The electron sea model shows that electrons move freely among atoms (delocalized).
Metals are made up of atoms which has an array of positive ions in a sea of electrons.
The electrons can move freely within metal by detaching itself from its parent atom. Hence the electrons are said to be delocalized.
The electron sea model shows electrons on the surface of a metal being able to move freely from one atom to another.

if you slide down a rope, it's possible to create enough thermal energy to burn your hands or your legs where they grip the rope. suppose a 40kg child slides down a rope at a playground, descending 2.0m at a constant speed. how much thermal energy is created as she slides down the rope? assume that all potential energy can be transformed into thermal energy.
Answer:
Given,
mass, m=40kg
length of rope, h=2m
Required,
Thermal energy.
Assumption;
The P.E can be transformed to thermal energy.
then,
P. E = Thermal energy.
Since,
P.E = mhg
Thermal energy = mhg
T.E = 40*2*9.8
T. E = 784J
Therefore the thermal energy created will be 784J.

How would you choose to reduce the system shown to a 2 × 2? Explain why you would choose this approach. –3x y – 2z = 10 (1) 5x – 2y – 2z = 12 (2) x – y z = 23 (3)
Answer:
Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2). Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).
Explanation:
a canoe can be paddled at 7 mph through a placid lake the stream flows at 3 mph
Using system of linear equations the distance at the fisherman and the bobbler meets ls 8 miles
Speed in still waters = 7 mph
Stream speed = 3 mph
Upstream speed of canoe = 7 - 3 = 4 mph
Distance between fisherman and bobbler = 14 miles
Let seperation distance = d
Meeting distance = 14 - d
using the relation :
Distance= (speed × time)
canoe distance , d = 4t - - - - (1)
Noobler distance = 14 - d = 3t ----(2)
Equate (1) and (2)
d/4 = (14 - d)/3
3d = 4 (14 - d)
3d = 56 - 4d
7d = 56
d = 8 miles
Hence, the distance is 8 miles

the time take for the fisherman to meet the bobber is 2 hours
as given in the question ,
canoe being paddled at 7mph (at still water)
speed of the stream is 3mph
distance between the fisherman and the bobber is 14 miles
let the bobber and the canoe meet at a distance X
from the starting point of canoe.
then the distance of the meeting point from the fisherman is = (14 - X)
using the formula Distance = Speed x Time,
we have for the canoe,
D= 4T, ----- (1)
for the bobber, 14 - X = 3T ----- (2) ( speed of bobber = speed of stream= 3 MPH)
T is same in both equations, hence
=> [tex]\frac{X}{4} =\frac{14-X}{3}\\[/tex]

Based on the given matrix equation, the value of x and y are ±6 and 16 respectively.
How to determine the value of x and y.In order to solve for the value of x and y, we would create an equation from the upper and lower part of this matrix respectively.
x² - 4 = 32 ...........(upper part)
y + y - 4 = y + 6 ....(lower part)
Next, we would solve for x:
x² - 4 = 32
x² = 32 + 4
x² = 36
x = ±√36
x = ±6.
For the value of y, we have:
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 10
y = 16.

refer to the accompanying data set of mean drive-through service times at dinner in seconds at two fast food restaurants. construct a % confidence interval estimate of the mean drive-through service time for restaurant x at dinner; then do the same for restaurant y. compare the results.
Step-by-step explanation:
Assuming the data is as shown, restaurant X has a mean service time of 180.56, with a standard deviation of 62.6.
The standard error is SE = s/√n = 62.6/√50 = 8.85.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
180.56 ± 1.960 × 8.85
180.56 ± 17.35
(163, 198)
Restaurant Y has a mean service time of 152.96, with a standard deviation of 49.2.
The standard error is SE = s/√n = 49.2/√50 = 6.96.
At 95% confidence, the critical value is z = 1.960.
Therefore, the confidence interval is:
152.96 ± 1.960 × 6.96
152.96 ± 13.64

The immediate result after DNA replication are one old strand that came back together after replication and one completely new strand that was just assembled two completely new strands of DNA three strands of DNA, one old and two new two strands of DNA that each contain one strand of the original DNA molecule
Answer:
Two complete new strands of DNA / B
Explanation:
The immediate result after DNA replication is the synthesis of two strands out of which one old strand came back together after replication and one completely new strand was just assembled.
What is DNA replication?DNA replication may be characterized as a type of biological process through which a copy of the DNA in a cell is made before the cell divides. It is the process of producing two identical replicas of DNA from one original DNA molecule.
DNA replication is the process of copying and duplicating a DNA molecule. The process is carried out in a semiconservative way. This means that the new DNA molecule will consist of two strands: one that is newly created and the other is the original strand. DNA makes multiple copies of itself. It is a biological polymerization, which proceeds in the sequence of initiation, elongation, and termination.
Therefore, the synthesis of two strands out of which one old strand came back together after replication and one completely new strand was just assembled is the immediate result after DNA replication.
