Answer: False

Explanation: The circulatory system of the body consists of the heart, blood vessels and blood. The deoxygenated blood from the body is carried to the heart.

Here, the deoxygentaed blood is converted into oxygenated by removing carbon dioxide from them and making it oxygenated.

The impure blood from the body is collected by the right ventricle and transported to the lungs for purification and then transported to the body.

The correct answer is F (False)

Explanation:

In anatomy, the heart which is the organ in charge of pumping blood to all the body is divided into different sections that include the aorta, the superior vena cava, the right/left atrium, the pulmonary valve, and the right/left ventricles. In the case of the right ventricle, this is a chamber located on the right side of the hearth and the main function of this is to pump blood that is low in oxygen or de-oxygenated blood to the lungs through the pulmonary artery. On the other hand, the left ventricle pumps oxygenated blood to all the body. This implies, it is false the right ventricle transports oxygenated blood to the lungs because it pumps de-oxygenated rather than oxygenated blood.

Determine the thrust produced if 1.5 x 10^3 kg of gas exits the combustion chamber each second, with a speed of 4.00 x 10^3 m/s.

ozzi

Answer:

The thrust is $6\times 10^6\ N$

Explanation:

Given that,

Mass of gas, $m=1.5\times 10^3\ kg$

The rate at which the gas is expelling, $\dfrac{dv}{dt}=4\times 10^{3}\ m/s$

We need to find the thrust produced by the gas.

We know that force is equal to the rate of change of momentum. So,

$F=\dfrac{p}{t}$

Also, p = mv

$F=\dfrac{mv}{t}$

So,

$F=1.5\times 10^3\times 4\times 10^3\\\\F=6\times 10^6\ N$

So, the thrust is $6\times 10^6\ N$

You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the Empire State Building.

katen-ka-za [31]

Answer:

22.505 seconds

Explanation:

V =19.8m/s

V = a*to

t1 = 19.8/3.3

= 6seconds

Distance travelled during acceleration

= 1/2 x 3.3 x 6²

= 59.4m

X_total = x1 + x2

X2 = 373-59.4

X2 = 313.6m

t2 = x2/v

= 313.6/19.8

= 16.505

Total = 16.505 + 6

= 22.505 seconds

the minimum time in which an elevator can travel the 373 m from the ground floor is 22.505 seconds.

________ capture solar energy and use photosynthesis to produce sugars.

vovikov84 [41]

Answer:

Option (A)

Explanation:

The green plants are capable of synthesizing their own food, in the presence of sunlight, CO₂ and water, and in return, liberates food and oxygen (O₂). This process is known as photosynthesis. This process is possible due to the presence of chlorophyll pigments on the plant leaves.

These green plants are also known as producers, because they are able to generate food for the consumers.

Thus, the correct answer is option (A).
