Answer:
1. 3) only a constant gravitation force that acts downward
2. b) Equal to the accleration at the surface of the asteroidc)
Explanation:
1.
- In absence of atmosphere, the force that will act on the steroid is the force of gravity due to asteroid.
- Gravitational force is a long range force acting always attractive in nature.
- It is a contact-less field force which does not requires a medium.
Mathematically given as:
where:
G = gravitational constant
are the mass of the two objects
radial distance between the two objects.
2.
The acceleration of the ball at the top height of the path is still under the influence of the gravity of the two masses so it will be equal to the acceleration due to gravity at the surface of the asteroid. Acceleration always remains constant.
The electron is a type of low-mass, very negatively charged with a particle. As such, it can easily be deflected by passing close to other electrons or the positive nucleus of an atom. m = mass of an electron in kg = 9.10938356 × 10-31 kilograms. e = magnitude of the charge of an electron in coulombs = 1.602 x 10-19 coulombs. Hope this helps!
The radius of curvature of the proton's path while in the field is

.
b) Let R = radius curvature of protons path. Then,
relation b/w B, R, and v is: -
×
Hence, the radius of curvature of the proton's path while in the field is × .

What do you mean by Magnetic field?</h3>
The magnetic influence on moving electric charges, electric currents and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field. The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. A magnetic field that varies with location will also exert a force on a variety of non-magnetic materials by changing the velocity of those particles' outer electrons. Electric currents, like those utilized in electromagnets, and electric fields that change in time produce magnetic fields that surround magnetized things.

The statement that accurately describes a proper use of eyeglasses is statement A. Using converging lenses to help a nearsighted person by moving the image from in front of the retina to the retina.
Answer:
Explanation:
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.
