Answer:
D
Explanation:
Does not assosicate with Light
If the heart is beating at 76. 0 beats per minute, the Frequency of heart's oscillations in hertz is 1.25 Hertz.
The Frequency is defined as the number of oscillations completed in 1s.
Our heart beats continuously giving rise to the frequency of the heart.
Measuring frequency would be possible if we measure the time in seconds.
75 beats per minute means that 75 beats occur in 60s.
Frequency = Number of beats / Total time taken
Frequency = 75 / 60
Frequency = 1.25 Hz
Hence, number of beats per second is 1.25 Beats.
Beats per second or Cycles per second is same as the frequency of oscillation called as Hertz (Hz)
Hence, frequency of the heart oscillation is 1.25 Hertz (Hz).

I got it right and I hope you do as well
Answer:
1. Thermal Energy is the internal energy that is produced from the temperature of a heated substance/object.
2. From the potato to the soup and from the soup to the surrounding room
Explanation:
1. When an object or substance is heated it causes a rise in temperature which makes the atoms and molecules within the object move/vibrate faster and collide with each other. This kinetic energy energy comes from the temperature of the object being heated and is the thermal energy.
2. The atoms present in a hot object have higher kinetic energy when compared to a colder object and usually flow towards the colder object. This is why it is possible for the hot potato whose temperature is higher than the bowl of soup to flow towards the soup and from the soup to the surrounding room.
