After striking both mirrors, at what angle relative to the incoming ray does the outgoing ray emerge?

1 answer:

4 0

The appropriate response is Zero degrees. The beam will leave the two mirrors along a way parallel to the one it came in on. This is the guideline of the corner reflector, which is frequently utilized as a radar target. Take note of that the corner reflector utilizes three reflecting surfaces (that are set up at 90o from each other) rather than the two like are being utilized here. Wikipedia has a truly awesome drawing that shows this two-dimentional issue pleasantly. A moment connection is given to the article on the corner reflector and the 3-D angles.

How much heat must be removed from 200 pounds of blanched vegetables at 189 degrees F to freeze them to a temperature of 22 degr

Virty [35]

To solve this problem it is necessary to apply the concepts related to heat exchange in the vegetable and water.

By definition the exchange of heat is given by

$Q =mc\Delta T$

where,

m = mass

c = specific heat

$\Delta T$ = Change in temperature

Therefore the total heat exchange is given as

$\Delta Q = Q_w+Q_v$

$\Delta Q = m_wc_w(T_i-T_f)+m_vc_v(T_i-T_f)$

Our values are given as,

Total mass is $M_T$ = 200lb ,however the mass of solid vegetable and water is given as,

$m_v= 0.4*200lb = 80lb$

$m_w=0.6*200lb=120lb$

$T_i = 183\°F\\T_f = 22\°F\\c_w = 1Btu/lbF\\c_v = 0.24Btu/lbF$

Replacing at our equation we have,

$\Delta Q = m_wc_w(T_i-T_f)+m_vc_v(T_i-T_f)$

$\Delta Q = (120)(1)(183-22)+(80)(0.24)(183-22)$

$\Delta Q = 22411.2Btu$

Therefore the heat removed is 22411.2 Btu

1.What types of geological events or changes occur at divergent plate boundaries?
Volcanoes and minor earthquakes occur at divergent plate boundaries.

2. What types of geological events or changes occur at convergent plate boundaries? Volcanoes, earthquakes and fold mountains occur at convergent plate boundaries.

3. What types of geological events or changes occur at transform plate boundaries? Earthquakes and fold mountains occur at transform plate boundaries.

4. Explain how these geological processes and interactions have changed Earth's surface through the years. Magma from volcanoes is filled with nutrients that makes land fertile. Some earthquakes make the ground shake so violently that it destroys entire landscapes and environments. Earthquakes can also cause landslides and tsunamis, which destroy whole villages, change geology and ruin natural habitats of many living creatures. When an earthquake happens in the middle of the ocean, it can create waves that are so large that they destroy coastlines, cities, and forests hundreds of miles away.
