Answer:

B. 5.9 X 10^9

Explanation:

For this question, we assume the following:

•2.3 x 1014 inches is actually 2.3 x 10^14 inches.

•3.9 x 104inches is actually 3.9 x 10^4inches

We now calculate thus;

The average distance in km would be 2.3 x 10^14/3.9 x 10^4

= 0.59 X 10^10.

Therefore, we have;

5.9 X 10^9km.

A horizontal spring with spring constant 950 N/m is attached to a wall. An athlete presses against the free end of the spring, c
OLga [1]

Answer:

66.5N

Explanation:

F = kx

Where F = force

K = spring constant

x = compression

Given

K = 950N/m

x = 7.0cm

F = ?

First convert the compression to meters .

7.0cm = 7.0 x 0.01

= 0.07 meters

Therefore

F = 950 x 0.07

= 66.5N

Linda is a forensic scientist arriving at the crime scene. What must she do before she can examine the crime scene?
Bezzdna [24]

Answer:

In the more scientific viewpoint, the most important thing that she must do is caring for her hygiene and put some plastic gloves in her hands.

This is because there are lots of particles that can be retained in the hands (dust, skin, etc), and when examining the scene, she may drop some of these particles, "contaminating" the scene in this way with information that only will affect the investigation.

So the most important thing is being prepared to not affect anything in the crime scene

S Five particles with equal negative charges -q are placed symmetrically around a circle of radius R. Calculate the electric pot
Scrat [10]

The four distinct charges' combined potentials make up the potential in the square's center. The amount of the charge and the distance from the charge both affect the potential caused by a point charge.

Therefore, the center's total potential is V=4V1=ks4 q.

<h3>What is a charge?</h3>

Due to the physical characteristic of electric charge, charged material experiences a force when it is exposed to an electromagnetic field. An object that has no net charge is said to be neutral. Classical electrodynamics is the name given to an earlier theory of the interactions of charged particles.

You can have positive or negative electric charges (commonly carried by protons and electrons respectively). opposing charges attract one another whereas similar charges repel one another.
