televisions B to kill germs in hospitals III to treat cancer with radiotherapy
Fill in the Blank Question Along the trajectory of a projectile, the $\square $ velocity remains constant, because there is no $\square $ in that direction. C Need help? Review these concept resources. Read About the Concept
What is the missing particle for the following nuclear decay process? ${}_{55}^{137}Cs\rightarrow _{56}^{137}Ba+?$ ${}_{1}^{0}\alpha $ ${}_{-1}^{0}\beta $ ${}_{1}^{0}\beta $ ${}_{0}^{1}n$
The diameter of a hydrogen atom is about meters. A protein molecule has an overall length of 3000 times (or $3\times 10^{3}times)$ the diameter of a hydrogen atom. What is the length of the protein molecule,. in meters , if it were written in scientific notation? $3.15\times 10^{-8}meters$ $3.15\times 10^{-12}meters$ meters $3.15\times 10^{-7}meters$
Which quantity will have the units "rad/s"? A linear displacement B angular displacement C linear velocity D angular velocity
What happens to the water pressure when water moves on a downward slope through layers of rock and soil? the water pressure increases the water pressure is unchanged the water pressure decreases the water pressure decreases then increases
An electron is a __ charged particle. a. negatively J. neutrally c. positively C B A
In order to maximize the thermal effects of ultrasound, the treatment area should be no more than three (3) times the size of the soundhead surface. True False
Question 2 (2 points) Why is Ohm's Law relevant? Ohms law is extremely important to the world of electrical circuits and components but is not suitable for every electrical circuit and application. There are certain requirements that a circuit and electrical component should meet to ensure that Ohms law is applicable. Ohms law can be used to calculate the required value of Voltage or components within a circuit, it can also work out the amount of current that flows in an electrical circuit when resistors can be measured across electrical components such as voltage. Ohm's Law is not relevant Ohm's Law is only used in a DC circuit.
What is a room designed to absorb sound called? anechoic chamber reflection chamber echo chamber absorption chamber
True or false, all else being equal, water flows with a higher velocity thorough a semi- circular channel than a wide, shallow channel. True False
