Which statement best describes the weather shown by the purple combination of semicircles and triangles on a line on a weather m

ap? An occluded front can cause light to heavy precipitation that may last several days. A stationary front may produce rainy or snowy weather for several days. A warm front brings drizzly weather. A cold front can cause heavy rain, thunder, and lightning.

Why do scientists often take several measurements of the same object, average them together, and use the average value as the me
DaniilM [7]

Answer:

To minimize the practical errors and improve the accuracy.

Explanation:

  • Scientists take several measurements and use the average of all the measured values to minimize the practical errors due to unavoidable circumstances and be close to the true value.
  • True value is the actual value of a measured parameter without any error, it is the value which is proposed in the design of a certain object.
  • Variations may occur in the measurement due to wear and tear, dust and air pressure. It is almost impossible to create ideal surrounding for the measurement procedure.

A heat engine operating at steady state delivers a power output of 15.5 hp. The engine receives energy by heat transfer in the a
Anna007 [38]

Answer:

w_cycle = 13.68 KJ / cycle

Explanation:

Given:

- Steady power out-put W_out = 15.5 hp

- System executes 50 cycles/min

Find:

Determine the amount of work that is delivered during each cycle in kilo-joules

Solution:

- First we will convert the steady output into KW as follows:

                                 W_out = 15.5 hp

The conversion factor is 1.36 KW per hp.

                                 W_out = 15.5 [hp] * [KW] / 1.36 [hp]

                                 W_out = 11.4 [KW] or [KJ/s]

- Given that there are 50 cycles in 60 sec. We will use direct proportionality to calculate the number of cycles per second:

                       50 cycles   -----------> 60 s

                          x cycles   -----------> 1 s

                                 x = 50/60 = 0.8333 cycles /s

- Next we will compute the amount of work done per cycle:

                                 w_cycle = W_out / x

                                 w_cycle = 11.4 [KJ/s] * [s] / 0.8333 [cycles]

                                 w_cycle = 13.68 KJ / cycle

IgorLugansk [536]

Answer:

Explanation:

Using conservation of momentum

m_1=59+220=279kg

m_2=2.1kg

U_1=12m/s

U_2=-44m/s

m_1U_1+m_2U_2=(m_1+m_2)V\\\\\frac{278\times 12-2.1\times 44}{279+2.1}=V\\\\V=11.58m/s
