Answer:

1788 grams

Step-by-step explanation:

If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes

We are to find Nt

The formula is given as:

Nt = No(1/2)^t/t½

Where

No = Initial amount = 7,152 grams

t = time elapsed = 186 minutes

t½ = Half life = 93 minutes

Nt = Amount of substance left

Nt = 7152(1/2)^186/93

= 1788 grams

Answer:

1) La velocidad de la bala después de atravesar el muro es de aproximadamente 435,890 metros por segundo.

2) La potencia del automóvil es 96438,272 watts o 131,208 caballos de vapor.

3) La velocidad del objeto al llegar al suelo es aproximadamente 14,005 metros por segundo.

Step-by-step explanation:

1) La velocidad final de la bala puede determinarse mediante el Teorema del Trabajo y la Energía, a partir del cual se tiene la siguiente fórmula:

[tex]\frac{1}{2}\cdot m\cdot v_{o}^{2} -F\cdot \Delta s = \frac{1}{2}\cdot m \cdot v_{f}^{2}[/tex] (1)

Where:

[tex]m[/tex] - Masa de la bala, en kilogramos.

[tex]v_{o}, v_{f}[/tex] - Velocidades inicial y final de la bala, en metros por segundo.

[tex]F[/tex] - Resistencia del muro al avance de la bala, en newtons.

[tex]\Delta s[/tex] - Espesor del muro, en metros.

Si sabemos que [tex]m = 0,01\,kg[/tex], [tex]v_{o} = 500\,\frac{m}{s}[/tex], [tex]F = 3000\,N[/tex] and [tex]\Delta s = 0,1\,m[/tex], entonces la velocidad final de la bala es:

[tex]v_{f}^{2}=v_{o}^{2} -\frac{2\cdot F\cdot \Delta s}{m}[/tex]

[tex]v_{f} = \sqrt{v_{o}^{2}-\frac{2\cdot F\cdot \Delta s}{m} }[/tex]

[tex]v_{f} \approx 435,890\,\frac{m}{s}[/tex]

La velocidad de la bala después de atravesar el muro es de aproximadamente 435,890 metros por segundo.

2) Asumamos que el automóvil acelera a tasa constante, significando que la fuerza neta será constante. Para un sistema cuya fuerza neta sea constante, la potencia experimentada queda descrita por la siguiente ecuación:

[tex]P = m\cdot a(t)\cdot v(t)[/tex] (2)

[tex]a(t) = a[/tex] (3)

[tex]v(t) = v_{o} + a\cdot t[/tex] (4)

Donde:

[tex]P[/tex] - Potencia, en watts.

[tex]m[/tex] - Masa del automóvil, en kilogramos.

[tex]a(t)[/tex] - Aceleración, en metros por segundo al cuadrado.

[tex]v(t)[/tex] - Velocidad, en metros por segundo.

[tex]v_{o}[/tex] - Velocidad inicial del automóvil, en metros por segundo.

Si sabemos que [tex]m = 1000\,kg[/tex], [tex]a = 3,472\,\frac{m}{s}[/tex], [tex]v_{o} = 0\,\frac{m}{s}[/tex] y [tex]t = 8\,s[/tex] entonces la potencia experimentada por el automóvil es:

[tex]P = 96438,272\,W[/tex] ([tex]131,208\,C.V.[/tex])

La potencia del automóvil es 96438,272 watts o 131,208 caballos de vapor.

3) El cuerpo experimenta un Movimiento de Caída Libre, el cual es un Movimiento Uniformemente Acelerado debido a la gravedad terrestre. La velocidad del cuerpo al llegar al suelo se determina mediante la siguiente fórmula cinemática:

[tex]v_{f} = \sqrt{v_{o}^{2}+2\cdot g\cdot h}[/tex] (5)

Donde:

[tex]v_{o}[/tex] - Velocidad inicial del cuerpo, en metros por segundo.

[tex]v_{f}[/tex] - Velocidad final del cuerpo, en metros por segundo.

[tex]g[/tex] - Aceleración gravitacional, en metros por segundo al cuadrado.

[tex]h[/tex] - Altura recorrida por el cuerpo, en metros.

Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]g = 9,807\,\frac{m}{s^{2}}[/tex] y [tex]h = 10\,m[/tex], entonces la velocidad al llegar al suelo es:

[tex]v_{f} \approx 14,005\,\frac{m}{s}[/tex]

La velocidad del objeto al llegar al suelo es aproximadamente 14,005 metros por segundo.

Answer:

[tex]Longer\ leg = 8[/tex]

Step-by-step explanation:

Given

30-60-90 triangle

[tex]Shorter = \frac{8}{\sqrt 3}[/tex]

Required

The longer leg

The following relationship exists in a 30-60-90 triangle.

[tex]Longer\ leg = \sqrt 3 * Shorter\ Leg[/tex]

This gives:

[tex]Longer\ leg = \sqrt 3 * \frac{8}{\sqrt 3}[/tex]

[tex]Longer\ leg = 1* \frac{8}{1}[/tex]

[tex]Longer\ leg = 1* 8[/tex]

[tex]Longer\ leg = 8[/tex]

Answer:

Each orange would cost $0.64.

Step-by-step explanation:

If you do 3.84 and divide that by 6, you would get the answer of $0.64 for each orange.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The cost of one orange is $0.64

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

6 oranges = $3.84

Divide both sides by 6.

1 orange = $3.84/6

1 orange = $0.64

Thus,

The cost of one orange is $0.64.

Answer:

Range

Step-by-step explanation:

To obtain the difference between two extreme values (peak or highest and the bottom or lowest) value of a distribution, the statistical measure which best captures this differ ce is the RANGE. As the range is specifically used for determining the variation between the highest and lowest value of dataset.

The range is defined Mathematically as ;

Range = Maximum value - Minimum value

Hence. To obtain the difference between the maximum and least number of votes, the range is the best measure to use.

Answer:

  y = x + 4

Step-by-step explanation:

Since x > 5, x-3 > 0, x + 2 > 0 and x - 5 > 0

So Ix - 3I = x - 3,   Ix + 2I = x + 2   and x - 5 = x - 5

Therefore, y = x - 3 + x + 2 - x + 5

                  y = x + 4

Answer:

Step-by-step explanation:

It might interest you to know what this question means without the restriction. See graph 36b. This shows exactly what happens to the absolute value. There are all sorts of turns and twists in it. Notice all the changes in direction and the minimum at -2,-2. The y intercept is at 0,0.

0,0 is also one of the x intercepts as well. The other is -4,0. The whole point of showing you this is to make you aware of what the restriction does.

The graph is reduced to a line starting at (5,9)

Step-by-step explanation:

you need either:

the diameter- the distance from one side to the other, or

the Radius- the distance from the center to the edge

the diameter is always double the radius, and accordingly the radius is always half the diameter.

so, the circumference ca be figured out by multiplying the diameter times pi- which, for most calculations is 3.14

if you only have the radius, multiply that by 2 to get the diameter, then by 3.14.

hope that helps!

Answer:

you have to do 9/2 and then times that by twenty four. that will give you 108

Answer:

60 compounding periods

Step-by-step explanation:

The proper formula for compound interest is A = P(1 + r/n)^(nt), where r is the interest rate as a decimal fraction, n is the number of times that interest is compounded in 1 year, and t is the number of years.

In this problem, we don't need to calculate the Amount, but only the number of compounding periods.  That is nt, which here is 12*5, or 60.

Answer:

1st year is $75,000 * 0.04 = $3,000 $75,000+$3,000=$78,000
