Explanation:
Using the Newton's laws, we can find the force F required for lifting the book having mass (m) and acceleration due to gravity (g) that is ;
and, the change in the position of the book that is Δx (Height)
→ Δx = Final position - Initial position
which is only the height, then the amount of work done will be calculated by :
W= mgh
m = Mass of the Body
g = Acceleration due to Gravity
h = Height of Body being displaced
Answer:
Explanation:
From the given data on the table, I can easily say my weight is a function of the acceleration due to gravity at anywhere in the universe.
Weight is given as
W = mg
m is the mass and g is the acceleration due to gravity.
Weight for a mass of 65kg would be the heighest on the surface of jupiter and it would be lowest on merury and mars due to their low value of g.
Answer:
The conclusion is that the mass is independent of gravity. However, the weight depends on the gravity value.
Explanation:
We have a girl with a mass of 65 kg. The picture has the gravity value for different planets. Weight (W) of a body is the product between the mass (M) and the gravity (g).
W = M*g.
According to the information we can mention that the weight of the girl will vary in all the planets. The highest weight will be for the highest gravity value of Jupiter with 25.9 m/s2. The lowest weight will be for Mercury and Mars with a gravity value of 3.7 m/s2.
It is important to mention that the mass of the girl will be the same in all the planets. However, the weight will vary according to the gravity variations.
Finally, The conclusion is that the mass is independent of gravity. However, the weight depends on the gravity value.
determine if it was DNA or RNA?
Answer:
Nucleobases should be checked. RNA contains adenine, guanine, cytosine and uracil instead of thymine, so if we isolate uracil, it means that it is RNA, if not, then is DNA.
Answer:
The answer is Temperature (Heat), Pressure and chemical activity of fluids.
Explanation:
Metamorphic rocks result from the transformation of pre-existing rocks that have undergone structural and mineralogical changes under certain physical or chemical conditions such as temperature, pressure or chemical activity of the fluids. This type of modification is known as a process called metamorphism, in which igneous rocks or sedimentary rocks, when subjected to high temperatures, pressures or active fluids, cause changes in their composition, bringing new substances to them.
My number one tip is to STUDY! I know it sucks, but once you're in high school, it's going to become a part of your routine every single day. Even if you study right now, keep on doing it over and over and over. Trust me! It'll help. Also, get a tutor! Maybe someone you know is doing well and you could ask them to help, or you could ask a student who was in your class and passed. My number one advice is to just keep working hard. I get it; chemistry is HARD. You'll get there!
