Option B, particle sizes, is the right answer.

Soil texture is a distribution apparatus practiced both in the field and lab to prepare soil properties based on their natural texture. Soil texture can be circumscribed adopting qualitative techniques such as texture by touch, and quantitative approaches such as the hydrometer technique. Soil texture concentrates on the particles that are less than two millimeters in broadness which incorporate clay, silt and sand.

Objects 1 and 2 attract each other with a gravitational force of 12 units. If the mass of Object 2 is tripled, then the new grav
olasank [31]

Explanation:

Fgravity = G*(mass1*mass2)/D².

G is the gravitational constant, which has the same value throughout our universe.

D is the distance between the objects.

so, if you triple one of the masses, what does that do to our equation ?

Fgravitynew = G*(3*mass1*mass2)/D²

due to the commutative property of multiplication

Fgravitynew = 3* G*(mass1*mass2)/D² = 3* Fgravity

so, the right answer is 3×12 = 36 units.

A uniform solid disk of radius 1.60 m and mass 2.30 kg rolls without slipping to the bottom of an inclined plane. If the angular
bagirrra123 [75]

To solve this problem we will use the concepts related to energy conservation. Both potential energy, such as rotational and linear kinetic energy, must be conserved, and the gain in kinetic energy must be proportional to the loss in potential energy and vice versa. This is mathematically

PE = KE_{lineal} + KE_{rotational}

mgh = \frac{1}{2}mv^2 +\frac{1}{2} I\omega^2

Where,

m = mass

v = Tangential Velocity

\omega = Angular velocity

I = Moment of Inertia

g = Gravity

Replacing the value of Inertia in a Disk and rearranging to find h, we have

mgh = \frac{1}{2}mv^2 +\frac{1}{2} I\omega^2

mgh = \frac{1}{2}mr^2\omega^2 + \frac{1}{2}(\frac{1}{2}mr^2)\omega^2 )

h = \frac{3}{4} \frac{r^2\omega^2}{g}

Replacing,

h = \frac{3}{4} \frac{(1.6)^2 (5.35)^2}{9.8}

h = 5.607m

Therefore the height of the inclined plane is 5.6m

Photons with wavelength 1 pm are incident on electrons. What is the frequency of the Compton-scattered photons at an angle of 60
natali 33 [55]

Answer:

f = 1.354*10^{20} Hz

Explanation:

By conservation of linear momentum, wavelength shift due to collision of photon to electron is given by following formula

\lambda ^{'}-\lambda =\frac{h}{m_{o}c}(1-cos\theta )

where h is plank constant = 6.626*10^{-34}

c = speed of light = 3*10^{8} m/s

scattered angle  =  60 degree

m = rest mass of electron  = 9*10^{-31}

\lambda ^{'}=10^{-12} +\frac{6.626*10^{-34}}{9*10^{-31}*3*10^{8}}(1-cos60^{o} )

\lambda ^{'}= 2.215 pm

we know that 1 pm = 10^{-12}m

f = \frac{c}{\lambda ^{'}}

f = \frac{3*10^{8}}{2.215 *10^{-12}} = 1.354*10^{20} Hz

f = 1.354*10^{20} Hz
