Answer:
b
Explanation:
b. increased frequency and severity of forest fires
Because of the Global warming the forest fires have increased drastically. The recent fire in Amazon rain forest is an example of this. These burning forests emit a large amount of CO2 yet again and further causing more global warming. According a a recent data it is estimated that forest fire emit about 8 million tons of CO2 in the atmosphere in last 20 years. In,2017 total global CO2 emission has reached to 32.5 billion tons, according to IEA.

Answer:

b)False
c)False
• Had to complete the question first.
A block slides at constant speed down a ramp while acted on by three forces: its weight, the normal force, and kinetic friction. Respond to each statement, true or false.
(a) The combined net work done by all three forces on the block equals zero.
(b) Each force does zero work on the block as it slides.
(c) Each force does negative work on the block as it slides.
Explanation:
Net work is the change in kinetic energy, which leads to final kinetic energy - our initial kinetic energy this is the formula for net work. This is the working energy theorem, a theorem that states that the net work on an object induces a change in the object's kinetic energy.
