Describe the directive property of a magnet |
|
Answer» ong>Answer: The directive property of a magnet explains its tendency to align itself along an external magnetic field. When a magnet is suspended freely in AIR with the help of a THREAD then it tends to align itself in the geographic north-south DIRECTION. This property of magnet is known as directive property of target. hope it helps you! mark me as BRAINLIST and follow!! |

State basic laws of magnetisation |
|
Answer» When the north pole of a magnet is BROUGHT closer to the south pole of ANOTHER magnet, there is an attractive force that brings the MAGNETS together. If the magnet is turned so that two north poles or two poles are brought closer, they will repel each other. This ACTUALLY demonstrates the two basic laws of magnets. The two basic laws can be stated as: ●Like poles (North-North, South-South) will repel each other• ●Unlike poles (North-South) will ATTRACT each other• |

When 80g of water of 40° C is mixed with 40g ice of 0°C, the common temperature is .. |
|
Answer» ong>Answer: I got about 31.4 ∘ C . This is asking you to look at the HEAT transfer between a hotter substance and a colder substance, and the hotter transfers to the colder. I would EXPECT the result to be closer to 25 ∘ C than to 40 ∘ C because there is more colder water than hotter water. So, you will have to use the heat FLOW equation: q = ± m c Δ T = ± m c | T f − T i |
Keep in mind that q > 0 if heat is absorbed and q < 0 if heat is released. So q < 0 for the hotter water and q > 0 for the colder water. That is so that: q hotter + q colder = 0 , i.e. we have conservation of energy for ideal closed systems. |
