3. How can the U.S. economy grow if we import more goods and services?

Naddik [55]

Answer:

A trade deficit therefore occurs when a country spends more on imports than it receives in exports. A budget deficit, in the context of the government, instead occurs when there is more federal spending than revenue taken in from taxes, duties, fines, and other fees.

When a hammer thrower releases her ball, she is aiming to maximize the distance from the starting ring. Assume she releases the

Taya2010 [7]

Answer:

The angular velocity is 15.37 rad/s

Solution:

As per the question:

$\theta = 54.6^{\circ}$

Horizontal distance, x = 30.1 m

Distance of the ball from the rotation axis is its radius, R = 1.15 m

Now,

To calculate the angular velocity:

Linear velocity, v = $\sqrt{\frac{gx}{sin2\theta}}$

v = $\sqrt{\frac{9.8\times 30.1}{sin2\times 54.6}}$

v = $\sqrt{\frac{9.8\times 30.1}{sin2\times 54.6}}$

v = $\sqrt{\frac{294.98}{sin109.2^{\circ}}} = 17.67\ m/s$

Now,

The angular velocity can be calculated as:

$v = \omega R$

Thus

$\omega = \frac{v}{R} = \frac{17.67}{1.15} = 15.37\ rad/s$

La velocidad de la luz en el vacío es c= 3000.000 km\s la luz del sol tarda en llegar a la tierra 8 minutos y 14 segundos

ehidna [41]

La velocidad correcta de la luz en el vacío es 300.000 km/s .

La distancia = (velocidad) x (duración de tiempo)

Duración de tiempo = 494 segundos, porque cada minuto = 60 segundos

La distancia = (300.000 km/s) x (494 s)

<em>La distancia = 148.200.000 km</em>

A ball is dropped from the top of a building that is known to be 400 feet high. The formula for finding the height of the ball a

Ira Lisetskai [31]

Answer:

3 seconds

Explanation:

Height of the building = 400 feet

Height of the ball from the ground is given by

h=400−16t²

This formula has been derived from

$s=ut+\frac{1}{2}at^2$

a = Acceleration due to gravity = 32 ft/s²

u = Initial velocity = 0

t = Time taken

Substituting all the values we get

$s=0t+\frac{1}{2}32t^2\\\Rightarrow s=16t^2$

This is the height of the ball from the top of the building

The height of the ball from the ground will be

h = 400-s

⇒h = 400−16t²

When h = 256 ft

$256=400-16t^2\\\Rightarrow t=\sqrt{\frac{256-400}{-16}}\\\Rightarrow t=3\ s$

Time taken by the ball to reach a height of 256 feet above the ground is 3 seconds
