Answer:

an article on the beneficial bacteria in yogurt, featured in Medical Journal of Gastroenterology

Explanation:

This article is published in a Medical Journal, which means the contents must be credible, informative, and accurate. In order to be these things, the author most likely had others review their writing to remain objective and ensure quality work. The other articles are not meant to solely inform and are featured in less credible magazines. Therefore, the third option is correct.

how does the total mass of each object increases the amount of force that is needed to get them moving at 5 m/s increase by abou
irakobra [83]

Answer:

The answer is below

Explanation:

Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum with respect to time, going in the same direction as the force.

Let F = force, m = mass of object, v = velocity of object, mv = momentum.

F = d/dt(mv) = m(dv / dt) = ma; a = acceleration.

Let us assume that the object starts from rest to 5 m/s within 1 seconds, hence:

F = m(dv / dt)

200 N = m[(5 m/s - 0 m/s) / (1 s)]

200 = 5m

m = 40 kg
