Answer:
Burning Paper
Explanation:
This is a chemical reaction, because new substances are formed
Answer: 1
Explanation:
Given
Tension is the string 
mass of object 
Tension is greater than the weight of the object i.e. elevator is moving upward
we can write
Answer:
The tension in the string is equal to Ct
And the time t0 when the rension in the string is 27N is 3.6s.
Explanation:
An approach to solving this problem jnvolves looking at the whole system as one body by drawing an imaginary box around both bodies and taking summation of the forces. This gives F2 - F1 = Ct. This is only possible assuming the string is massless and does not stretch, that way transmitting the force applied across it undiminished.
So T = Ct
When T = 27N then t = T/C = 27/7.5 = 3.6s
Answer:
The ending pressure is R.
Explanation:
This is Recreational scuba diving (R). According to standards, this diving has prescribed depth limit of 130 ft. This means that the limit must include a depth that is not greater than 130 ft while using only compressed air and not even requiring a decompression stop.
Now, from the question, we can see that that there was a prescribed limit of 60ft of water with a planned bottom time of 30 minutes.
Thus, the ending pressure is R.
Making models
is a skill that involves creating a representation of complex objects or
processes. Through the years, people have been creating models in order to
make a clearer visualization and give reality to a certain object. Some
example of model making are toys like plastic cars as a model
representation of a real car, a plastic plane, model representation of a
real plane and a doll, a model representation of us, human. One of the
most famous model representation as of today is the film or movie making.
This represents the lives of the people and show stories about how people
face every challenge in life.
