A change that would most improve his results would be; D) Connecting the galvanometer to the coil

Snezhnost [94]3 years ago

Answer: The correct answer is "connecting the galvanometer to the coil".

Explanation:

Electromagnetic induction is the phenomenon of the production of the electromagnetic force across the conductor by changing the magnetic field.

The current can be induced by moving the conductor in the magnetic field. The current can also be induced by changing the magnetic field across the conductor.

The current will be induced into a coil of wire by moving a bar magnet into a coil of wire. It can be observed by connecting the galvanometer to the coil. The galvanometer is an instrument which shows the deflection when the current is flowing in the conductor.

Therefore, the correct option is (D).

binoculars: provide a magnified stereoscopic view of distant objects.

streak plate: is a technique which is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled.

wind vane: is used to determine wind direction.

ruler: is used for measuring a line.

microscope: is used to magnify the objects which are not visible by naked eyes.

magnifying glass: is used to magnifying tiny objects which are difficult to see yet they are visible.

A bullet of mass 0.107 kg traveling horizontally at a speed of 300 m/s embeds itself in a block of mass 3 kg that is sitting at
melisa1 [442]

Answer:

165.77J

Explanation:

M₁ = 0.107kg

u₁ = 300m/s

m₂ = 3kg

u₂ = 0

v =

m₁u₁ + m₂u₂ = (m₁ + m₂)V

(0.107*300) + 0 = (0.107 + 3)V

V = 32.1 / 3.107 = 10.33m/s

kinetic energy of the system after collision =

½m1v² + ½m2v²

K.E = ½(m1 + m2)v²

K.E = ½(0.107+3) * 10.33²

K.E = 165.77J
