Which wave top or bottom has the larger frequency

Answers

Answer 1

Answer: The question is simple and for the answer to the question above, it must be the bottom one because it has longer wavelengths and Because the bottom ones has 3 crests (wavelengths)
I hope my answer helped you somehow. Have a nice day!

Suppose a yo-yo has a center shaft that has a 0.230 cm radius and that its string is being pulled.(a) If the string is stationary and the yo-yo accelerates away from it at a rate of 1.80 m/s2, what is the angular acceleration of the yo-yo in rad/s2? rad/s2.
(b) What is the angular velocity in rad/s after 0.750 s if it starts from rest? rad/s.
(c) The outside radius of the yo-yo is 3.10 cm.What is the tangential acceleration in m/s2 of a point on its edge? m/s2

Answers

Answer:

Part a)

$\alpha = 782.6 rad/s^2$

Part B)

$\omega = 587 rad/s$

Part c)

$a_t = 24.3 m/s^2$

Explanation:

Part a)

As we know that

$a = R \alpha$

so we will have

$a = 1.80 m/s^2$

$R = 0.230 cm$

$\alpha = (a)/(R)$

$\alpha = (1.80)/(0.230 * 10^(-2))$

$\alpha = 782.6 rad/s^2$

Part B)

Angular speed of the yo-yo

$\omega = \alpha t$

so we have

$\omega = 782.6 * 0.750$

$\omega = 587 rad/s$

Part c)

Tangential acceleration is given as

$a_t = R \alpha$

$a_t = (3.10 * 10^(-2))(782.6)$

$a_t = 24.3 m/s^2$

Describe the difference between the currents that exist in the wires leading to a capacitor when these wires are connected to (a) a DC source and (b) an AC source.

Answers

Answer:

Explanation: In DC circuit, the current will flow for a short time, which is required to charge the capacitor. Once you switch it on, it spikes and the gradually decreases to almost zero (0) as the capacitor becomes fully charged.

In an AC circuit, the circuit acts as if the current is flowing throw the plates whereas is not actually flowing. The circuit acts like the AC is flowing through the capacitor.

What are 3 types of fossil fuels

Answers

The three types of fossil fuels are coal, oil, and natural gas. Coal is formed through decay of land vegetation, and is considered a solid fossil fuel. Oil is formed through the remains of marine microorganisms that are deposited on the sea floor and is known as a liquid fossil fuel. Lastly, natural gas is also formed through the remains of marine microorganisms, however, this is the gas version of a fossil fuel.

-- Solid . . . like coal
