Soil profile includes all the sections/ horizons of the vertical soil depth from top to bottom including the transitions from one horizon to another. A soil horizon is a distinct layer/section of soil with more or less the same texture. Therefore, a soil profile is made of soil horizons.
The correct answer for the question that is being presented above is this one: "(d) the magnitude of the normal force on the box from the ramp." A box is on a ramp that is at angle θ to the horizontal. As θ is increased from zero, and before the box slips, do the following increase, decrease, or remain the same and <span> the magnitude of the normal force on the box from the ramp.</span>
Answer:
Option c
Explanation:
Soil tilth refers to the physical condition of the soil, particularly with regards to the suitability of the soil for the growth of crop.
The determinants of the tilth in the soil incorporates the arrangement and steadiness of aggregated particles of the soil, pace of water penetration, level of air circulation, dampness content and seepage.
Thus option C follows the definition of the soil tilth.
Density = (mass) / (volume)
Volume of your block = (5cm x 5cm x 5cm) = 125 cm³
5 gm/cm³ = (mass) / (125 cm³)
Multiply each side by (125 cm³): Mass = 625 gm
Note:
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there. The density of water ice is not
5 gm/cm³. In fact, it's a little less than 1 gm/cm³. That's why
the ice floats in your soda.
The angle of reflection is the angle that the reflected ray makes with a line drawn perpendicular to the reflecting surface.
