A Buck-Boostconverter with an input voltage of 100 V is used to regulate the load voltage. The on-time of the switch is alwaysfixed at 0.1 ms and the switching frequency is adjustedto regulate the load voltage. Find the switching frequencies to achieve an output voltage of40 V and 120 V, respectively.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
