First of all, an alpha particle consists of two protons and two neutrons (similar to a Helium atom). When an atom emits an alpha particle, its nucleus loses two protons and two neutrons. And its total mass decreases by 4 atomic mass units.(As mass of a proton or a neutron is 1 amu)
There are two kinds of beta emissions (or particles) positron or electron.
When an atom emits a
(positron) particle, actually one if its protons releases the particle. Since a positron's charge is positive, when the atom releases a positron it loses its positive charge and turns into a neutron.
When an atom emits a
(electron) particle, one of its neutrons releases a
(electron). And since an electron's charge is negative (-) the neutron loses its negative charge (since neutron's electrical charge is neutral) and turns into a proton.
This is simply explained ^
There are some other details but this should be enough :)
The net force is the centripetal force is 3.56 N.
F1= 3N
F2 = m v²/r
F 2= 0.150 kg*(2.8 m/s)^2/0.75 m
F2= 0.56N
Net force = F1+F2=3N+0.56N= 3.56 N.
As an object moves, the centripetal force pulls or pushes it towards the center of a circle, generating angular or circular motion. The force of tension on the rope pushes the object towards the center while spinning a ball on a string or twirling a lasso.
Centripetal force is described as the force acting on a body traveling in a circular route that is directed toward the body's center. The name is derived from the Latin words centrum, which means "center," and petere, which means "to seek." The centripetal force is the center-seeking force.

Answer:
Explanation:
First off, this lens is concave. Second, the image is obviously smaller, and third, the only thing that is NOT obvious, is the fact that real images are always upside down and virtual images are always right-side-up. So the choice you're looking for is D.
Answer:
moving slowly is the answer
