Answer:
7066kg/m³
Explanation:
The forces in these cases (air and water) are: Fa =mg =ρbVg Fw =(ρb −ρw)Vg where ρw = 1000 kg/m3 is density of water and ρb is density of the block and V is its density. We can find it from this two equations:
Fa /Fw = ρb / (ρb −ρw) ρb = ρw (Fa /Fa −Fw) =1000·(1* 21.2 /21.2 − 18.2)
= 7066kg/m³
Explanation:
A magnet sitting next to a wire does not induce a current in the wire because <span> the magnet is very small and short compared to the coil radius. If you pretend it's two individual monopoles, they're only a few mm apart, so at several cm there's almost perfect cancellation of the fields.</span>
Answer:
D. When the temperature of the gas is the same throughout
Explanation:
Answer:
Vertically
Explanation:
Pressure changes faster as we move vertically because as we go to the height from the surface of the earth. The density of air becomes lesser in comparison with the surface of the earth. So, as we move vertically pressure moves faster than in comparison with the vertical movement.
The best example that describes the above statement is the hill station.
Answer:
Upward.
Explanation:
A large reduction in the current account deficit will place Upward pressure on the home currency value, other things being equal.
When their currency's value decreases, this means the valuation of foreign assets are rising. This further decreases the deficit in the current account. Additionally, a reduced currency value tends to increase export markets when prices become more cutthroat. Export demand falls as prices rise with inflation setting in.
