As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens th
MA_775_DIABLO [31]

Answer:

Watermelon is going at a speed of 13.33\ \rm m/s in downward direction

Explanation:

Given

  • Height of the Empire State building = 320 m
  • Speed of the superman = 24 m/s

since both the motion of both  watermelon and the superman is under gravity. The acceleration of both is g in downwards direction. So the relative acceleration between them is zero and when they meet the relative distance covered by them will be the height of the Empire State building.

so let t be the time when they meet given by

\dfrac{320}{24}\\t=13.33\ \rm s

Now let v be the velocity of the the watermelon when they meet given by

v=gt\\v=9.8\times13.33\\v=130.63\ \rm m/s

Two parallel plates have an area of
Murrr4er [49]

Answer:

8.85

Explanation:

The computation of the charge that must place on them in order to create 1000 N/C field between the plates is shown below:

We know that

E = (Q/A) ÷ E_o

1000 = Q ÷ 0.01×8.85× 10^-12

Q = 8.85 × 10^-12

So,

The answer is 8.85

The above formula should be applied so that the correct value could come

And, the same would be relevant

Q9. R₁ only.

Since the upper branch is cut at x, the circuit in this branch is not closed. No current will flow through this branch. In this case, the circuit becomes a series circuit and current only flows through R₁.

Q10. 3 pathways.

3 different resistors are connected in parallel, which means there will be three branches of parallel circuit, each with one resistor. Current can flow through 3 different branches, until the parallel circuits combine together again.

Two slits separated by a distance of d = 0.190 mm are located at a distance of D = 1.91 m from a screen. The screen is oriented
Svetlanka [38]

Answer:

\theta = 0.195^0

Explanation:

wavelength \lambda  = 648 nm \   = 648*10^{-9}m

d = 0.190 mm = 0.190 × 10⁻³ m

D = 1.91 m

By using the formula:

dsin \theta = n \lambda\\\\\theta = sin^{(-1)}(\frac{n \lambda}{d})\\\\\\\theta = sin^{(-1)}(\frac{1*648*10^{-9}}{0.190*10^{-3}})

\theta = 0.195^0

The first maximum will appear at an angle \theta = 0.195^0 from the beam axis
