Chemistry for Biologists: Some basic chemistry
Some basic chemistry
Living organisms and chemistry
Biology is about living things - organisms. All living organisms are made of chemicals. To understand biological substances and the changes that take place in living organisms you need a good knowledge of the underlying chemistry. We will build up a picture of the chemicals that make up living organisms by starting small and getting bigger.
The starting point is atoms - the building blocks of all matter. We will then look at how these come together to make elements and compounds.
Answer:
The centripetal force acting on the car is proportional to the mass of the car.
Explanation:
Let,
The mass of the car be 'm'
The velocity of the car moving in the curved path be 'v'
The radius of the curved path be 'r'
According to physics, a body moving ion circular path experience a force directed along the radius of the path. This force is called centripetal force.
The formula for centripetal force is,
<em>F = mv²/r</em>
Where,
a = v²/r
So, if the mass of the car changes, the centripetal force also changes proportionally according to the above equation.
Answer:
it snaps
Explanation:
the more force you put on it, the wired out it gets than it snaps. I think
Answer:
B. an action-reaction force pair
Answer:
A: 0.83 Hz
Explanation:
Frequency can be calculated in a multitude of ways. The one way that is going to help you solve this problem is (# of times/seconds)
so you would divide 85 swings/102 seconds
= 5/6 or 0.8333 Hz
so your answer is A
