Rain water that mixes with sewage has two effects on treatment plant performance. The first issue is that it thins out the concentration of sewage. This may sound like a good thing but it's not. Wastewater treatment is a biological process and like everything that involves living things it requires a regular food supply to survive. If you thin out the food supply you can expect the biology to perform poorly. Even so, this generally doesn't cause significant problems. Instead it just makes normal performance a little worse then returns to normal once the flow goes back down.

To study the properties of various particles, you can accelerate the particles with electric fields. A positron is a particle wi

maria [59]

Answer:

a) a = 5.03x10¹³ m/s²

b) $V_{f} = 4.4 \cdot 10^{5} m/s$

Explanation:

a) The acceleration of the positron can be found as follows:

$F = q*E$ (1)

Also,

$F = ma$ (2)

By entering equation (1) into (2), we have:

$a = \frac{F}{m} = \frac{qE}{m}$

<u>Where:</u>

F: is the electric force

m: is the particle's mass = 9.1x10⁻³¹ kg

q: is the charge of the positron = 1.6x10⁻¹⁹ C

E: is the electric field = 286 N/C

$a = \frac{qE}{m} = \frac{1.6 \cdot 10^{-19} C*286 N/C}{9.1 \cdot 10^{-31} kg} = 5.03 \cdot 10^{13} m/s^{2}$

b) The positron's speed can be calculated using the following equation:

$V_{f} = V_{0} + at$

<u>Where</u>:

$V_{f}$ : is the final speed =?

$V_{0}$ : is the initial speed =0

t: is the time = 8.70x10⁻⁹ s

$V_{f} = V_{0} + at = 0 + 5.03 \cdot 10^{13} m/s^{2}*8.70 \cdot 10^{-9} s = 4.4 \cdot 10^{5} m/s$

I hope it helps you!

In what speed does an object fall, if after 10 seconds it hits the surface of Earth?

Maru [420]

Answer:

98m/s

Explanation:

Given parameters:

Time = 10s

Unknown:

Final speed = ?

Solution:

To solve this problem, we use the expression below;

v = u + gt

v is the final velocity

u is the initial velocity = 0m/s

g is the acceleration due to gravity = 9.8m/s²

t is the time

so;

v = 0 + 9.8 x 10 = 98m/s

Anna Litical is practicing a centripetal force demonstration at home. She fills a bucket with water, ties it to a strong rope, a

dlinn [17]

Answer:

Explanation:

Suppose when bucket is half full it has a mass of 2 m rotating in a circle of radius r

When Bucket is quarter full then it has a mass of m rotating in a circle of radius r.

When an object moves in a circular path then it experiences an inward force which is given by

$F_1=\frac{2mv^2}{r}$

where v=velocity of bucket

Force in case 2 is given by

$F_2=\frac{mv^2}{r}$

Thus $F_1=2F_2$

therefore force required in half bucket is more than force required in quarter bucket full.
