1) The minute travels the circumference of a 4 inches circle is 60 minutes:
Circumference = 2πr = 2π(2in) = 4π in
Time = 60 minutes
2) Constant angular velocity => (4π / 60) = (x / 20) => x = 4π / 3 inches
x = 4.19 inches
Answer: 4.19 inches
Question is Incomplete, Complete question is given below.
Current flowing in a circuit depends on two variables. Identify these variables and their relationship to current.
A) Current is proportionate to the conductance of the circuit and precisely proportional to the voltage applied across the circuit.
B) Current is conversely proportional to the electrical tension of the circuit and corresponds to the resistance across the circuit.
C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
D) Current is commensurate to the resistance of the circuit and directly proportional to the electric pressure applied across the circuit.
Answer:
C) Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
Explanation:
Now Ohms Law states that, "So long as a physical state of a conductor remains the potential difference applied to the conductor is directly proportional to current flowing through it."
I ∝ V
V=IR also I=V/R
where R is the Resistance
Hence, From above equation we can say that Current increases when there is increase in Voltage but Current decreases as the resistance decreases.
Hence,Current is inversely proportional to the resistance of the circuit and directly proportional to the voltage applied across the circuit.
Answer:
Longest wavelength, lowest intensity
Explanation:
It’s gonna be Oxygen ....
Computed tomography (CT) is an imaging tool that combines x-rays with computer technology to produce a more detailed, cross-sectional image of your body.
<h3>What is CT-Scane?</h3>
Computed tomography (CT) scan is a useful diagnostic tool for detecting diseases and injuries.
Computed tomography (CT) is an imaging tool that combines x-rays with computer technology to produce a more detailed, cross-sectional image of your body.
It uses a series of X-rays and a computer to produce a 3D image of soft tissues and bones.
CT is a painless, noninvasive way for your healthcare provider to diagnose conditions.
A CT scan lets your doctor see the size, shape, and position of structures that are deep inside your body, such as organs, tissues, or tumors.
Hence Computed tomography (CT) is an imaging tool that combines x-rays with computer technology to produce a more detailed, cross-sectional image of your body.
