Solution:

The answer is

Resolution:

They knew that once invoked, the executive benefit would shield Bush from investigations. The Bush Administration invoked executive privileges six times. During each time it had done so, it concerned investigations steaming from the war on terror to meeting with government officials as well requiring members of his team to testify.

2. If both the mass and radius of the earth, each decreases by 50%, the acceleration due to gravity would (a) remain same (b) de

Scrat [10]

Answer:

(d) increase by 100%

Explanation:

$m_{i}$ = initial mass of earth = m

$m_{f}$ = final mass of earth = (0.5) m

$R_{i}$ = initial radius of earth = R

$R_{f}$ = final radius of earth = (0.5) R

$g_{i}$ = initial acceleration due to gravity of earth = g

$g_{f}$ = final acceleration due to gravity of earth

initial acceleration due to gravity of earth is given as

$g_{i} = \frac{Gm_{i}}{R_{i}^{2}}$ Eq-1

Final acceleration due to gravity of earth is given as

$g_{f} = \frac{Gm_{f}}{R_{f}^{2}}$ Eq-2

Dividing eq-1 by eq-2

$\frac{g_{i}}{g_{f}} = \frac{m_{i}}{m_{f}}\frac{R_{f}^{2}}{R_{i}^{2}}$

inserting the values

$\frac{g}{g_{f}} = \frac{m_{i}}{(0.5)m_{i}}\frac{(0.5)^{2}R_{i}^{2}}{R_{i}^{2}}$

$g_{f}$ = 2 g

So there is 100% increase

¿Cómo puedes ubicar los puntos cardinales?

tatuchka [14]

Answer:

Ubicar los puntos cardinales es fácil, extendemos los brazos en cruz, señalando con el brazo derecho el lugar por donde aparece el sol en las mañanas , es decir por el Oriente ; el brazo izquierdo indicará el Occidente, osea el lugar por donde vemos escondenderse el sol , la cara señalará el Norte y la espalda el Sur.

Circle the letter of the basic force that drives plate tectonics.

kirill115 [55]

The basic force that drives plate tectonics are the convection currents.

Explanation:

The surface of Earth is cracked and divided into numerous tectonic plates. Some tectonic plates are very large, thus considered as major plates, while some are significantly smaller. There is constant motion of the tectonic plates, and they constantly move in some direction, causing the occurrence of numerous geological activities.

The tectonic plates don't just move on their own, but there is a driving force. That driving force comes from below them, from the mantle layer, in the form of the convection currents. The convection currents basically represent a circular motion (down-up), where the cooler and denser rocks sinks, while the hot and less dense ones go up, making enormous pressure on the surface.

Some of the major tectonic plates are:

Eurasian
North American
African
Pacific etc.

Some of the smaller tectonic plates are:

Arabian
Cocos
Philippine
Juan de Fuca etc.
