The correct option is D.
Micheal Friday devised a wire which hanged down into a glass vessel that has a bar magnet secured at the bottom. He then filled the glass vessel with Mercury and connected the apparatus to a battery. This sent electricity through the wire, thus creating a magnetic field around it. This field interacted with the field around the magnet and cause the wire to rotate clock wisely.
Answer:
If we have large numbers (b is positive) or small numbers (b is negative), then this way ... 1, and V2i = 100 L, n2i = 5 + 2 + 1 = 8 in vessel 2. ... a good working substance in the barometer.
Answer:
b. Icy objects that form a tail as they come close to the Sun
Explanation:
Acording to NASA comets are cosmic snowballs made out of frozen gases, rock and dust, they usually are the size of a small town and contain water and organic compounds due to the collisions with Earth and other planets. When its orbit brings it close to the sun, it heats up, spewding dust and gases forming a tail that streches away from the sun, they also have a glowing head that is larger than most planets.
<em>Considering this information we can conclude that the correct answer is b. Icy objects that form a tail as they come close to the Sun.</em>
I hope you find this information useful and interesting! Good luck!

Answer:
Explanation:
Given
Speed v =27m/s
Distance covered after skidding = 41.5m
Acceleration a = ?
Using the equation of motion
v² =u²+2aS
27² = 0²+2a(41.5)
729 = 0+83a
a = 729/83
a = 8.78m/s²
Hence it's acceleration is 8.78m/s²
