Answer:

if the weight of the object is equal to the force applied, there will be no change

if the force applied is less than the weight of the object, there won't be any change

if the force application ed is greater than the weight of the object, than the object will move.

Explanation:

here the weight referred to the force of the object.

A beam of light from a laser illuminates a glass how long will a short pulse of light beam take to travel the length of the glas

Eduardwww [97]

Answer:

The time of short pulse of light beam is $2.37\times10^{-9}\ sec$

Explanation:

Given that,

A beam of light from a laser illuminates a glass.

Suppose, the length of piece is $L=25.21\times10^{-2}\ m$

Index of refraction is 2.83.

We need to calculate the speed of light pulse in glass

Using formula of speed

$v=\dfrac{c}{\mu}$

Put the value into the formula

$v=\dfrac{3\times10^{8}}{2.83}$

$v=1.06\times10^{8}\ m/s$

We need to calculate the time of short pulse of light beam

Using formula of velocity

$v=\dfrac{d}{t}$

$t=\dfrac{d}{v}$

Put the value into the formula

$t=\dfrac{25.21\times10^{-2}}{1.06\times10^{8}}$

$t=2.37\times10^{-9}\ sec$

Hence, The time of short pulse of light beam is $2.37\times10^{-9}\ sec$

A pebble is dropped from rest from the top of a tall cliff and falls 53.4 m after 3.3 s has elapsed. How much farther does it dr

jeka94

Answer:

426.84 m

Explanation:

initial velocity u = 0

time t = 3.3 s

distance travelled s = 53.4 m

acceleration due to gravity = g

s = ut + 1/2 g t²

53.4 = 0 + 1/2 g x 3.3²

g = 9.8 m /s²

For the whole length of fall

distance travelled = h

total time = 6.6 + 3.3 = 9.9 s

h = ut + 1/2 g t²

u again = 0

h = .5 x 9.8 x 9.9²

= 480.24 m

distance travelled in last 6.6 s

= 480.24 - 53.4

= 426.84 m

The Achilles tendon connects the muscles in your calf to the back of your foot. When you are sprinting, your Achilles tendon alt

zepelin [54]

Answer:

a)5mm

b)3.3%

Explanation:

first note down the what's given

$Y_{tendon} = 0.15x10^{10} N/m^{2}$

Area= $A= 1.1x10^{-4} m^{2}$

Mass of the runner= $m_{r}$ =70kg

Fmax= 8 F (since tendon can stretch 8 times of runner's weight)

= 8 $m_{r}$ g=8 x 70 x 9.8=> 5488N

L=15cm=> 0.15m

a) $We know that, Y={Fmax.L}$ /AΔL

YAΔL=Fmax. L

ΔL= $\frac{Fmax L}{YA} =\frac{5488*0.15}{0.15x10^{10}x1.1x10^{-4} }$

ΔL= $4.99x10^{-3} m$ => 5mm

b) L=15cm= 150mm

Fractional change can be determined by,

(ΔL/L) *100

= $\frac{4.99}{150} *100$

=3.33%
