Astone is tied to a string (length 1.10 m) and whirled in a circle at the same constant speed in two different ways. first, the circle is horizontal and the string is nearly parallel to the ground. next, the cir- cle is vertical. in the vertical case the maximum tension in the string is 15.0% larger than the tension that exists when the circle is horizontal. determine the speed of the stone.'

v = 1.27 m/s

Explanation:

When stone is moving in horizontal circle with constant speed

then in this case the centripetal force is given as

Now when stone is moving in vertical circle then we will have

now we know that

a sonic boom is a loud boom that breaks the sound barrier

explanation:

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
