Answer:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object

Answer: Newton's second law states that acceleration of a particle is dependent on the forces acting upon the particle and the particle's mass.

Explanation: Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Resistance is seen as part of ______________--- how a person understands his or her being and relationship to the world at large
aleksley [76]

Answer:

The self and world construct

Explanation:

in physics

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Self psychology views resistances as protecting a vulnerable self. Resistances are seen as efforts to maintain levels of organization that patients have achieved within the context of their traumatic life situation.

Which property of X-rays allows them to enter our bodies and create pictures of our bones and other internal structures?
Degger [83]

Answer:

(A) Their high energy

Explanation:

The higher the energy of the x-ray the more "likely" they will pass through.

The x-ray is electromagnetic energy caused by energy changes in an electron.

X-ray are energetic and have enough energy to break up molecules. That is what reveals the bad or damaged cells in our body.

Select the properties that apply to superconductors.
makkiz [27]
made from pure metals . . . no;
they've been made from all kinds of weird compounds and alloys.
 
conduct electricity with zero resistance . . . yes;
that's why they're called "superconductors".

produce a strong magnetic field . . . possible, but not because it's a superconductor;
just like any other conductor, the magnetic field depends on the current that's flowing in the conductor.

no loss of energy in the transfer of electricity . . .
there's no loss of energy in the current flowing in the superconductor;
but if you tried to transfer the current out of the superconductor into
something else, then there would be some loss.

A paleontologist estimates that when a particular rock formed, it contained 12 mg of the radioactive isotope potassium-40, which
leva [86]

Answer:

t = 2.52 billion \:years

Explanation:

As we know by radioactivity law

N = N_o e^{-\lambda t}

so here we will have

N = 3 mg

N_o = 12 mg

now we will have

3 = 12 e^{-\lambda t}

\lambda t = ln 4

now we also know that

\lambda = \frac{ln2}{1.26 \times 10^6 yrs}

t = 1.26\times 10^6\times \frac{ln4}{ln2}

t = 2.52 billion \:years
