Answer:

8.5

Explanation:

To the nearest tenth of a year, it would take around 9.1 years when calculate compoundly for the account's worth to reach $20,600.

A loan or investment's initial principal as well as any accrued interest from earlier periods are both taken into account when calculating compound interest.

To resolve this issue, we can apply the compound interest formula:

A = P(1 + r/n)nt

where:

When A = $20,600, we need to determine t. Since we are aware that the initial investment would double after seven years, we can use the following formula to determine the yearly interest rate:

2 = (1 + r/n)^(nt)

If n is 1/7 (since the investment twice once every 7 years), 2 is the factor by which the investment doubles, and t is an unknown.

When we simplify this equation, we obtain:

t log(1 + r/7) = log(2)

When we solve for r, we get:

r = 7[(2^(1/t))-1]

Now that we have P, r, n, and A, we can enter them into the compound interest formula to find t:

$20,600 = $8,900(1 + r/1)^(1t)

2.318 = (1 + r)^t = log (2.318) / log (one plus r)

t is equal to log(2.318)/log(1 + 7[(2(1/t))-1]).

We can iteratively solve for t using a calculator, beginning with a first guess of 7 years (because the investment doubles every 7 years):

r = 0.0998 and A = $17,800 for t = 7 years

r = 0.0909 and A = $19,397 for t = 8 years.

r = 0.0833 and A = $20,416 for t = 9 years.

r = 0.0823 and A = $20,601 (closest to $20,600) for t = 9.1 years

As a result, it would take the account's value to reach $20,600 in around 9.1 years (to the nearest tenth of a year).

Therefore, when calculated compoundly, it would take approximately 9.1 years for the account's value to reach $20,600, to the nearest tenth of a year.

Answer: Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. Therefore when mass is decreased, an increase in kinetic energy is possible if velocity increases.

Answer:: Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two.

Answer:

300 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

s = 40 × 15 / 2

s = 600 / 2

s = 300 m

Thus, the distance travelled by the motorbike is 300 m.

Answer:

A. The path of least resistance.

Explanation:

ur welcome again ;)

An electric current will always follow the path of least resistance. So, the right option is a.

In inverse relation to the resistance of the pathways, electric current follows every available paths.

The voltage and resistance of the path in the electric circuit affect the amount of electric current that flows through the circuit.

The quantity of electric current flowing through the circuit is inversely proportional to the resistance in the circuit.

Assuming a fixed voltage, the current increases with decreasing resistance. The current decreases in accordance to the level of increasing resistance.

Explanation:

The frequency of earthquake = 2.0 Hz

The wavelength = 35 m

How fastbthw earthquake is t traveling is given bythw velocity of the wave, velocity of wave is related to frequency and wavelength using the formula :

V = frequency * wavelength

V = 2 * 35

V = 70 m/s

Answer:

The answer is "The frequency of the sound waves increases".

Explanation:

Its most oscillating their frequency waves, therefore higher the vibration we hear. However you see, sound frequency is determined through the oscillation of electrical signals while moving to our ears, which implies that perhaps the audio medium, which usually is air, makes a distinction between compression to spreading. It's the end of the communication as the frequency rises.

Answer:

La velocidad del sistema bala-bloque es 5 metros por segundo.

Explanation:

El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:

Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:

[tex]m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v[/tex] (1)

Donde:

[tex]m_{b}[/tex] - Masa de la bala, en kilogramos.

[tex]v_{b,o}[/tex] - Velocidad inicial de la bala, en metros por segundo.

[tex]m_{B}[/tex] - Masa del bloque, en kilogramos.

[tex]v[/tex] - Velocidad del sistema bala-bloque, en metros por segundo.

Si sabemos que [tex]v_{b,o} = 30\,\frac{m}{s}[/tex], [tex]m_{b} = 0.8\,kg[/tex] y [tex]m_{B} = 4\,kg[/tex], entonces la velocidad del sistema masa-bloque es:

[tex]v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}[/tex]

[tex]v = 5\,\frac{m}{s}[/tex]

La velocidad del sistema bala-bloque es 5 metros por segundo.

Answer:

Speed = 3 m/s

Explanation:

Given the following data;

Distance = 2700m

Time = 900 s

To find the speed;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting into the equation, we have;

[tex]Speed = \frac{2700}{900}[/tex]

Speed = 3 m/s

Answer:

Time = 43.88 seconds

Explanation:

Given the following data;

Speed = 2.5 m/s

Distance = 109.7 m

To find the time it would take to run the length of a standard football field, we would use the following formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making time the subject of formula, we have;

[tex]Time = \frac{distance}{speed}[/tex]

Substituting into the formula, we have;

[tex]Time = \frac{109.7}{2.5}[/tex]

Time = 43.88 seconds

Therefore, it would take a tiger beetle 43.88 seconds to run the length of a standard football.

Answer:

1. 5 V

2. A₂ = 1.2 A

Explanation:

1. Determination of the voltage measured at R₃.

Voltage at R₁ (V₁) = 1 V

Voltage at R₂ (V₂) = 6 V

Total voltage (Vₜ) = 12 V

Voltage at R₃ (V₃) =.?

Vₜ = V₁ + V₂ + V₃

12 = 1 + 6 + V₃

12 = 7 + V₃

Collect like terms

12 – 7 = V₃

V₃ = 5 V

Thus, the voltage measured at R₃ is 5 V

2. Determination of A₂.

From the circuit diagram, we can see that the resistors are in series arrangement. This means that the same current will pass through each resistor.

Thus,

A₂ = A₁ = 1.2 A

The smaller the mass of an object, the smaller its inertia, because the inertia of any object is directly proportional to the mass of the object

The ability of an object to resist changes in motion is known as inertia. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.

A straightforward illustration: While it is relatively simple to stop a tennis ball that has been thrown in our direction, we are aware that it is more difficult to stop a large truck that is moving in the same direction at the same speed. This is because the truck has a much higher mass than the tennis ball and a higher moment of inertia. As a result, inertia rises as mass does.

Since the inertia of any object is directly proportional to its mass, the smaller its mass, the less inertia it will have.

Answer:

the angular speed of the stone at the moment of release is 15.05 rad/s

Explanation:

Given the data in the question;

The point of release ( height ) h = 25.6 m

the time of the fall of the stone will be;

⇒√( 2h/g )

we know that g = 9.81 m/s

so we substitute

t = √( (2 × 25.6 m) / 9.81 m/s )

t = √( 51.2 / 9.81 m/s )

t = √( 5.219164 s )

t = 2.285 s

Now, let v represent velocity at the time of release

them v × t ~ v × 2.285 s is the horizontal distance traveled.

Given that; The horizontal distance of point X from the base of the cliff (directly beneath the point of release) is 34.4 times the radius of the circle.

so

v × 2.285 = 34.4 × radius

Now, if the angular speed is ω then velocity at the time of release will be;

v = radius × ω

hence;

(radius × ω)  × 2.285 = 34.4 × radius

radius cancels each other out and we have;

ω  × 2.285 = 34.4

ω = 34.4 / 2.285

ω = 15.05 rad/s

Therefore, the angular speed of the stone at the moment of release is 15.05 rad/s
