A force produces an acceleration of 5 ms

What side of the worm faces up when placed in the tray when dissection?

Lelechka [254]

The side of the worm that faces up when placed in the tray for dissection is the smoother side.

You can observe the organs of these tiny creatures by dissecting a preserved earthworm. In dissecting a worm, lay the worm on your dissecting tray with its dorsal side facing up.

which statements about acceleration are true? check all that apply. a. the si units of acceleration are m/s2. b. for acceleratio

tatiyna

The first thing you should know is that acceleration is a vector, therefore, it has magnitude, and direction.

By definition, we have that the vector acceleration is given by:

$a = \frac{dv}{dt}\\$

Where,

dv/dt: derived from the velocity vector with respect to time,

Therefore, the units of the vector acceleration are:

$a = \frac{\frac{m}{s}}{s}\\$

$a = \frac{m}{s^2}$

The symbol of acceleration is:

$a^{->}$

Answer:

The statements about acceleration that are true are:

a. the si units of acceleration are m/s2.

b. for acceleration, you must have a number, a unit, and a direction.

d. the symbol for acceleration is (True, only if the symbol is the same as above)

How does human activity affect erosion and sedimentation

antoniya [11.8K]

Answer:

Human activity such as soil stripping, mining dangerous agricultural practice causes and affects erosion and sedimentation.

The earth operates a balanced process such that the earth produce it self at about the same rate as it erodes. So if humans are stripping the soil at a rate greater than the rate at which the soil is forming itself, the soil wont be able to keep up, thus leading to erosion.

Sedimentation on the other hand is the process whereby by particle settle at the base of the carrying body due to the force of gravity.

As humans, mining activity most importantly at times dissolves particles which travels down to the core and are then moved to another location by erosion. this implies that the strength of the soil of that location becomes weak.

a fluid has a density of 921 kg/m^3. at a depth of 1.22 m, the fluid pressure is 122,000 Pa. what is the pressure at the top of

Zielflug [23.3K]

Answer:

Patm or the presion at the top is equal to 110977.28[Pa]

Explanation:

First we must define the absolute pressure value, which is equal to the sum of the atmospheric pressure plus the manometrial pressure.

$P_{abs} = P_{atm}+P_{man}\\where:\\P_{abs}=122000[Pa]$
