A baseball pitcher wants to impress his girl-friend with how strong his throwing arm is. On which of the following bodies would the pitcher be MOST likely to be able to throw a baseball (a fast ball) so fast it would actually go into orbit?
A) Earth
B) Mars
C) Ganymede
D) Titan
E) asteroid Ida

Answers

The correct and only reasonable answer is A

The body which the pitcher would be MOST likely to be able to throw a baseball (a fast ball) so fast it would actually go into orbit is:

E. Asteroid Ida

Asteroid Ida is a small planet which was discovered in 1884 and was given its name from a Greek historical figure.

As a result of this, we can see that if the baseball pitcher wants to throw a baseball so fast that it would go into orbit, then he would most likely throw it towards Asteroid Ida.

This is because, Asteroid Ida has a small diameter of 31.4km and it moves around Mars and Jupiter which makes it easier to reach. Its rotation period is about 4 and a half hours.

Therefore, the correct answer is option E

Though Nepal is rich in natural resorces, it could not achieve level of development performance , justify the statement .​

Answers

Both the economy and government of Nepal have been extremely volatile. There has been substantial influence thwarted by larger, more developed nations that continue to show drastic fluctuations in economic stability, self-sufficiency, and sovereignty.

Additionally, the current primary industries do not seem to be encouraging the expansion into technology like so many of the more developed nations. Globalization has been relatively nonexistent and there remains little incentive to expand and promote international trade/commerce.

Without ample infrastructural change and major technological and or industrial revolutions, the nation will likely not see the great economic growth displayed by both Saudi Arabia and the United Arab Emirates, both notably rich and heavily dependent on natural resources

recommend how the local government can regulate and control laws in a community

Answers

Explanation:

Communities operate in the context of federal and state policies that can affect local government decisions relevant to health through laws and regulations, through the allocation of resources, and by shaping political will on issues and approaches. Among the more widely recognized policies are those that fund or regulate health care delivery services. But policies in a variety of areas, ranging from education to land use and housing, the environment, and criminal justice, can be relevant to health disparities. Policies can vary significantly across geographic areas and over time in establishing priorities, providing funding, or encouraging collaboration. They can provide important opportunities or constitute barriers to promoting health equity. The policy context shapes the levers that are available to communities to address change.

It seems reasonable to assume that the better informed communities are about the implications of federal and state policy and policy changes, the greater their ability will be to respond effectively to address health disparities and help achieve change in the determinants of health. And, conversely, the more the needs of communities are considered in decision making at the federal and state levels, the more effective those policies will be. In other words, policy makers have the opportunity to lay the groundwork for community success.
