Answer:
t_total = 6.99 s
Explanation:
It asks us how long it takes to hear the sound, for this we must look for the time (t₁) it takes for the sound to reach the microphone, the time it takes for the video signal (t₂) to reach the television and the time (₃) it takes for the TV sound to reach us, so the total delay time is
t_total = t₁ + t₂ + t₂
we look for t1, it indicates that the distance x = 22m
v = x / t
t = x / v
t₁ = 22/343
t₁ = 6.41 10-2 s
time t₂
t₂ = 4500 103/3 108
t₂ = 1.5 10-5 s
time t₃
t₃ = 2/343
t₃ = 5.83 10⁻³
Total time is
t_total = t₁ + t₂ + t₃
t_total = 6.41 10⁻² + 1.5 10⁻⁵ + 0.583 10⁻²
t_total = 6.99 s
Answer:
The point will travel a distance of 15708 centimeters in 30 seconds of rotation.
Explanation:
In this case, we see a disk rotating at constant rate, the travelled distance of a point on the outside rim (), in centimeters, is determined by using this expression:
(1)
Where:
- Angular speed, in radians per second.
- Radius of the disk, in centimeters.
- Time, in seconds.
If we know that , and , then the travelled distance of the point is:
The point will travel a distance of 15708 centimeters in 30 seconds of rotation.
Answer:
Explanation:
Given that,
The Camden holds a volume of
V = 2,000,000 gallons
At a height of
h = 24 m
We want to find the potential energy.
And potential energy can be calculated using
P.E = mgh
Where
m is the mass
g Is the acceleration due to gravity
h Is the height.
Given that,
Then volume is
V = 2,000,000 gallons
From research.
1 gallon ≈ 3.785 kg
Then,
2,000,000 gallons = 2,000,000 × 3.785 kg
So,
P.E = mgh
P.E = 2,000,000 × 3.785 × 9.81 × 24
P.E = 1.782 × 10^9 J.
Answer:
The answer is "Option A".
Explanation:
In the given scenario, Two metal plates were produced in contrast to values separated by a small distance and three potential points for just a slight net charge are accessible. All three points would have the same electrical energy since the power generation is consistent from both sides as well as the position is placed at a slight net value so it has the highest electrical energy.
Answer:
Explanation:
The sun keeps all of the planets in orbit around it. Without the sun, all of the planets would fly off into space (out of orbit)
