If $1,800 is invested in a savings account offering interest at a rate of 4.5% per year, compounded continuously, how fast is th

Archy [21]

Answer:

The total amount after 3 years is = $ 2054.10

Explanation:

Given data

Principal Amount (P) = $ 1800

Rate of interest (R) = 4.5 %

Thus the total amount after 3 years compounded annually is given by the formula = P × $[1 +\frac{R}{100} ]^{3}$

⇒ 1800 × $[1 +\frac{4.5}{100} ]^{3}$

⇒ 2054.10

Thus the total amount after 3 years is = $ 2054.10

Compound interest earned in three years = 2054.10 - 1800 = $ 254.10

velikii [3]

Correct answer choice is:

D. A frequency higher than the original frequency.

Explanation:

This is a true case of Doppler's effect. The Doppler effect can be defined as the effect originated by a traveling source of waves in which there is a visible higher variation in pulse for observers towards what the source is progressing and a visible descending shift in rate for observers from what the source is dropping.

After washing lettuce, you can dry the water from it using a salad spinner. You put the lettuce in the bowl, and then crank the

guapka [62]

A. The force that causes the water on the lettuce to come off the lettuce and go to the walls of the bowl is centrifugal force.

<h3>What is centrifugal force?</h3>

Centrifugal force is an inertial force that appears to act on all objects when viewed in a rotating frame of reference.

This force is directed away from the center around which the body is moving.

<h3>What is centripetal force?</h3>

This is force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.

While centripetal force is directed towards to the center, the centrifugal force is directed away.

Thus, the force that causes the water on the lettuce to come off the lettuce and go to the walls of the bowl is centrifugal force.

A volumen constante un gas ejerce una presión de 880 mmHg a 20o Celsius dentro de una olla a presión ¿Qué temperatura habrá si e

jasenka [17]

Answer: Hence, the final temperature is 350 K

Explanation :

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$
