Answer:

13 m/s

Explanation:

The computation of the final velocity is shown below;

We know that

v^2 = u^2 + 2as

Here v represent the final velocity

u denotes the initial velocity

a denotes the acceleration

And, s denotes the displacement

So, the final velocity is  

v^2 = (5)^2 + 2(8)(9)

= sqrt(25 + 144)

= sqrt(169)

= 13 m/s

Calculate the power provided by a 12 volt car battery with a rating of 350 amperes.
mamaluj [8]

Answer:

Option D

4200 W

Explanation:

Power, P is also given as the product of voltage and current, expressed as P=VI

Here, P is power, V is voltage in the xircuit and I is current theough voltage.

Taking 12 V for voltage across and 350A for current across circuit then power will be

P=350*12=4200 W

Therefore, option D is correct.

Bromium has two naturally occurring isotopes: 79br, with an atomic weight of 78.918 amu, and 81br, with an atomic weight of 80.9
saul85 [17]

The two different isotopes have weights :

w1 = 78.918 amu

w2 = 80.916 amu

average weight w3 = 79.903 amu

The mixing of two components can be modeled as

let the fraction of w1 be 'x'

hence w1. x + w2.(1-x)  = w3

now this is a linear equation in 'x'. Substituting the values we get

x = 0.507

hence the percentage of Br79 = 50.7% and the percentage of BR81 = 49.3%
