Answer:
So three lowest possible values of d ar 0.85m, 2.55m and 4.25m
Explanation:
The wavelength of wave:
λ=v/f
λ=340/200=1.7m
The destructive interference condition is:
Δd=(m+1/2)λ where m=0,1,2,3........
For minimum destructive interference ,the value of m is equal to zero
Δd=(0+1/2)×1.7
Δd=0.85m
For m=1
Δd=(1+1/2)×1.7
Δd=2.55m
For m=2
Δd=(2+1/2)×1.7
Δd=4.25m
So three lowest possible values of d ar 0.85m, 2.55m and 4.25m
unlike magnetic strips, which store only account information, an E-pusre or e-wallet stores funds on an integrated circuit chip.
- A digital wallet is an app used to carry out financial transactions on mobile devices (or electronic wallet).our passwords and payment details are securely stored there. Instead of carrying our cards with us while shopping, these programs let us pay using our mobile. we input and save the details of our credit card, debit card, or bank account so that we may use our smartphone to make purchases later on.
- The purpose of digital wallets is to increase access to financial goods and services by utilizing the capabilities of mobile devices. Due to its ability to safely and conveniently store all of a user's payment information, digital wallets effectively do away with the need to carry a traditional wallet.

Answer:
El esfuerzo cortante, de corte, de cizalla o de cortadura es el esfuerzo interno o resultante de las tensiones paralelas a la sección transversal de un prisma mecánico como por ejemplo una viga o un pilar. Se designa variadamente como T, V o Q.
Este tipo de solicitación formado por tensiones paralelas está directamente asociado a la tensión cortante. Para una pieza prismática se relaciona con la tensión cortante mediante la relación:
(1){\displaystyle Q_{y}=\int _{\Sigma }\tau _{xy}\ dydz,\qquad Q_{z}=\int _{\Sigma }\tau _{xz}\ dydz,\qquad Q={\sqrt {Q_{y}^{2}+Q_{z}^{2}}}}
Para una viga recta para la que sea válida la teoría de Euler-Bernoulli se tiene la siguiente relación entre las componentes del esfuerzo cortante y el momento flector:
The answer is; The sun will turn into a red giant
This occurs as the hydrogen fuel in the fusion core of the sun begins to deplete. When the hydrogen fuel is depleted, the star begins to collapse on itself due to gravity. This pressure causes the heavier helium to begin fusing in the area around the core. The stars begin to heat up again producing enough energy to push out the outer shells of the star. This causes the star to expand. The outer shells become less hot hence the decrease in luminosity of red giants.
