What asteroid is the most speed and powerful impact in the world​

asteroid 2001 FO32

Explanation:

The asteroid 2001 FO32 is hurtling through space at an unusually fast speed for a space rock, about 77,000 mph (124,0000 kph), and will pass by Earth at a safe range of 1.25 million miles (2 million kilometers), according to NASA. It won't come this close to Earth again until 2052.

no

Explanation:

No. An impact powerful enough to alter Earth's rotation speed would have to be at least about half the diameter of the moon. And the impact would have to occur near along the Earth's equator. Or else the impact would only knock the Earth on its axis, causing the Earth to tilt at an angle of less than or greater than 23 degrees - the current angle of its axis. And even so, the force of such an impact at would only slightly, alter the rate of the Earth's rotation. But due to the g-force of the Earth's rotating axis, and since the Earth rotates west to east, such an impact at an eastern direction would have a greater affect than an impact at a western angle would have on the Earth's rotation speed.

the reform movements that arose during the antebellum period in america focused on specific issues: temperance, abolishing imprisonment for debt, pacifism, antislavery, abolishing capital punishment, amelioration of prison conditions (with prison's purpose reconceived as rehabilitation rather than punishment), the humane treatment of animals, the humane and just treatment of native americans, the establishment of public institutions for the care of the destitute, orphans, blind, and mentally ill, the establishment of public schools, the abolition of tobacco use, vegetarianism, health reform, homeopathic medicine, woman's rights (including, at first, especially the establishment of a woman's right to own property apart from her husband and her right to sue for divorce), and the amelioration of labor conditions (including higher pay, the right to form unions, the right to strike, and the demand for limits on the number of work hours, and safe working conditions).
