When placed near a second charge, a 60-μC charge experiences a force of 0.30 N. What is the electric field strength at the locat

jeka57 [31]

Answer:

$E=5000N/C$

Step-by-step explanation:

From the question we are told that

Charge $q= 60 \mu C$

Force $F_=0.30N$

Generally the equation for electric field strength is mathematically given as

$E=F/q$

$E=\frac{0.30}{60*10^-^6}$

Therefore

$E=5000N/C$

Cerrena [4.2K]

Length of bar= 6 units
Width of bar= 13 units
Formula for area of rectangular chocolate bar:
A= L x W
Put values
A= 6 x 13
A=78 square units
So he will break the bar into 78-1=77 times

Answer: 77 times

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your

Mila [183]

The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.

<h3>What are the critical values of r?</h3>

Question Parameters

r = -0.868

n = 5

df = 5 - 2

df = 3

$\alpha / 2 =0.025$

Critical values $r= \pm 0.878$

Generally, there exists no linear correlation between the Critical values

as r=0.878

In conclusion, Critical values: r = +0.487, no significant linear correlation
