Why is dating method important? Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. Relative dating methods determine whether one sample is older or younger than another. […]
What is the rock cycle simple definition?
What is the rock cycle simple definition? The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Plate tectonic activity, along with weathering and erosional processes, are responsible for the continued recycling of […]

What is the direction of the induced current?
What is the direction of the induced current? The induced current will be counterclockwise (ccw). As the bar moves upward through the constant magnetic field region, the area of the loop decreases, so the flux through the loop decreases. By Lenz’s law, any induced current will tend to oppose the decrease. What is the direction […]

How does electricity make a magnetic field?
How does electricity make a magnetic field? When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak. Putting a piece of iron or steel inside the coil makes the magnet […]
How many kilojoules are in one mole?
How many kilojoules are in one mole? 1 kJ-mol−1 is 0.239 kcal-mol−1 or 1.04×10−2 eV per particle. At room temperature (25°C, 77°F, or 298.15 Kelvin) 1 kJ-mol−1 is 0.4034 k B T {\displaystyle k_{B}T}. How do you convert joules to kilojoules per mole? The prefix “kilo” means 1,000, so one kJ = 1,000 J. As […]
