Answer:

The correct answer to the question: What part of the rocket reaches space, would be: the upper stages.

Explanation:

In rocket launching, especially space flight rockets, the amount of stages, and where they will be detached from the entire rocket, will depend on whether the rocket is intended simply for suborbital travelling, meaning just to go around the Earth´s atmosphere and not beyond, or if they are meant for orbital travelling. In the latter case, these rockets are called multistage rockets, and usually the first two stages, will fall off as soon as they burn out all their fuel, the first within Earth´s atmosphere, the second, reaching the limits between the atmosphere and outer space. The one part that reaches outer space completely, is called the upper stage, or the topmost part. This one will do the space travelling, and will also be responsible for the final arrival back to Earth. It is the engines on these upper stages that have the capacity to break against the pull of both Earth´s and the Sun´s gravities, to reach their goal.

6kg of human blood at a temperature of 65degees celcius is mixed with 4kg of human blood ata temperature of 20 degrees celcius .

Gennadij [26K]

Answer:

$T_f=47^{\circ}$

Explanation: Two samples of blood that have different masses and temperatures and are mixed, we have to find the final temperature of the mixture. the final temperature can be found using the following formula:

$T_f=\frac{(m_1\cdot T_1+m_2T_2)}{(m_1+m_2)}\Rightarrow(1)$

(1) Formula basically tells us that the product of mass and temperature remains constant throughout, so the addition of two products of the two separate blood samples would be equal to the product of final temperature and the total mass of the mixture. Mathematically this means that:

$\mleft(m_1+m_2\mright)T_f=(m_1\cdot T_1)+(m_2T_2)$

Using (1) and plugging in the corresponding values, we get the answer as follows:

$\begin{gathered} T_f=\frac{(m_1\cdot T_1+m_2T_2)}{(m_1+m_2)}\Rightarrow(1) \\ m_1=6\operatorname{kg} \\ m_2=4\operatorname{kg} \\ T_1=65^{\circ} \\ T_2=20^{\circ} \\ \therefore\rightarrow \\ T_f=\frac{(6kg\cdot65^{\circ}+4\operatorname{kg}\cdot20^{\circ})}{(6kg+4\operatorname{kg})}=\frac{(390+80)}{10}=\frac{470}{10}=47^{\circ} \\ \therefore\rightarrow \\ T_f=47^{\circ} \end{gathered}$

A boy starts from point A and walks 3 meters toward the south, then turns around and walks 7 meters toward the north. What is th

jolli1 [7]

Answer:

-3m+7m = 4m

Explanation:

As he walks south, he is going down 3m (-3m). Then he walks up 7m (+7m).

You subtract the final position from the initial position to get displacement.

7m - 3m = 4m
