Answer:
it's a part of plate that moves with a plate that's the answer
Answer:
Zero
Explanation:
The work done on an object is given by:
where
F is the force applied on the object
d is the displacement of the object
is the angle between the direction of the force and the displacement
In this problem, you are pushing again a stationary wall: this means that the walls does not move. As a result, the displacement is zero: d=0. Therefore, the work done is also zero: W=0.
Answer:
Where do I answer them???
There is a relationship between the energy of a photon and its wavelength. This can be expressed as a mathematical equation shown below:
E = hc/λ
where
h is the Planck's constant equal to 6.62607004 × 10⁻³⁴ m²<span> kg / s
c is the speed of light equal to 3</span>× 10⁸ m/s
λ is the wavelength
3.5×10⁻¹⁶ J = (6.62607004 × 10⁻³⁴ m² kg / s)(3× 10⁸ m/s)/λ
Solving for λ,
λ = 56.8×10⁻⁹ m or<em> 56.8 nm</em>
Answer:
Give them assignment on the pandemic.
Explanation:
If you wish, each student can talk about some other aspect of the pandemic that seems important and interesting then you have to give them the assignment of presentation and give reward on them. The students will definitely make the presentation on other aspects of the pandemic and when they present it in the class it enhance the knowledge of other students as well.
