Answer:
D.
Explanation:
This is the essence of “correlation does not imply causation”. When there is a common cause between two variables, then they will be correlated. This is part of the reasoning behind the less-known phrase, “ There is no correlation without causation ”.
Hi there!
We can begin by calculating the voltage drop across the 30 Ω resistor using the equation:
V = IR
V = Potential Difference (V)
I = Current (A)
R = Resistance (Ω)
Calculate the voltage. Recall that the current is CONSTANT across a series circuit.
V = 0.12 × 30 = 3.6 V
Voltage ADDS UP in a series, so:
Total V = V1 + V2
6 = 3.6 + V2
<u>V2 = 2.4V. The correct answer is A.</u>
Answer:
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
Answer:
Say the object travels from to -A to +A
It will have zero velocity at both points
a) P = 2 * .19 s = .38 sec
b) f = 1 / P = 2.63 sec
c) A (amplitude) = ± A = .41 cm / 2 = 20.5 cm
You said 2 revolutions every 0.08 seconds
1 revolution = 2pi radians.
A). The 'unit rate' is (2 rev) x (2pi / 0.08 sec) = 50pi radians/sec. =
157.1 radians per sec (rounded)
B). Radius of the wheel = 30 cm
Circumference = 2pi R = 60pi cm = 188.5 cm (rounded)
Rotation speed = 2 revs per 0.08 sec
Linear speed = 2 x 60pi cm per 0.08 sec
(120pi cm) / (0.08 sec) = 47.12 meters per sec
C). Frequency = (revs) per second
= (2) / (0.08 sec) = 25 per second .
