Answer:
Part a)
Part b)
Part c)
As per Newton's III law force due to trailer on the car is same as that of force due to car on trailer.
Explanation:
As we know that
mass of car = 1120 kg
mass of trailer = 290 kg
acceleration of both
Part a)
Net force on the car
Part b)
Net force on the trailer is given as
Part c)
Force applied by car on the trailer is given as
so as per Newton's III law force due to trailer on the car is same as that of force due to car on trailer.
Weight gain I believe mark me brainlest
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.
The answer that best completes the statement above is COST-EFFECTIVE ANALYSIS. Occasionally, DUI checkpoints, also known as sobriety checkpoints are being established by police on the roadsides for safety purposes. This is also the same with the seatbelt laws. Both of these aim in decreasing motor-vehicular accidents. Comparing these two, we call it cost-effective analysis. When we say cost-effective, the effectivity of the action if being assessed in relation to the cost it takes to enforce the rule.
Answer:
mass=weight/gravitational acceleration
mass=1.059/10=105.9
