An inherited trait are features of an organism that can be passed down to one's offspring, for example eye color, hair color shape of the nose etc. They can be passed from generation to the next generation
Answer:
False
Explanation:
A Larger pulse with more energy means that the wave has a large amplitude. As in the given question, both the waves are travelling in the same medium, hence their speeds will remain the same and therefore the larger pulse will not overtake the smaller pulse. Remember the amplitude of a wave does not affect the speed at which the wave travels.
Answer:
The angle is
Explanation:
From the question we are told that
The mass is
The radius is
The speed is
According to the law of energy conservation
The potential energy of the mass at the top is equal to the kinetic energy at the bottom i.e
=>
Here h is the vertical distance traveled by the mass which is also mathematically represented as
So
substituting values
Speed =distance /time
0.75=30/time
Time=30/0.75=40mins
Answer:
This ability of charged particles to do work is called an electric potential.
Explanation:
When two negative charges are brought close to each other, they also repel. But when a positive and a negative charge are brought close together, they attract each other. When these two opposite charges are combined, they can be used to work. This is why we need a positive (+) and a negative (–) to light a bulb or run any electrical tool, equipment, mobile phone or home appliance.
