Y-STR analysis. It is a DNA test used to compute and match with the possibility via lap.
Acceleration is equal to the change in velocity per unit time. In this case, velocity has changed from 17.7 m/s to 14.1 m/s, which is a decrease of 3.6 m/s. This takes place in 12 seconds, so the average acceleration is 3.6 m/s / 12s = 0.3 m/s^2. The direction of this acceleration is south, since the car's northbound speed is decreasing.
I think it’s A I’m not too sure sorry if I’m wrong
Answer:
T=9.4 N
Explanation:
We are given that
Mass of wire,m=16.5 g=
kg
1 kg=1000g
Length of wire,l=75 cm=
m
1 m=100 cm
Wavelength of transverse wave=
m
Frequency=
Mass per unit length=
Where
frequency of wave
=Wavelength of wave
Speed of wave=v
Using the formula
Using the formula
Hence, the tension,T=9.4 N
HUMAN ACTIVITIES ARE threatening the health of the world's oceans. More than 80 percent of marine pollution comes from land-based activities. From coral bleaching to sea level rise, entire marine ecosystems are rapidly changing.
Global warming is causing sea levels to rise, threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish. Factories and industrial plants discharge sewage and other runoff into the oceans. Oil spills pollute the oceans, though U.S. water-sewage treatment plants discharge twice as much oil each year as tanker spills. Air pollution is responsible for almost one-third of the toxic contaminants and nutrients that enter coastal areas and oceans. The United Nations Food and Agriculture Organization estimates that 31.4 percent of fish stocks are either fished to capacity or over-fished.
