Answer:
Maximum speed of the coin, v = 0.607 m/s
Explanation:
It is given that,
A coin rests on a record 0.13 m from its center i.e. the radius of the circular path, r = 0.13 m
The coefficient of static friction between the coin and the record is, 
The centripetal force acting on the coin is balanced by the frictional force. Its mathematical relation is given by :
v = 0.607 m/s
So, the maximum coin speed at which it does not slip is 0.607 m/s. Hence, this is the required solution.
Answer and explanation;
According to twin studies attitudes may be genetically based, research has supported that Identical twins are more likely to share similar attitudes. Attitudes change as the result of behavior and not the other way around
Genetic factors may influence general dispositions and condition-ability that may influence formation of more specific attitudes. Controlled twin studies in US and Sweden reveal that identical twins share more similar attitudes than fraternal twins.
Answer:
<h2>5 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
We have
We have the final answer as
<h3>5 m/s²</h3>
Hope this helps you
Answer:
The statement "If a positively charged rod is brought close to a positively charged object, the two objects will repel
" applies to electric charges.
Explanation:
There are only two types of electric charges. Both having own magnitude but different charge.
1. Positive charge
2. Negative charge
Like charges repel each other and opposite charges always attract each other.
When a positively charged rod is brought close to a positively charged object, the rod and the object will repel.
Answer:
In physical changes no new materials are formed and the particles do not change apart from gaining or losing energy. ... Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. Only their arrangement, energy and movement changes.
Explanation:
this is true because if you think about it if you put a pill in a glass of water it dissolves its like particles
