The solstices and equinoxes are all phenomenon that occur during certain seasons. There is a summer solstice and a winter solstice. The winter solstice is the shortest day of the year, as the summer solstice is the longest day of the year. During the solstice the sun is either at the highest point or the lowest point at noon. The Equinox is when the sun crosses the celestial equator, making day and night equal length. Equinox happens twice a year, during fall and spring.

A TMS (transcranial magnetic stimulation) device creates very rapidly changing magnetic fields. The field near a typical pulsed-

GrogVix [38]

Explanation:

It is given that, the field near a typical pulsed-field machine rises from 0 T to 2.5 T in 200 μs

Change in magnetic field, $dB=2.5\ T$

Change in time, $dt=200\ \mu s=200\times 10^{-6}\ s=2\times 10^{-4}\ s$

Diameter, d = 2.3 cm

Radius, r = 0.0115 m

Emf is induced in the ring as the field changes. It is given by :

$E=\dfrac{d\phi}{dt}$

$E=\dfrac{d(B.A\ cos(0))}{dt}$

$E=A\dfrac{d(B)}{dt}$

$E=\pi (0.0115)^2\dfrac{2.5}{2\times 10^{-4}}$

E = 5.19 volts

So, the emf induced in the ring is 5.19 volts. Hence, this is the required solution.

You are riding a skateboard and hit a hole in the street, causing you to fly off the board and crash. Which law represents this

ZanzabumX [31]

Answer:

Newton's first law of motion states that an object at rest will remain at rest and an object in motion will remain in motion unless it is acted on by an unbalanced force. Using unbalanced forces to control the motion of a skateboard demonstrates Newton's first law of motion.

Hope it helps

What energy transformation occurs when a skydiver first jumps from a plane

d1i1m1o1n [39]

The skydiver jumping from a plane high up in the sky would most likely experience various energy transformation. For starters, it would undergo a very large gravitational potential energy because of its much higher elevation. After jumping, this energy would eventually transform to kinetic energy due to the force exerted by the gravity.
