the answer is correct why.
EXPLANATION:
First copy the 15 and u will × now in the no. of (9.8 ×1.5) the equal is 15 m/s -14.7m/s so we - the now the 15-14.7 and the ANSWER IS 0.3m/s.

Thermal energy always flows spontaneously from the body that is at a higher temperature to the body that has a lower temperature.
In this case, the thermal energy flows from the hot beverage that is at the temperature t1 to the ice cube at the temperature t2 until the two reach the same temperature t3.
Where:
t1> t2 <t3.
The ice cube would emit heat if the temperature of the liquid with which it comes in contact with the smaller than that of the ice.
Answer: Decreases the transparency of the atmosphere to infrared light.
Explanation: Green House gases are gases such as Carbondioxide,Methane,Water Vapor etc which are present in the Atmosphere,they trap and emit heat in the form of radiations. Green house gases act like a barrier preventing some of the radiations especially of the IR(INFRA-RED) to leave the Earth,which eventually leads to increase in the overall Temperature of the Earth.
The higher the concentration of the Green house gases,the lesser the transparency of the Atmosphere to the Infrared radiation.
