Collaborative learning activities:__________.
blagie [28]

Answer:

Options A, B as well as C are the correct choices.

Explanation:

  • Collaborative learning seems to be a circumstance where learning is an educational approach as well as make an effort to understand all this together.
  • Except for personal learning, people participating in this learning draw mostly on competencies and qualifications of each other.

This form of learning isn't always linked to the perhaps one given choice. And the response to the above will still be the appropriate one.

The second-order bright fringe in a single-slit diffraction pattern is 1.35 mm from the center of the central maximum. The scree
Dafna11 [192]

Answer:

The wavelength is 754.2 nm.

Explanation:

Given that,

Diffraction pattern y= 1.35 mm

Width = 0.838 mm

Distance D= 75 cm

We need to calculate the wavelength

Using formula of diffraction pattern

y=\dfrac{m\lambda D}{d}

\lambda=\dfrac{yd}{mD}

Where, y = diffraction pattern

m = order

d = width

D = distance

Put the value into the formula

\lambda=\dfrac{1.35\times10^{-3}\times0.838\times10^{-3}}{2\times75\times10^{-2}}

\lambda=7.542\times10^{-7}\ m

\lambda=754.2\ nm

Hence, The wavelength is 754.2 nm.

A 2.00-kg, frictionless block is attached to an ideal spring with force constant 300 N/mN/m. At t=0 t=0 the block has velocity -
slega [8]

Answer:

The amplitude of the spring is 32.6 cm.

Explanation:

It is given that,

Mass of the block, m = 2 kg

Force constant of the spring, k = 300 N/m

At t = 0, the velocity of the block, v = -4 m/s

Displacement of the block, x = 0.2 mm = 0.0002 m

We need to find the amplitude of the spring. We know that the velocity in terms of amplitude and the angular velocity is given by :

v=\omega\sqrt{A^2-x^2}

\omega=\sqrt{\dfrac{k}{m}}

\omega=\sqrt{\dfrac{300}{2}}    

\omega=12.24\ rad/s

So, \dfrac{v^2}{\omega^2}+x^2=A^2

\dfrac{(-4)^2}{(12.24)^2}+(0.0002)^2=A^2            

A = 0.326 m

or

A = 32.6 cm

So, the amplitude of the spring is 32.6 cm. Hence, this is the required solution.
