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.

Acceleration = v2 - v1 / t
a = 80 - 40 / 2
a = 40 / 2
a = 20 m/s²
In short, Your Answer would be 20 m/s²
Hope this helps!
The right answer for the question that is being asked and shown above is that: "B) Earth's temperature has not changed over time." Scientists have observed that the average sunspots have increased in the last 50 years. The statement that best describes an effect of this increase in sunspots <span>Earth's temperature has not changed over time. </span>
Answer:
84 meters
Explanation:
Using these two kinematic equations : Vf= Vi +at and
D= [(Vi+Vf)/2]*t
Plugging in what we know into the first equation to solve for the Final velocity, you'll get Vf= 2 m/s + 4(m/s^2)*6s = 26m/s
plug time vi and vf into the second equation to solve for displacement.
Given:
The mass of the truck is m1 = 3162 kg
The speed of the truck is v1i = 12 m/s in East
The mass of the parked car is m2 = 510 kg
The speed of car is v2i = 0 m/s
The speed of car after collision is v2f = 24 m/s in East
To find the speed of the truck after collision.
Explanation:
The final velocity of the truck will be

Thus, the speed of the truck after collision is 8.129 m/s
