Answer:

The process

Explanation:

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Gears can be used to change the direction of a motor output from clock wise to counter clockwise

Nataliya [291]

Answer:

True

Explanation:

This can be done when the output gear is rotating in a counterclockwise direction. The initial direction of the clockwise gear changes when it comes in contact with the counter clockwise rotating gear. This will thus cause the motor to change its direction due to the counter clockwise rotating gear.

The acceleration of a particle moving along a straight line is given by a = −kt2 m/s2 where k is a constant and time t is in sec

RSB [31]

Answer:

$X - Xo = 54m$

k = 1/18

Explanation:

Data:

a = -k $t^{2}$ $\frac{m}{s^{2} }$

to = 0s Vo = 12m/s

t = 6s the particle chage it's moviment, so v = 0 m/s

We know that acceleration is the derivative of velocity related to time:

$a = \frac{dV}{dT}$

rearranging...

$a*dT = dV$

Then, we must integrate both sides:

$\int\limits^f_i {dV} \, dV =-k \int\limits^f_i {t^{2} } \, dT$

$V - Vo = -k\frac{t^{3} }{3}$

V = 0 because the exercise says that the car change it's direction:

$0 - 12 = -k\frac{6^{3} }{3}$

k = 1/6

In order to find X - Xo we must integer v*dT = dX

$V - Vo = -k\frac{t^{3} }{3}$

so...

$(Vo -k\frac{t^{3} }{3})dT = dX$

$\int\limits^f_i {dX} \, dX = \int\limits^f_i {Vo -k\frac{t^{3} }{3} } \, dT$

integrating...

$X - Xo = Vot -k\frac{t^{4} }{12}$

$X - Xo = 12*6 -\frac{1}{6}* \frac{6^{4} }{12}$

X - Xo = 54m

Consider two air-filled parallel-plate capacitors with circular plates. Capacitor 1 has a distance between plates d and plate ra

sergey [27]

Answer:

1/8 x C

Explanation:

The capacitance of parallel plate capacitor

= ε₀ A /d where A is area of plate and d is distance between plate.

for capacitor 1

C = ε₀ A /d

For capacitor 2

radius = R/2

Area = A / 4

Capacitance

= ε₀ (A/4) x ( 1 / 2d )

= ( 1 / 8) x (ε₀ A /d)

= 1/8 x C
