To convert 288 K to degrees Celsius, subtract 273.15 from the Kelvin temperature. Using this method, 288 K is equivalent to 14.85°C.
Explanation:The question requires converting the temperature from Kelvin to degrees Celsius. To convert temperature from Kelvin (K) to degrees Celsius (°C), you subtract 273.15 from the Kelvin temperature. The formula used is T°C = K - 273.15.
Given the temperature is 288 K, using the formula we get:
T°C = 288 K - 273.15 = 14.85°C
Therefore, the temperature of 288 Kelvin converts to 14.85°C in degrees Celsius.

What is the acceleration of a body revolving in a circle at uniform speed?
Answer: The correct answer is [tex]a=\omega ^{2}r[/tex].
Explanation:
In the circular motion, the speed of the body is uniform but the velocity of the body changes as the direction of the body changes in the circular motion. In the circular motion, there is only centripetal acceleration.
The acceleration of a body revolving in a circle is as follows;
[tex]a=\omega ^{2}r[/tex]
Here, [tex]\omega[/tex] is the angular velocity and r is the radius.
The direction of the centripetal acceleration is directed towards the center of the circle.
Therefore, the acceleration of a body revolving in a circle at uniform speed is [tex]a=\omega ^{2}r[/tex].
Which of these is a process by which water, carbon dioxide, and energy are formed? Which of these is a process by which water, carbon dioxide, and energy are formed? A) heating of sugar B) dissolving of sugar C) oxygen reacting with sugar D) hydrogen reacting with sugar
Answer:
C) oxygen reacting with sugar (usatestprep)
Explanation:
Oxygen reacting with sugar during the process of respiration produces water, carbon dioxide, and energy.
Oxygen reacting with sugar is a process by which water, carbon dioxide, and energy are formed, therefore the correct answer is option C.
What is solar energy?The energy emitted by the Sun as a form of thermal electromagnetic radiation is known as solar energy. This solar energy is produced by nuclear fusion in the center of the Sun. Solar energy is a form of renewable source of energy.
Thus, Oxygen reacting with sugar is a process by which water, carbon dioxide, and energy are formed, it is a type of exothermic reaction in which excess energy is produced on the product side, therefore the correct answer is option C.
