Answer:
B) They are made up of particles that travel in a curved path when in motion.
Explanation:
We know that gas, being a state of matter, is made up of particles. John Dalton's solid-sphere model was proven to be incorrect by Ernest Rutherford's gold foil experiment.
These particles do NOT always move very slowly. There are multiple different factors that affect the speed of the particles such as temperature or concentration.
There are two terms
a) accuracy : it relates to the exactness of an answer that how an answer is close to the actual answer or actual reading
So 104.6 is accurate
b) Precision : This is related to the closeness of different readings with each other
The first reading is 103.7 and the second one is 108.4 so the second reading is quite different from the first reading so it cannot be called as precised
Again 105.8 has good difference from the second reading hence again this is not precised
However the last reading 104.6 is quite near to 105.8 so 104.6 can be called as precise
Answer:
D. Contracted Blood Vessels
Explanation:
The more constricted arterioles are, the greater their resistance to blood flow and the higher the blood pressure. Constriction of arterioles increases blood pressure because more pressure is needed to force blood through the narrower space. Conversely, dilation of arterioles reduces resistance to blood flow, thus reducing blood pressure.
If you start rubbing the balloon against the hair it causes electrons to move from the hair and since electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge.
