The density of atmosphere (measured in kilograms/meter3) on a certain planet is found to decrease as altitude increases (as meas

ured from the planet's surface). What type of relationship exists between the altitude and the atmospheric density, and what would the atmospheric density be at an altitude of 1,291 kilometers?

I know that the relationship between altitude and atmospheric density is that the higher the altitude, the lesser the density, and the lower the altitude the higher the density. Lower density float to the top, and higher density is 'heavy' so it comes down

  • 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.

What is the acceleration of a car that goes from 40km/hr to 80km/hr in 2s?
tresset_1 [31]
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!

A shopping cart is given an initial velocity of 2 m/s and undergoes a constant acceleration of 4 m/s2. What is the magnitude of
Rasek [7]

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.

A 3,162-kg truck moving with a velocity of 12 m/s to the East hits a 510-kg parked car. The impact causes the car to be set in m
Musya8 [376]

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

\begin{gathered} m1v1i+m2v2i=m1v1f+m2v2f \\ v1f\text{ =}\frac{m1v1i-m2v2f+m2v2i}{m1} \\ =\frac{3162\times12-510\times24+510\times0}{3162} \\ =8.129\text{ m/s} \end{gathered}

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