Answer:

Energy and another nucleus of the new element/particle.

Explanation:

A nuclear decay is an radioactive decay where the nucleus of an atom becomes unstable and loses energy through emitting radiations.For example, there is an alpha decay that release an alpha particle called helium-4, a beta decay that involve releasing a beta particle which normally occurs in a nucleus that has more neutrons than protons.Other decays are the gamma decay,electron capture and the spontaneous fission.Nuclear decay produces a lot of energy and radiations that could harm human cells if exposed.

How would i solve these problems, nobody in my class understands and there is a substitute

DiKsa [7]

1) X-component: 568.5 N, Y-component: 511.9 N

2) The horizontal force is 86.6 N and the resulting acceleration is $0.87 m/s^2$

Explanation:

In this first part of the problem, we have to resolve the force into its two components, along the x and the y direction.

The two components are given by:

$F_x = F cos \theta\\F_y = F sin \theta$

where

F = 765 N is the magnitude of the force

$\theta=42.0^{\circ}$ is the angle of the force with the horizontal

Substituting, we find:

Horizontal component: $F_x = (765)(cos 42.0^{\circ})=568.5 N$
Vertical component: $F_y = (765)(sin 42.0^{\circ})=511.9 N$

First of all, we have to find the horizontal component of the pulling force, which is given by

$F_x = F cos \theta$

where

F = 100 N is the magnitude of the pulling force

$\theta=30.0^{\circ}$ is the direction of the force with the horizontal

Substituting,

$F_x = (100)(cos 30^{\circ})=86.6 N$

Now we can find the acceleration of the wagon by using Newton's second law:

$F_x = ma_x$

where

$F_x = 86.6 N$ is the net force in the horizontal direction

m = 100 kg is the mass of the wagon

$a_x$ is the acceleration in the horizontal direction

Solving for $a_x$ , we find

$a_x = \frac{F_x}{m}=\frac{86.6}{100}=0.87 m/s^2$

How many neutrons is there in that element that has 36 protons and 36 electrons

bagirrra123 [75]

You need to know the mass number to work it out. I can see you have it but it's not visible on your photo.

Every proton weighs 1 and every neutron weighs 1 so if you know the total mass of the nucleus and the number of protons, then you can do:
Mass Number - Proton Number = Neutron Number
because the rest of the mass (that isn't from the protons) must come from the neutrons. Make sense?
