Shell is considered to be biotic because it has life, it is a living thing.
The temperature scale used in science is the Kelvin scale. The correct option among all the options given in the question is option "a". This is the standard scale used for measuring in astronomical and thermodynamics fields. The other scales can create complications as different countries use different type of scales.
Answer:
If the same force is applied to an object with a large mass it will have a <u>smaller (lesser) </u>acceleration
Explanation:
force and mass are inversely proportional. force and acceleration are directly proportional. which means greater mass have smaller acceleration and smaller mass has greater acceleration. this is due to newtons second law of motion.

Explanation:
The scanner records the time from when a ultrasound wave is emitted to when its reflection is received. A technician calculates the depth of the reflection using the equation as :
The distance covered by ultrasonic wave when it was emitted and gets reflected is 2d. Speed is given by :
d is distance and t is time
Here, d = 2d
So, the factor of (1/2) is used because the distance covered by the wave is 2 times when it was emitted and received.
