Answer:
C) Use a battery with more voltage.
Explanation:
The equation for the magnetic field around a coil is given by,
B = μ₀NI
where,
B = Magnetic flux density
μ₀ = permeability
N = number of turns per meter
I = Current in the wire
So when using a higher voltage battery, more current passes through the battery as resistance of the wire remains the same.
Answer: Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
Explanation:
Answer: Gravitational force between the two masses does not depend on the medium separating two masses.
Oceania crust is typically made up of igneous rocks such as basalt. Igneous rocks are formed when lava flows from volcanoes cool and harden.
Birds that eat insects, this is because their is more of their primary food source for them. If they're constantly there from the locust they wont have to look for food and will be able to reproduce and populate their territory. An example would be how when the Euorpean rabbit came to Australia, it took out the native competiton and was able to eat the vast amount of plants that was perfect for their diet back in Europe, but not so much for the other animals.
