Answer:
Masa, m = 0.088 kg
Explanation:
Given the following data;
Temperatura inicial = 30°C
Temperatura final = 120°C
Capacidad calorífica específica = 138J/kg.K
Calor absorbido, Q = 4400 cal.
Para encontrar la masa;
La capacidad calorífica viene dada por la fórmula;
Dónde;
Q representa la capacidad calorífica o la cantidad de calor.
m representa la masa de un objeto.
c representa la capacidad calorífica específica del agua.
dt representa el cambio de temperatura.
dt = T2 - T1
dt = 120 - 30
dt = 90°C to kelvin = 273 + 90 = 363K
Sustituyendo en la fórmula, tenemos;
Masa, m = 0.088 kg
Answer:
-There are no other charges nearby.
Explanation:
-There are no other charges nearby.
If there is no net charge in nearby space then the force on this charge will be ZERO
-If there are other charges nearby, they must all have the same sign as Q.
There there is nearby charge of same sign then it will have repulsion force on Q
-If there are other charges nearby, they must all have the opposite sign of Q.
if there is nearby charge of opposite sign then the force must be attraction force.
-If there are other charges nearby, the total positive charge must equal the total negative charge.
If there exist two type of charges nearby then there may exist either attraction or repulsion force on it
Answer:
the first questions answer is- the pressure is the same (balanced) outside and inside the window.
the second questions answer is- the atmospheric pressure increases.

Answer:
<h3>When two objects collide, in the absence of any additional external forces acting on the pair of objects, momentum is conserved precisely because the collision is just an interaction between the two objects. That is, it's a Newton's third law problem.</h3>
The shortest wavelength in the paschen series= 
m.
<h3>How do we calculate the shortest wavelength in the paschen series?</h3>
Emission lines for hydrogen occur when electrons drop from some energy level to a lower energy level. To calculate the shortest wavelength in the paschen series we are using the formula,
Here, we are given,
= Rydberg constant=
= The lower energy level quantum number.=3 (for the paschen series).
n= The quantum number of whichever state the transitions occur from = (for this case of the paschen series).
We have to find the wavelength associated with the photon emitted = 
m.
Now we substitute the known values in the above equation, we can find that,
Or,
Or,
Or,
m
From the above calculation we can conclude that the shortest wavelength in the paschen series is m
