What functions normally performed by the placenta would the hatchery have to perform so that the embryos survive
horrorfan [7]
The functions that would be performed both by the placenta and the hatchery so that the embryos will survive is to maintain the temperature of the embryos. The temperature should also be at the temperature where the embryos would thrive and develop.

A car on a roller coaster starts at zero speed at an elevation above the ground of 26 m. It coasts down a slope, and then climbs
nirvana33 [79]

The speed of the car at the top of the hill is 14m/s

<u>Explanation:</u>

given that

Initial velocity u of the car=0 m/s

The distance can be determined by finding out the difference between the elevation of the first slope and second slope.

elevation of the first slope=26 m

elevation of second slope=16m

distance s=26-16=10 m

acceleration due to gravity g=9.8 m/s2

speed of the car at the top of the hill can be determined by using the equation

v^2=u^2+2as\\v^2=0^2+2\times 9.8\times 10\\=196\\v=\sqrt{196} =14m/s

speed of the car at the top of the hill is 14m/s

A 0.3423 g sample of pentane, C5H12, was burned in a bomb (constant-volume) calorimeter. The temperature of the calorimeter and
Yakvenalex [24]

Answer:

16.82 kJ/g

Explanation:

The Heat energy generated by the pentance combusion caused the temperature increasing of the caloriemeter and the water inside it.

Heat energy of a substace can be calculated using

Q = mcθ

C= mc

where Q = Heat energy

          m =mass

          c = specific heat capacity

          C = heat capacity

          θ =temperature difference

(Temperature difference = final temperature - initial temperature.)

heat absorbed by water = mcθ

                                         = 1  * 4.184 * (22.82-20.22)

                                         = 10.88 J --------------(1)

heat absorbed by calorimeter = Cθ

                                                  = 2210 *(22.82-20.22)

                                                  = 5746 J ---------------(2)

Combustion energy = heat absorbed by water + heat absorbed by                                                  calorimeter

Combustion energy =  10.88+ 5746 = 5756.88 J

                                 = 5.757 kJ

heat of combustion of pentane = Combustion energy / mass

                                                    = 5.757 / 0.3423

                                                    = 16.82 kJ/g

The motor of a weed trimmer spins
tester [92]

The speed of the trimmer is not affected by the the distribution of trimmer line inside the spool. Option A

<h3>What is a weed trimmer?</h3>

The weed trimmer is a device that is used to trim the grasses on a lawn or a field. This device has a rotating shaft that does the actual trimming of the grasses.

The speed of the trimmer is not affected by the the distribution of trimmer line inside the spool thus it does not affect the amount of time required to reach 9,000 rpm speed.
