Ebony's bank balance 1st reached $400 on Day 4. The last day her balance was $400 was Day 8.

Tanya [424]

Ebony’s bank balance is $400 was Day 8 and this can be explained below.

<h3>How to explain the information?</h3>

Jade cannot be true because for every transaction made during withdraws, a little amount of money is collected and as such the amount will never remain $400.

Note that the scenario for the above to occur is:

On day 4, her balance = $400

On day 5, her balance = $40

On day 6, her balance = $400

On day 7, her balance = $400

On day 8, her balance = $400

Another fact is that since she deposited 400 at first, on day 8, there will be a 0 increase so the amount will still be 400.

Therefore, if the above is the case, one can deduce the fact that her balance will still be $400.

Desde la parte más alta de un edificio a 25 m una persona lanza hacia la base un objeto de 150 g con una velocidad de 0.8 m por

ANTONII [103]

Answer:

$E_{T} = 36.84 J$

Step-by-step explanation:

La energía mecánica total está dada por:

$E_{T} = E_{c} + E_{p}$

$E_{T} = \frac{1}{2}mv^{2} + mgh$

En donde:

m: es la masa = 150 g

v: es la velocidad = 0.8 m/s

h: es la altura = 25 m

g: es la gravedad = 9.81 m/s²

$E_{T} = \frac{1}{2}mv^{2} + mgh = \frac{1}{2}0.15 kg*(0.8 m/s)^{2} + 0.15 kg*9.81 m/s^{2}*25 m = 36.84 J$

Por lo tanto, la energía mecánica total es 36.84 J.
