| a. | | Remain equal to T |
| b. | | Become 6T |
| c. | | Become 2.44T |
| d. | | Become T/2.44
|
|
|
|
|
|
|
| 9. | The atmospheric pressure on earth is due to |
| a. | | The gravitational exerted on earth by the moon |
| b. | | The gravitational force exerted on earth by the sun |
| c. | | The weight of all the air in the earth's atmosphere |
| d. | | The weight of the ionized gases in the ionosphere
