Answer:
Decreasing the use of fossil fuels will improve the wellbeing of animals (and people, for that matter). Burning fossil fuels like coal and using oil and other limited resources has polluted the biosphere, and this has had an adverse impact on many animals. If we were to limit this, it would no doubt improve their situation and make them less likely to extinction.
Answer:
weight on Venus = 604.15 N
weight on Venus = 252.01 N
Explanation:
Given:
Weight on the earth , W = 150 lbs
now,
1 lbs = 4.45 N
thus,
W = 150 × 4.45 = 667.5 N
now, mass on the earth, m = 667.5/9.8 = 68.11 kg
now,
⇒ weight on Venus,
the acceleration due to gravity on venus = 8.87 m/s²
thus,
weight on Venus = mass × acceleration due to gravity on venus
or
weight on Venus = 68.11 × 8.87 = 604.15 N
⇒ weight on mars,
the acceleration due to gravity on mars = 3.70 m/s²
thus,
weight on Venus = mass × acceleration due to gravity on venus
or
weight on Venus = 68.11 × 3.70 = 252.01 N
After the great 1906 San Francisco earthquake, geolophysicistHarry Fielding Reid examined the displacement of the ground surface along the San Andreas Fault. He concluded that the quake must have been the result of the elastic reboundof the strain energy in the rocks on either side of the fault.
strain energy is 0. 5x force x (compression) X (compression)
There is a lot of force and a bit of compression when rocks squash up against other rocks causing earthquakes
Explanation:
Force is defined as mass times acceleration.
Mathematically, F = m × a
where F = force
m = mass
a = acceleration
This shows that force is directly proportional to acceleration. So, when greater force is applied then acceleration will also increase.
Whereas acceleration is inversely proportional to mass. So, when there is increase in mass then there will be decrease in acceleration.
Answer:
An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.
Explanation:
This organisation of genes is normally present in bacteria. For example, genes involved in lactose metabolism are clustered in the lac operon of E. coli, and genes involved in tryptophan metabolism are in the trp operon.
