Which of the following four circuit diagrams best represents the experiment described in this problem?

1 answer:

6 0

We don't see any circuit diagrams.

This worries us for a few seconds, until we realize that we don't know anything about the experiment described in the problem either, so we don't have to worry about it at all.

The order in which atomic orbitals are filled is based on what factor?. . A- The potential energy of the orbital.. . B- The high

Gnoma [55]

The order in which atomic orbitals by electrons are filled is based on the Aufbau principle which states that orbitals are filled in increasing energy level. The answer that applies here is C. The overall energy level of the orbital.

Tarzan swings on a 36.0 m long vine initially inclined at an angle of 31.0◦ with the vertical. The acceleration of gravity if 9.

aleksandrvk [35]

Answer:

v = 10 m/s

Explanation:

Given,

Length of the vine, l = 36 m

Angle of inclination = 31.0◦ with the vertical

acceleration due to gravity = 9.81 m/s²

Using Conservation of energy

KE = PE

$\dfrac{1}{2} mv^2 = m g h$

$v = \sqrt{2gh}$

$v = \sqrt{2 g l(1-\cos \theta)$

$v = \sqrt{2\times 9.81\times 36 \times (1-\cos 31^0)$

v = 10 m/s

Hence, the speed of the swing is equal to 10 m/s

A wave travels at a constant speed. How does the wavelength change if the frequency is reduced by a factor of 3 ?

Oksanka [162]

Speed (v) = wavelength (λ) x frequency (f)

If speed is constant and frequency is reduced by factor of 3, you will need to increase wavelength by the same factor so that your changes reduce out.

Answer is A.
