1). There will be one great spark across the terminals of the switch as it closes.
2). Current will start to flow through the wire, from the ( + ) of the left-side battery, all the way around the circuit, through the coils wrapped around the nail, to the ( - ) of the right-side battery.
3). The current will be quite large, because the only resistance in the circuit is a bunch of wire, I = V / R, V is around 3 volts, and the resistance of wire is very low.
4). The magnetic field around the wire due to the current flowing through it will cause the nail to become temporarily magnetized.
5). The batteries will peter out after a comparatively short time, the current will die out, and the nail will become non-magnetic, even if the switch stays closed. The batteries may even be warm, but in any case, they will be toast.
Answer:
The distance between interference fringes increases

Answer:
Sooo sorry for the late answer, but I hope it helps
Explanation:
1. Successful variations accumulate over the generations as the organisms are exposed to population pressure. "Natural Selection acts exclusively by the preservation and accumulation of variations which are beneficial under the conditions to which each creature is exposed.
2.The age of fossils are determined by carbon dating and by radioactive calculations. Since all living things are made up of carbon, the relative age of fossils, which were once live animal or plant life, can be calculated by estimating at what time the fossil was alive. When the sun’s rays shine on the animals or plants and when this collides with nitrogen it creates Carbon 14, a radioisotope. Superposition is the action of placing one thing on or above another, especially so that they coincide.
3. The geologic time scale if the record of the major events and changes in earth. Scientists created this in order to keep with the major geographical things happening on earth. Scientists created the geologic time scale using relative dating.
4. Speciation is the method of formation of new species. Speciation is of 3 types. Type 1 Allopatric Speciation Type 2 Sympatric Speciation.
Sympatric speciation happens when members of a population develop genetic differences that prevent them from reproducing with the parent type. Allopatric speciation is the evolution of species in a population that occupy different geographical areas.
5. The discovery of fossil palm tree stumps in Alaska and the unearthing of fossil alligator remains in the Arctic Circle suggested that the high latitudes were a tropical landscape 52 million years ago.

Answer:
F=ma
So we have to find acceleration
V^2-U^2=2as
V=0 ,U=10m/s ,s= 50m
(0)^2-(10)^2=2*50*a
0-100=100*a
-100=100*a
-100/100=a
-1=a
F=ma
F=1000*-1
F= -1000N
Hope this is the right answer
