24. A car has a mass of 2,000 kg and speeds up at a rate of 2 m/s? What is the net
force exerted on the car?

Force exerted on the car = 4,000 N

Explanation:

Mass of the car (m) = 2000 kg

Acceleration(a)  = 2 m/sec²

By Newton's second law of motion,

F (force)  = m a

Putting the values of m and a

    = 2000 x 2 = 4,000 N

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
