Correct option: D. Rejuvenated stream

The mature stream have medium velocity and the canyon walls are not steep.

The old stream have water moving at very slow pace and it has wide floodplain.

The youthful stream have narrow and steep canyon walls and the water is fast moving.

The rejuvenated stream is formed due to uplift of land raised by tectonic activity. The water flows very quickly from high elevation to low elevation and the water moves rapidly. It also have steep canyon walls.

What is the time constant of a series circuit where the capacitor is 0.330μF and the resistor is 10Ω ?
PtichkaEL [24]

Answer:

\tau=3.3*10^{-6}s

Explanation:

Take at look to the picture I attached you, using Kirchhoff's current law we get:

C*\frac{dV}{dt}+\frac{V}{R}=0

This is a separable first order differential equation, let's solve it step by step:

Express the equation this way:

\frac{dV}{V}=-\frac{1}{RC}dt

integrate both sides, the left side will be integrated from an initial voltage v to a final voltage V, and the right side from an initial time 0 to a final time t:

\int\limits^V_v {\frac{dV}{V} } =-\int\limits^t_0 {\frac{1}{RC} } \, dt

Evaluating the integrals:

ln(\frac{V}{v})=e^{\frac{-t}{RC} }

natural logarithm to both sides in order to isolate V:

V(t)=ve^{-\frac{t}{RC} }

Where the term RC is called time constant and is given by:

\tau=R*C=10*(0.330*10^{-6})=3.3*10^{-6}s

How to calculate displacement, velocity, acceleration.
WINSTONCH [101]
Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.

town q and town p were 119 km apart. van drove from town q to town p at an average speed of 70 km/h. how much sooner would be ha
Vilka [71]

Answer:

0.3 hours sooner than the normal time of arrival

Explanation:

Finding the difference in time of arrival of both speed will help know how much sooner.

Given:

Distance = 119 km

Speed 1 = 70 km/h

Speed 2 = 85 km/h

Time = Distance / Speed

For the time taken at the first speed

Time = 119/70

         = 1.7 hours

For the time taken at the second speed

Time = 119/85

        = 1.4 hours

∴ 1.7 hours - 1.4 hours

= 0.3 hours sooner
