According to Newton's 1st Law of Motion, a moving object will move forever at a constant rate in the same direction. Why do objects stop moving?
Please help!
Answer:
Object stop moving when the force which is friction that acts to resist sliding between two touch-ing surfaces is not present
Answer:
See below ~
Explanation:
Newton's 1st Law of Motion : "An object in motion (or rest) will stay in motion (or rest) unless acted upon by an unbalanced force.

A second-grade teacher dropped a box of paper clips and they scattered all over the floor. She then asked her students, "Why will a magnet be a useful tool to pick the paper clips?"
The magnet will be a useful tool to pick the paper clips because the magnet can attract the paper clips.
Attraction of magnetsThe like poles of magnets repel while unlike poles of magnets attracts. Magnets attracts irons or metallic materials.
The paper clips are mettalic or made of iron and hence the magnet will attract them.
There we can conclude that the magnet will be a useful tool to pick the paper clips because the magnet can attract the paper clips and will help to gather them together for easy picking.

how do two positive electric charges react to each other?
Answer:
The two positive electric charges repel each other. If a positive charge and a negative charge interact, their forces act in the same direction, from the positive to the negative charge. As a result opposite charges attract each other: The electric field and resulting forces produced by two electrical charges of opposite polarity.

A 3.0- resistor is connected in parallel with a 6.0- resistor. This combination is connected in series with a 4.0- resistor. The resistors are connected to a 12-volt battery. How much power is dissipated in the 3.0- resistor
Answer:
5.33 w
Explanation:
parallel resistors equivalent r = r1 r2 /(r1+r2) = 2 ohm
in series with 4 ohm resistor makes total r = 6 ohms
12 v / 6 ohm = 2 amps current
2/3 of the current will go through the 3 resistor
2/3 * 2 = 4/3 amp
power = I^2 R = 4/3 ^2 * 3 = 5.33 watts

For Acellus
Explanation:
The electric field equals the force exerted by the unit positive charge. The electric field at point P is 3.615×10⁶ N/C. Its unit is N/C.
What is an electric field?
When a charged particle is got influenced by another charged particle when bring near to it, a field is created by an electric charge. This field is called the electric field.
The electric field is obtained by taking the ratio between Force and unit positive charge. Force in a charge is because of attraction and repulsion. The SI unit of force is Newton (N).
The unit positive charge is the test charge used to analyze the other charges present in the field. The SI unit of charge is Coloumb (C). The charge is responsible for the creation of an electric field.
From the givens,
The charge q₁ = q₂ = 5×10⁻⁸ C,
The distance of charges from point P, r₁ = 0.424 m; r₂ = 0.636 m.
The net electric field E = E₁ + E₂
Electric field E = F / q
E₁ = kq₁ / r₁² (k = 9×10⁹ Nm²/C²)
= 9×10⁹× 5×10⁻⁸ / (0.424)²
E₁ = 2.503×10³ N/C.
E₂ = kq₂ / r₂²
= 9×10⁹× 5×10⁻⁸ / (0.636)²
E₂ = 1.112×10³ N/C
E = E₁ + E₂
=2.503×10³ + 1.112×10³
= 3.615×10³ N/C
Hence, the net electric field is 3.615×10³ N/C.

A spring hangs at rest from a support. If you suspend a 0.46 kg mass from the spring it elongates 0.79m.
A) Determine the spring constant.
B) Calculate the elongation if you put a .75kg mass on the spring.
a. The restoring force in the spring has magnitude
F[spring] = k (0.79 m)
which counters the weight of the mass,
F[weight] = (0.46 kg) g = 4.508 N
so that by Newton's second law,
F[spring] - F[weight] = 0 ⇒ k = (4.508 N) / (0.79 m) ≈ 5.7 N/m
b. Using the same equation as before, we now have
F[weight] = (0.75 kg) g = 7.35 N
so that
(5.7 N/m) x - 7.35 N = 0 ⇒ x = (7.35 N) / (5.7 N/m) ≈ 1.3 m

The radium isotope 223Ra, an alpha emitter, has a half-life of 11. 43 days. You happen to have a 1. 0 g cube of 223Ra, so you decide to use it to boil water for tea. You fill a well-insulated container with 460 mL of water at 16∘ and drop in the cube of radium
The time taken for the water to boil at the given rate of the alpha decay is 0.08 s.
Number of radium atom
The number of radium atom in 1.0 g is calculated as follows;
[tex]N = N_A(\frac{m}{M} )\\\\N = (6.02 \times 10^{23})(\frac{1}{223} )\\\\N = 2.7 \times 10^{21} \ atoms[/tex]
Decay constant of the radium[tex]\lambda = \frac{ln2}{t_{1/2}} \\\\\lambda = \frac{ln 2}{(11.43 \times 86400)} \\\\\lambda = 7.02 \times 10^{-7} \ s^{-1}[/tex]
Rate of the alpha decayR = λN
R = (7.02 x 10⁻⁷) x (2.7 x 10²¹)
R = 1.895 x 10¹⁵ atoms/s
Change in the mass of the RadiumΔm = m(Ra₂₂₃) - [m(Rn₂₁₉) + m(α)]
Δm = 223.018u - (219.008u + 4.0026u)
Δm = 0.0074u
Energy released in the alpha decay[tex]E =\Delta mc^2\\\\E = 0.0074u \times c^2\\\\E = 0.0074 \times931.5\ MeV/c^2 \times c^2\\\\E = 6.893 \ MeV\\\\E = 6.893 \times 10^6 \times 1.6\times 10^{-19} \\\\E= 1.103 \times 10^{-12} \ J[/tex]
Rate at which energy is releasedP = E/t = ER
P = (1.103 x 10⁻¹²)(1.895 x 10¹⁵)
P = 2,089.99 J/s
Mass of the boiled watermass = density x volume
mass = (1 g/L) x (0.46 L)
mass = 0.46 g
Heat absorbed by the waterQ = mcΔT
Q = 0.46 x 4.184 x (100 - 16)
Q = 161.67 J
Time taken for the water to boilPt = Q
t = Q/P
[tex]t = \frac{161.67}{2,089.99} \\\\t = 0.08 \ s[/tex]
Thus, the time taken for the water to boil at the given rate of the alpha decay is 0.08 s.
