In a harbor, you can see sea waves traveling around the edges of small stationary boats. Why does this happen?

faust18 [17]

Below are the choices that can be found in the other sources:

A. diffraction
B. refraction 
C. reflection 
D. transmission

The answer is diffraction. It means that the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.

An escaped convict runs 1.70 km due East of the prison. He then runs due North to a friend's house. If the magnitude of the conv

olga2289 [7]

Answer:

The right approach will be "47° north of east".

Explanation:

The given values are:

East of prison

= 1.70 km

Displacement vector

= 2.50 km

Now,

The direction will be:

⇒ $Cos \ \theta =\frac{1.7}{2.5}$

⇒ $=0.68$

⇒ $\theta=47.16^{\circ}$

i,e., $\theta = 47^{\circ}$ (north of east)

A woman takes her dog Rover for a walk on a leash. To get the little pooch moving forward, she pulls on the leash with a force o

stepladder [879]

Answer:

15.97 N force is tending to pull Rover forward

Explanation:

The woman pulls on the leash with a force of 20.0 N at an angle of 37° above the horizontal. The arrangement is shown in the given figure,

We nee to find the pulling force P. The 20.0 N force has two components, 20.0 cos 37 in horizontal direction and 20.0 sin 37 in vertical direction.

The horizontal component is equal to pulling force P, which will pull Rover forward/

So, P = 20.0 cos 37 = 15.97 N

15.97 N force is tending to pull Rover forward.

yuradex [85]

Answer:

Explanation:

Formula E=F/C also E=V/d

In this case use the second formula; E=V/d

Data given; E=4N/C d=8m

So v=E X d

V=4x8=32V

k.e=eV= 2X32=64eV

A stationary 1.67-kg object is struck by a stick. The object experiences a horizontal force given by F = at - bt2, where t is th

Usimov [2.4K]

Answer:

$v_{f}$ = 3289.8 m / s

Explanation:

This exercise can be solved using the definition of momentum

I = ∫ F dt

Let's replace and calculate

I = ∫ (at - bt²) dt

We integrate

I = a t² / 2 - b t³ / 3

We evaluate between the lower limits I=0 for t = 0 s and higher I=I for t = 2.74 ms

I = a (2,74² / 2- 0) - b (2,74³ / 3 -0)

I = a 3,754 - b 6,857

We substitute the values of a and b

I = 1500 3,754 - 20 6,857

I = 5,631 - 137.14

I = 5493.9 N s

Now let's use the relationship between momentum and momentum

I = Δp = m $v_{f}$ - m v₀o

I = m $v_{f}$ - 0

$v_{f}$ = I / m

$v_{f}$ = 5493.9 /1.67

$v_{f}$ = 3289.8 m / s
