So for D you have to find energy right
from c you get wavelength Lambda
so on D use this
E = Hc / lambda
c is given 1.5 x 10 ^20
h = 6.624 x 10^-34
and then you get answer for energy
Answer:
100Jkg/°C
Explanation:
Given parameters:
Mass of metal = 2kg
Amount of heat energy = 1600J
Initial temperature = 5°C
Final temperature = 13°C
Unknown:
Specific heat capacity of the metal = ?
Solution:
Specific heat capacity of a body is the amount of heat needed to raise the temperature of unit mass of a body by 1°C.
H = m x C x (T₂ - T₁ )
H is the amount of heat
m is the mass
C is the unknown specific heat capacity
T is the temperature
Insert the parameters and solve;
1600 = 2 x C x (13 - 5)
1600 = 16C
C = 100Jkg/°C
- Dalton reported that seven pounds of Oxygen reacted with one pound of hydrogen to form water, but accurate modern experiment gives eight pounds to one.
- Lavoisier reported that water contains Oxygen 5.6 times more than hydrogen by weight.
- Dalton assumed that water contains 1 atom of oxygen and 1 atom of hydrogen and concluded that the relative weight of O must be 5.6 times as large as the H atom.
- By determining the relative mass we will be able to determine for example that one element has twice the mass of a second element.
Psoas major muscles, kidneys, inferior ribs, and lumbar transverse processes are demonstrated on AP abdominal projections.
<h3>What are AP abdominal projections?</h3>
The anteroposterior (AP) radiograph the patient in a supine position is the basis of the majority of plain-film examinations of the abdomen.
However, an upright-position film could also be helpful in patients with suspected bowel obstruction, also as to assess the air-fluid levels in the distended bowel.
This information also can be obtained on a film of the abdomen taken with the patient in the lateral decubitus position.
An AP supine projection is usually called a flat plate or KUB (because it includes the kidneys, ureter, and bladder)

idek what that is but i have the question on my homework rn
