Answer:
Its duration is 1.85*10⁻³ s or 1.85 ms
Explanation:
The intensity of electric current I is defined as the amount of electric charge Q (measured in Coulombs) that passes through a section of a conductor in each unit of time. The letter I is used to name the Intensity and its unit is the Ampere (A).
The intensity of electric current is expressed as:
where:
I: Intensity expressed in Amps (A)
Q: Electric charge expressed in Coulombs (C)
t: Time expressed in seconds (s)
Being:
Replacing:
Solving:
19500 A*t= 36 C
t= 1.85*10⁻³ s= 1.85 ms (being 1 s= 1,000 ms)
<u><em>Its duration is 1.85*10⁻³ s or 1.85 ms</em></u>
Answer:
The distance traveled by the woman is 34.1m
Explanation:
Given
The initial height of the cliff
yo = 45m final, positition y = 0m bottom of the cliff
y = yo + ut -1/2gt²
u = 20.0m/s initial speed
g = 9.80m/s²
0 = 45.0 + 20×t –1/2×9.8×t²
0 = 45 +20t –4.9t²
Solving quadratically or by using a calculator,
t = 5.69s and –1.61s byt time cannot be negative so t = 5.69s
So this is the total time it takes for the ball to reach the ground from the height it was thrown.
The distance traveled by the woman is
s = vt
Given the speed of the woman v = 6.00m/s
Therefore
s = 6.00×5.69 = 34.14m
Approximately 34.1m to 3 significant figures.
Explanation:
P.E=MGH
Where m is mass
Where G is Acceleration Due to Gravity
Where h is Height
So the parameters are M = 20kg
G = 9.8m/s
H = 0.5meters
P.E= 20x9.8x0.5
=98J.
So Ans. is A= 98J
I believe the answer is going to B I hope this helps and good luck
The resistance of the laser whose voltage difference pushes the current through its laser diode is 2 ohms.
<h3>What is resistance?</h3>
The resistance is the opposition offered to the current flow.
According to the ohm's law, potential difference is directly proportional to the current flowing in the conductor.
V =I x R
Where R is the constant of proportionality called resistance.
Given is the potential difference V =10 Volts and the current flow of 5A, then the resistance will be
R = 10/5 = 2 ohms.
Thus, the resistance of the laser is 2 ohms.
