Based on the given statement or reasoning above made by a student, what makes her reasoning incorrect is the part where she mentioned that "if they had not been built, she would not be exposed to radioactivity." This is definitely false. What makes this incorrect is that background radiation is a kind of radiation that is emitted by the sun, stars, and other bodies outside the universe and therefore, no one can escape from this. Hope this helps.

Differentiate between the factor(s) that affect inertia and momentum.
Oksanka [162]

Answer:

Inertia relates directly to an object's <em>mass</em>. It is its inherent property and expresses how much force is needed to bring the object to a certain level of acceleration. It is the sole factor.

Momentum relates proportionally to two factors: <em>mass</em> and <em>velocity</em>. As such, momentum is not an inherent property of an object but a measure dependent on it current velocity, in addition to its mass.

What is the momentum of a 3 kg bowling ball moving at 3 m/s?
nadezda [96]

Answer: 9kgm/s

Explanation:

Given that,

Mass of ball = 3 kg

Speed by which ball moves = 3 m/s. Linear momentum of the ball = ?

Since momentum refers to the quantity of motion of the moving ball,

Linear momentum = Mass x Speed

= 3kg x 3m/s

= 9 kgm/s

Thus, the linear momentum of the ball is 9kgm/s
