Answer:
Preoperational
Explanation:
According to Piaget's theory of cognitive development, the preoperational stage is the second stage. This stage includes children between the age group of 2 to 7 years. Children can understand conservation tasks and learn to manipulate various symbols during this stage.
So, the answer is the preoperational stage.
Answer:
a)
The analytic expression for p(V) is 
b)
The expression of the work in terms of p0 ,V0,V1 is
![W= \frac{5}{2} P_{0}[V_{0}-V_{0}^{7/5}V_{1}^{-2/5}]](https://tex.z-dn.net/?f=W%3D%20%5Cfrac%7B5%7D%7B2%7D%20P_%7B0%7D%5BV_%7B0%7D-V_%7B0%7D%5E%7B7%2F5%7DV_%7B1%7D%5E%7B-2%2F5%7D%5D)
c)
The change in internal energy of the gas
![\delta U = \frac{5}{2}P_{0}[V_{0}^{7/5}V_{1}^{-2/5}-V_{0}]](https://tex.z-dn.net/?f=%5Cdelta%20U%20%3D%20%5Cfrac%7B5%7D%7B2%7DP_%7B0%7D%5BV_%7B0%7D%5E%7B7%2F5%7DV_%7B1%7D%5E%7B-2%2F5%7D-V_%7B0%7D%5D)
Explanation:
The explanation is shown on the first, second and third
Answer:
force on the proton = 5.96 ×
N
Explanation:
given data
kinetic energy = 1.16 ×
eV
charge density of σ = +6.60 μC/m²
solution
we get here force on the proton that is express as
F = qE ....................1
here q is charge on proton i.e = 1.6 ×
C
and E is electric field due to charge i.e E =
so put the value in equation 1 we get
force on the proton = 1.6 ×
×
force on the proton = 5.96 ×
N
Answer
= 60
Hope it helps:)
Is there any numbers to your question?
