To answer this question, remember the formula ∆X = Vot + 1/2 at^2
To solve, all you have to do is plug in the numbers.
∆X = height of the ledge (the unknown)
t = time (8 seconds)
a = acceleration (9.8 m/s^2)
Vo = initial velocity
∆X = 0(8) + 1/2(9.8m/s^2)(8s)^2
∆X = 0 + 313.6 m
∆X = 313.6 meters
Your answer would be B, 313.6 meters
Answer:
The aim of layout is both to present information in a logical, coherent way and to make the important elements stand out. An additional, more understated benefit, is that a well-designed layout can make the content easier to understand.
<u>Answer:</u>
The gauge pressure is 6670.8 Pascal
<u>Explanation:</u>
Given the height is 0.68 m
The Gauge pressure is determine by the formula,
Gauge pressure , P = hdg
Where h = 0.68 m
d = 1000
g = 9.81
Substituting the values in the formula of Gauge pressure, we get
Gauge Pressure = hdg =
Gauge Pressure = 6670.8
Therefore, the gauge pressure is 6670.8 Pascal
Answer:
Δt ≈ 2.9137 ≈ 3 seconds per kilometer
Explanation:
The speed of light is approximately 300000 km /s, while the speed fo the sound in the air is 0.3432 km/s.
The light takes therefore this time to travel one kilometer
On the other hand the sound takes this time to travel one kilometer
t = 2.9137 s
Then the delay time is 2.9137 -
Δt ≈ 2.9137 ≈ 3 s
The Electric current is 1.11* 10^{-4}A
Given that the coil's radius is 3.55 cm (0.35 m),
The formula for the coil's area is A = r2 A = (3.14) (0.35)2 = 0.005024 m2.
R = Resistance = 600 N = Number of spins = 500 B = Magnetic field = (0.0120)
t + (3 x 10⁻⁵) t⁴
The number t = 5 is substituted for taking the derivative at both the induced current and the electric current.
The Electric current is therefore 1.11* 10^{-4}A
Electric current - The rate of electron passage in a conductor is known as electric current. The ampere is the electric current's SI unit. Electrons are little particles that are part of a substance's molecular structure. These electrons can be held loosely or securely depending on the situation.
