15 number of division on Vernier scale and 12 cm on the main scale means 13.2 cm of the object thickness.

<h3>What is value of 15 division of Vernier scale generally?</h3>

A Vernier scale has 10 divisions and the total length of these 10 divisions is equal to the length of 9 divisions of the main scale that equals to 9 mm so in this way 15 number of division on Vernier scale means 14 divisions on the main scale which is equals to 14 mm and we know that there is 12 cm on the main scale so by adding 12 cm and 14 mm we get the 13.2 cm reading of the object thickness. Vernier caliper is a measuring device that comprise of a main scale and a sliding jaw with an attached Vernier.

So we can conclude that 15 number of division on Vernier scale and 12 cm on the main scale means 13.2 cm of the object thickness.

A 22.0 kg bucket of concrete is connected over a very light frictionless pulley to a 375 N box on the roof of a building as show

Veronika [31]

Answer:

vf = 3.27[m/s]

Explanation:

In order to solve this problem we must analyze each body individually and find the respective equations. The free body diagram of each body (box and bucket) should be made, in the attached image we can see the free body diagrams and the respective equations.

With the first free body diagram, we determine that the tension T should be equal to the product of the mass of the box by the acceleration of this.

With the second free body diagram we determine another equation that relates the tension to the acceleration of the bucket and the mass of the bucket.

Then we equalize the two stress equations and we can clear the acceleration.

a = 3.58 [m/s^2]

As we know that the bucket descends 1.5 [m], this same distance is traveled by the box, as they are connected by the same rope.

$x = \frac{1}{2} *a*t^{2}\\1.5 = \frac{1}{2}*(3.58) *t^{2} \\t = 0.91 [s]$

And the speed can be calculated as follows:

$v_{f}=v_{o}+a*t\\v_{f}=0+(3.58*0.915)\\v_{f}= 3.27[m/s]$

A lone neutron spontaneously decays into a proton plus an _______

frosja888 [35]

Answer:

A lone neutron spontaneously decays into a proton plus an electron.

Explanation:

In an atom, nuclei contain protons and neutrons, which are the fundamental particles of an atom. Neutrons are stable and uncharged particles inside a nucleus.

For 15 times during its lifetime, a free neutron decays and breaks down into more smaller particles.This breakdown causes problems in nuclear reactors, as they start decaying and emit radiations of different wavelengths.

A neutron undergoes the decaying process to produce an electron, a proton, and energy.

The reaction of neutron decay:

n0 → p+ + e− + νe
