serious [3.7K]2 years ago
6 0

Answer:

f=0.1

Explanation:

Use the equation:

f=\frac{1}{T} (where T is the period)

f=\frac{1}{9} (9 comes from the period of a full wavelength)

f=0.1

What determines whether a surface produces a specular reflection or a diffuse reflection?
rjkz [21]

Answer:

Explanation:

when the surface is super smooth, the light reflects in all the same. which makes a good reflection.  Like how a very calm lake can look like a mirror. the water gets very very smooth.  or a mirror is very smooth too.   If the surface reflects like more randomly.. like when a lake is rough or wind is blowing over it .. and there a small waves it's not a good "even" reflection.

When you throw a pebble straight up with initial speed V, it reaches a maximum height H with no air resistance. At what speed sh
aev [14]

Answer:

Explanation:

Given

Initial speed is u=V

Maximum height of Pebble is H

Deriving maximum height of Pebble and considering motion in vertical direction

v^2-u^2=2 as

where v=final velocity

u=initial velocity

a=acceleration

s=Displacement

Final velocity will be zero at maximum height

0-(V)^2=2\times (-g)\cdot H

H=\frac{V^2}{2g}

i.e. maximum height is dependent on square of initial velocity

for twice the height

2H=\frac{(V')^2}{2g}

on comparing

V'=\sqrt{2}V

As a van travels along a level stretch of road with constant speed, most of the power developed by the engine is used to compens
babymother [125]

Answer:

64.10937 N

Explanation:

s = Displacement

v = Velocity

F = Force

Converting hp to W

2.75\times 746=2051.5\ W

Work

W=F\times s

Power

P=\frac{W}{t}\\\Rightarrow P=\frac{F\times s}{t}

Now

\frac{s}{t}=v

So,

P=F\times v\\\Rightarrow F=\frac{P}{v}\\\Rightarrow F=\frac{2051.5}{32}\\\Rightarrow F=64.10937\ N

The friction force acting on the van is 64.10937 N
