All of the answers apply because any object can have positive, negative or neutral charges depending on their atoms
Neutron stars are the most dense stars
Answer:
0.03 s
Explanation:
The maximum force is 90 N, and the mass is 0.2 kg, so we can find the deceleration:
F = ma
-90 N = (0.2 kg) a
a = -450 m/s²
The initial velocity is 14 m/s, and the final velocity is 0 m/s, so the time is:
v = at + v₀
0 m/s = (-450 m/s²) t + 14 m/s
t = 0.03 s
The fastest she can slow it down to a stop without breaking it is in 0.03 s.
Answer:
The seismic refraction is a geophysical principle governed by Snell's Law. Used in fields of engineering geology geotechnical engineering and exploration geophysics, seismic refraction traverses are performed using a seismograph or geophone in an array and an energy source

Answer:</h2>
Deductive reasoning
<h2>
Explanation:</h2>
The process of using pre-existing knowledge to make logical conclusions, make predictions and draw out explanations is called reasoning. Reasoning are basically of two types:
i. Deductive reasoning: This takes a general rule, idea, or theory as foundation and then proceeds from there to draw meaningful conclusions or predictions. For example;
<em> If a = 3 ----------------(i)</em>
<em> And b = 5 ----------------(ii)</em>
<em> Then 2a + 4b = 26 -------------(iii)</em>
From above, following from equations (i) and (ii), it can be concluded that (iii) should be true.
ii. Inductive reasoning: While deductive reasoning moves from a general rule to specific rule, inductive reasoning does the opposite - moves from specific to a general rule.
