What must be true about a surface in order for diffuse reflection to occur?

balu736 [363]

Answer:

carpet

Explanation:

Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection.

The structure of carpet's surface is as shown. Thus it shows large amount of diffuse reflection.

Dan is gliding on his skateboard at 2.00 m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at

miss Akunina [59]

Answer:

The velocity of Dan is 1.13 m/s.

Explanation:

Given that,

Initial velocity of skateboard and Dan = 2.00 m/s

Velocity of skateboard = 7.00 m/s

Mass of Dan m= 40.0 kg

Mass of skateboard M= 7.00 Kg

Suppose How fast is Dan going as his feet hit the ground?

We need to calculate the initial velocity of Dan

Using conservation of momentum

$(m+M)v_{i}=mv_{f}+Mv_{f}$

Put the value into the formula

$(40.0+7.00)\times2.00=40.0\times v_{i}+7.00\times7.00$

$v_{i}=\dfrac{(40.0+7.00)\times2.00-7.00\times7.00}{40.0}$

$v_{i}=1.13\ m/s$

Hence, The velocity of Dan is 1.13 m/s.

Find the value of 15.0 N in pounds. Use the conversions 1slug=14.59kg and 1ft=0.3048m. Express your answer in pounds to three si

kotykmax [81]

Given the equivalent value to convert the units from kilograms to slug and feet to meters, we will proceed to define the equivalence of the 'Newton' in simplified units, that is,

$1N=1kg\cdot m\cdot s^{-2}$

Then,

$15.0N=15.0kg\cdot m\cdot s^{-2}$

Converting this value to British units we have that

$15N = 15.0kg\cdot m\cdot s^{-2} (\frac{1slug}{14.59kg})(\frac{1ft}{0.3048m})$

$15N = 3.37 slug \cdot ft \cdot s^{-2} (\frac{1 lb \cdot ft^{-1}}{1slug})$

$15N =3.37lb$

Therefore the value of 15.0 N in pounds is 3.37 lb.
