Answer:
Often loose fibers surrounding a contact hole show scorch marks from the flame discharge of the weapon. Some synthetic fibers may be melted. The blowback of muzzle gases may produce a star shaped tear pattern around the hole.
Explanation:
The magnitude of electric field is produced by the electrons at a certain distance.
E = kQ/r²
where:
E = electric field produced
Q = charge
r = distance
k = Coulomb Law constant 9 x10^9<span> N. m</span>2<span> / C</span><span>2
Given are the following:
Q = </span><span>1.602 × 10^–19 C
</span><span>r = 38 x 10^-9 m
Substitue the given:
E = </span>
E = 998.476 kN/C
Answer:
When the y-coordinate is 12m, the x-coordinate of the particle is 24 m
Explanation:
Given;
y - component of acceleration = 1 m/s²
X - component of acceleration = 2 m/s²
distance traveled in y - direction, Dy = 12 m
To determine the distance traveled in X- direction, we obtain the duration of the displacement in y- direction.
Applying equation of motion;
Dy = ¹/₂ x at²
For distance traveled in x -direction;
Dx = ¹/₂ x at²
Dx = ¹/₂ x 2 x (4.9)² = 24.01 m ≅ 24m
Therefore, when the y-coordinate is 12m, the x-coordinate of the particle is 24 m
