Answer: B (Longitudinal waves travel through solids, liquids, and gases, Transverse waves only travel through solids)
Explanation: A longitudinal wave alternately compresses the medium and stretches it out. Solids, liquids and gasses all push back when they are compressed— so they are all able to store energy this way and thus transmit the wave. But, Transverse waves can only go through solids because they have enough shear strength, but liquids and gases don't. ( Transverse waves are the transfer of energy in a motion that is perpendicular to the direction the wave is traveling. Only solids are able to switch it's motion to travel through the wave.)
Answer:
Explanation:
Reasons for a high/low rate of Mortality: Science can be very invaluable determining the high/low rate of mortality in an area by conducting extensive research on various factors the people (of a society) are exposed to that causes the rate of mortality. In the case of high-rate of mortality, science can assist in providing guidelines in reducing the rate.
Epidemiology and Treatment of diseases: If there is a rise in the number of people affected by a particular disease in a society, science can help provide answers by determining if indeed the diseases are the same or just appear the same. Science can also assist in preventing and providing cure (treatment) to this disease.
Optimization and improved nutritive diet: Science assists in optimizing food products in order to get maximum benefits from the food eaten. A society might have some food substances that are not well stored or processed before eating; which could lead to loss of important nutrients, science can help correct this societal norm through research.
Because he found that electrons are negatively charged particles, seperate from the positively charged nucleus, although his model was still incorrect
The resultant force will be equal to difference of her downward force, her weight, and the upward force, the air resistance.
Fnet = 657 - 51.1 x 9.81
= 149.7 N
F = ma
a = F / m
a = 149.7/51.1
a = 2.93 m/s²
