Which description matches up correctly with each type of particle? Alpha - no mass and no charge; beta - mass of 4 and charge of
Veseljchak [2.6K]
The closest answer is
Alpha - mass of 4 and charge of +2; beta - no mass and charge of -1; gamma - no mass and no charge (consists of energy)

It’s not exactly correct because a beta particle has the (small) mass of an electron (also the positron). All other choices are way off, I’d go with this one.

An alpha particle consists of two protons and two neutrons with a mass of 6.64 x 1027 kg and charge 3.2 x 10-19 C. If two of the
Dafna11 [192]

Answer:  ratio = 3.14 × 10³⁵

Explanation:

From Newtons law of Universal Gravitation;

Every object in the universe is attracted to every other object

F = (Gm₁m₂)/r²

G = 6.67 X 10⁻¹¹ N-m²/kg²

M₁= mass of one object

M₂= mass of second object

r = distance from center of objects

q = charge = 3.2 x 10⁻¹⁹C.

  • Calculating the gravitational force;

Fg = (Gm₁m₂)/r² = (Gm²)/r²

which is = (6.67×10⁻¹¹ × (6.64×10⁻²⁷)²) / r²

= (2.94 × 10⁻⁶³) / r²

  • Calculating the electric force;

Fe = (Kq₁q₂) / r² = K q² / r² = (9×10⁹ × (3.2 × 10⁻¹⁹)² / r²

Fe = 9.22 × 10⁻²⁸ / r²

comparing the ratio of both forces we have;

Fe/Fg = (9.22×10⁻²⁸/r²) ÷ (2.94×10⁻⁶³/r²)

r² cancels from the above expression, which gives;

ratio as 3.14 × 10³⁵

1. Which segment on this position vs time graph represents the object returning back to the origin?
Monica [59]

9514 1404 393

Answer:

  D. Segment D

Explanation:

The origin is represented on the graph by the position (y-value) being 0. The portion of the graph that shows position being non-zero and ending at 0 is the portion marked <em>segment D</em>.
