Answer: 2.5\frac{m}{s^{2}}


According to Newton's 2nd Law of Motion (in the specific case when the mass m <u>is constant</u>) the acceleration a that a body acquires is directly proportional to the exerted force F on the body.

As shown in the following equation:


F=ma    (1)


We already know the value of the mass of the car and the force excerted on it. So, we need to find the value of the acceleration from equation (1):


a=\frac{F}{m}     (2)


And substitute the known values:


a=\frac{3000N}{1200kg}    


At this point, note that 1N=1kg\frac{m}{s^{2}}


Taking this into account, the acceleration of the car is:


a=2.5\frac{m}{s^{2}}

Which of the following is most negatively affected by fishing practices? a. deep sea corals b. ocean microbes c. methane hydrate
Sergio039 [100]

Answer:

Hi,

The correct answer option is a. deep sea corals

Explanation:

Deep sea corals are organism that habit the deeper and dark parts of the ocean and survive by feeding on tiny organisms washed by currents to obtain nutrients and energy.A major characteristics of these organisms is that they grow very slowly. Fishing practices such as dragging the sea floor with heavy fishing equipment and machines can destroy the homes of these organisms (coral gardens) thus affecting even the other organisms that live among them.

Best of Luck!
