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.
The answer is B
because if you compare a regular road and ice... ice is smoother and therefore has less friction
A vector has magnitude and direction.
Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a<u> higher frequency.</u>
<u></u>
<h3>What is the frequency?</h3>
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second. Its unit is Hz. Frequency is given by the formula as,
A moving car is targeted by radio waves sent from a radar gun by a police officer standing still.
The radio waves reflected off the vehicle and picked up by the radar gun have a greater frequency than the radio waves that were transmitted.
A stationary police officer directs radio waves emitted by a radar gun at a vehicle moving toward the officer.
Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a<u> higher frequency.</u>
Hence the higher frequency is the correct answer for blanks.
