the method is analog forecasting method
analog forecasting method uses the past weather data and compares it with the existing one to forecast. it is a complex method since it involves remembering previous data for whether that can be triggered by a specific event.
A solid can diffuse into a liquid, but a solid cannot diffuse into another solid.
A solid can diffuse into both a liquid and another solid.
C. Use Coulomb's law F=kq1q2/r^2, where q1 and q2 are the two charges, and r is the distance between the two. Plug in q1=0.0072 C, q2=-0.0060 C, r=0.0040 m, k is the constant 9*10^9 N, F=-2.4*10^10 N, so the answer is C.
<h3><u>Given </u><u>:</u><u>-</u></h3>
- Here , The initial temperature of 3kg of water is 10° C
- The heat supplied to 3kg water is 7,700 J
- The specific heat of water is 4186 J/kg ° C
<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>
- We have to find the final temperature of water .
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>
Here, we have
- Mass = 3 kg
- Specific heat capacity = 4186 J/kg°C
- Initial temperature = 10° C
- Heat applied = 7,700J
<u>We </u><u>know </u><u>that</u><u>, </u>
- Specific heat is the heat that is required to increase the temperature of 1 kg or unit mass by 1° C or unit ° C
<u>That </u><u>is</u><u>, </u>
- Here, Change in temperature is ΔT that is, Final temperature - Initial temperature
<u>So</u><u>, </u>
<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>
Hence, The final temperature of 3kg if 7,700 J of heat supplied is 10.61 °C
It really depends on the altitude of the barometer.
-- If the picture was taken in Denver, Colorado, where the long-term
average atmospheric pressure is around 24.5", then this barometer
is showing slightly higher than normal, and good weather can be
predicted.
-- If the picture was taken anywhere along the east coast of the US,
where standard "sea level" pressure is 29.92", then this barometer
is reading alarmingly low ! There's either a hurricane in progress
right now, or one can be predicted to arrive very soon and you'd best
pick up your barometer and head inland as fast as you can.
