A straight, nonconducting plastic wire 8.00 cm long carries a charge density of 100 nC/m distributed uniformly along its length.
Sphinxa [80]

Answer:

(A) 16641 N/C (B) 72000 N/C

Explanation:

We have given the length of the wire = 8 cm =0.08 m

Charge density = 100 nC/m

So charge = 100 ×0.08 = 8 nC =8\times 10^{-9}C

(A) Electric field E that produce 6 cm directly above its midpoint will be

E=\frac{KQ}{X\sqrt{X^2+a^2}}=\frac{9\times 10^9\times 8\times 10^{-9}}{0.06\sqrt{0.06^2+(\frac{0.08}{2})^2}}=16641N/C

Here X is the distance where we have to find the electric field

(B) Now electric field due to flat ring will be

E=\frac{KQX}{(X^2+a^2)^\frac{3}{2}}

Here X is the distance where we have to find the electric field

So E=\frac{9\times 10^9\times 8\times 10^{-9}}{(0.06^2+0.08^2)^\frac{3}{2}}=72000N/C

Tritium and helium-3 have the same number of nucleons, but tritium has one proton and two neutrons whereas helium-3 has two prot
ryzh [129]

Answer:

Tritium is more stable.

This happens in part because the tritium nucleus has an extra neutron enhancing the nuclear forces.

Explanation:

The binding energy is the energy that holds nucleons together in the nucleus. It depends on the number of nucleons present in the nucleus. The greater the number of nucleons, the greater the binding energy.

Also, the more the number of neutrons in a nucleus, the greater the nuclear forces. Helium-3 has only one neutron while tritium has two neutrons. The extra neutron in tritium enhances the nuclear forces hence tritium has a greater binding energy than Helium-3

Be sure to show all 4 steps for each of the problems below.
Kisachek [45]

Answer:

1=920

2=2300

Explanation:

from the question,

M¹=23

H¹=4

g=10(constant)

using the formula

P. E,= mgh

P. E= 23×10×4=920

P. E=23×10×10=2300

Which researcher first realized that certain psychic secretions pointed to a simple but important form of learning
AnnZ [28]

Ivan Pavlov was the researcher that first realized that certain psychic secretions pointed to a simple but important form of learning.


The way he figured this out was when dogs paired certain things with food, and because of this, the dogs started salivating.
