Answer:
Explanation:
Data provided
initial velocity v₀=20 cm/s at time t=3s
final velocity vf=0 at time t=8 s
Required
Average Acceleration for the interval from 3s to 8s
Solution
Acceleration can be defined as the first derivative of velocity concerning time
Response:
U = 12,205.5 J
Clarification:
To determine the internal energy of an ideal gas, use the following equation:
(1)
U: internal energy
R: ideal gas constant = 8.135 J(mol.K)
n: number of moles = 10 mol
T: the temperature of the gas = 100K
Substituting the parameter values into equation (1):
The overall internal energy for 10 moles of Oxygen at 100K is 12,205.5 J
assuming north-south is along the Y-axis and east-west along the X-axis
X = total X-displacement
from the graph, total displacement in the X-direction is computed as
X = 0 - 20 + 60 Cos45 + 0
X = 42.42 - 20
X = 22.42 m
Y = total Y-displacement
from the graph, total displacement in the Y-direction is computed as
Y = 40 + 0 + 60 Sin45 + 50
Y = 90 + 42.42
Y = 132.42 m
To calculate the magnitude of the net displacement vector, we apply the Pythagorean theorem, yielding
magnitude: Sqrt(X² + Y²) = Sqrt(22.42² + 132.42²) = 134.31 m
Direction: tan⁻¹(Y/X) = tan⁻¹(132.42/22.42) = 80.4 deg north of east
Broad questions addressed by conducting this experiment involve the effects of electric current.
Electric current measures the quantity of electric charge passing per unit time.
It results from electrons moving due to a voltage difference (high potential to low potential) between two points.
These electrons flow through wires acting as conductors.
Ohm's Law states that:
The potential difference across a conductor is proportional to the current flowing through it, assuming resistance remains the same.
A basic electrical circuit consists of a voltage source (battery) and a lamp.
Ammeters used to measure current must be connected in series with the load.
By adjusting the voltage while resistance is constant, varying current values are observed; increasing voltage produces higher current.
