KonstantinChe [14]3 years ago

Answer:

The Machine exerts a force of 9N.

Explanation:

Initial velocity (u) = 0 m/s

Final velocity (v) = 30 m/s

Time (t) = 0.5 s

Acceleration (a) = (v-u)/t

= (30-0)/0.5 m/s²

= 30/0.5 m/s²

= 60 m/s²

Mass = 0.15 kg

Force = Mass*Acceleration

= 0.15*60 N

= 9 N

The Supreme Court's power would be diminished if they give advisory opinions. Courts are designed to objectively look at situations that are happening between parties. If they input their opinion in a particular decision, then they would have become biased and ruled out their objectivity. In able for them to become in control, they need to always watch from the sidelines and then decide afterwards.

What type of forces do not change the motion of an object?
STALIN [3.7K]
Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.

anzhelika [568]

Physical distance is the correct answer.

Studies have shown that having a close relationship between grandparents and grandchildren is important and can reduce symptoms of depression for both. However, more and more kids have grown up without having much physical or emotional contact with their grandparents. The most common explanation for grandparents and grandchildren to have a remote relationship is the physical distance between them.

Gnesinka [82]

Since Marbury, the Supreme Court has greatly expanded the power of judicial review. ... It is difficult to overstate the effect that Marbury and its progeny have had on the American legal system.
