<span>You have just demonstrated an insight learning. Internal insight occurs if one learned a new way without the help of environmental factors. In here, what the person initially learned that if one saw a broken light bulb from a lamp, he can be cut through the jagged glass if one does not wear a pair of gloves. And maybe because at the moment, the person could not find one, he felt using a cut potato to pick up the pieces of the broken lamp. This is a demonstration of insight learning. The person found a way to pick up the pieces of the broken lamp by using his instinct at the moment. The person is not influenced by an outside source to tell him to use a potato. </span>
Universe contains billions and billions of stars, galaxies, planets, asteroids, comets and many more different type of bodies. These objects emit radiations of varied frequency. In order to study these different kind of objects, different kind of technology is required. There are different type of missions: some contain probes which land on the surface, some orbit the bodies etc. These are for solar system. Yet some are space observatories having detectors to study light from distant objects. Further, there are different detectors for different wavelengths of electromagnetic spectrum.
Answer:
Explanation:
The emf induced in a straight conductor of length l moving with velocity v perpendicular to a magnetic field B is
E = Blv
where B, l and v are perpendicular. The emf, E is in volts
Magnetic field, B is in webers/m2
= 1.2 T
length is in meters
= 0.15 m
velocity, v is in m/sec
= 8 m/s
E = 1.2 × 0.15 × 8
= 1.44 V
B.
Using ohm's law,
V = I × R
I = 1.44/200
= 0.0072 A
C.
F = B × I × L
= 1.2 × 0.0072 × 0.15
= 0.001296 N
ok i can help you what are your questions
