Work can be defined as change in kinetic energy
Answer:
A) R = 1019.11 Ω
B) V = 101.91 V
Explanation:
a) The resistance is given by the formula;
R = ρL/A
Where;
ρ is bulk density = 5.0 Ωm
L is length of cylinder = 1.6m
A is area = (π/4)D² = (π/4) x 0.1² = 0.007854 m²
Plugging in the relevant values, we obtain ;
R = (5 Ωm x 1.6m)/(0.007854 m²)
R = 1019.11 Ω
b) potential difference is given by;
V = RI
Thus, plugging in relevant values, we obtain;
V = 1019.11 Ω ∙ 0.1A
V = 101.91 V
Answer:
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Deposition means that all the sediments, soil, and rocks are all compressed (tightly pressed into each other) and create sedimentary rocks.
I hope this helps! :)
Answer:
The First Law of Thermodynamics relates internal energy or thermal energy, heat and work. There are some important things to consider. The first law will not tell you the amount of internal or thermal energy, but only how much it has changed. Heat is not temperature. Heat is the flow of energy from hot to cold objects. If heat flows into a system, we consider it positive. If heat flows out of a system, we consider it negative. Work can be done on or by the gas. If the volume increases, the gas is doing the work and we consider this negative. If work is done on the gas, the volume decreases and we consider this positive.
