c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.
Explanation:
We can answer this question by using Newton's second law of motion, which states that the net force applied on an object is equal to the product between the mass of the object and its acceleration. Mathematically:
where
F is the net force
m is the mass of the object
a is its acceleration
From the equation, we notice that:
- The force is directly proportional to the mass of the object --> so if the mass increases, the force needed to accelerate the object will increase too
Therefore, the correct answer is
c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.

Answer:
a. 8000 N/C or 8000 V/m
b. Incomplete question
Explanation:
a. The electric field, E, is the ratio of the potential difference,V, to the separation distance, d.
V = 360 V
d = 45 mm = 0.045 m
b. The force on a charge in an electric field is the product of the field and the charge.
With the charge, q, known, the force can be calculated.
At angular speed of 3 rev/s, the object moves a distance equal to 3 times the circumference of the circle each second, or a distance of 3 • 2<em>π</em> (1.20 cm) ≈ 22.6 cm.
So, with a linear speed of 22.6 cm/s = 0.226 m/s, the object has a centripetal acceleration <em>a</em> of
<em>a</em> = (0.226 m/s)² / (0.012 m) ≈ 18.8 m/s²
directed toward the center of the circle.
The answer is the universe. It can be defined as everything that
exists, everything that has occurred, and everything that will exist. It
is also all of space and time and its
contents which comprises of moons, planets<span>, minor
planets, stars, galaxies, the contents of intergalactic space and all matter<span> and forms
of energy (including electromagnetic radiation and matter), and
the physical laws that relate them. The Universe covers
all of life, all of history, and some theorists and scientists recommend that
it even encompasses notions such as logic and mathematics.</span></span>
