Answer:
12
Explanation:
I am not sure this is a simple answer
In endothermic reaction heat was absorbed , so the reaction will absorb heat from water so the final temperature of water is less than initial temperature
Tf < Ti
Answer:
Carbon
Explanation:
The field of organic chemistry is the field of the study of the compounds of carbon mostly with hydrogen but they can contain the presence of other atoms such as oxygen, nitrogen, sulfur even metals such as lithium. It studies the structure, properties, synthesis and reactions of these compounds. The field of organic chemistry is the field of living organisms as they are mostly are formed by organic compounds hence its name organic.
Answer:
At the maximum height of the vault
Explanation:
The formula for gravitational energy (GPE) is
GPE = mgh, where
m = the pole vaulter's mass
g = the acceleration due to gravity
h = the height above the ground
Since m and g are constant,
GPE ∝ h
The point of highest GPE is at the maximum height of the vault, just before he starts falling towards the ground.
Answer:
A.
The sound is transmitted through water until it reaches the other whale.
Explanation:
When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.
