In this graph, the displacement of the particle in the last two seconds is 2 meters.
A positively charged particle made up of two protons and two neutrons and released by a radioactive nucleus is the alpha particle. ... 4) The process in which the nuclei of unstable atoms can become more stable by emitting particles and/or electromagnetic radiation is called radioactive decay.
Answer:
First Order Neurons
Explanation:
First Order Neurons
The main function of First Order Neurons is to deliver sensory information from sensory receptors to the spinal cord.
In Actual there are three orders of neurons, the first order neuron carry signals from periphery to the spinal chord, the second order neuron carry signal from from spinal chord to the thalamus. And the third order neurons carry signals to the primary sensory cortex.
Answer:
97 minutes and 12 seconds
Explanation:
Let x be the total time
From the first statement
Total time of Dara's exercise is 14580 seconds
40 %
Time when she had completed 40% was 1 hour 37 minutes and 12 seconds
The plastic strip becomes positively charged is because A) the plastic strip acquired extra protons during the charging process from the cotton. So, correct option is A.
Every object is made up of equal number of electrons and protons. Since charges are neutral because of equality, that is the reason behind every object is stable in this universe.
On rubbing with cotton cloth, a plastic strip acquired positive charge. Since, plastic strip is composed of electrons and cotton cloth is composed of positive protons. When we rubbed both of objects, because of opposite charge both of the charges cancelled each other.
Now, only positive charge of plastic strip remains and positive charge of cotton cloth remains. So, we know very well that like charges repel each other.
Therefore, at last plastic strips contains only positive charge and that is the reason of becoming positively charged after rubbing.
Hence, correct option is A.
