The force of gravity between two objects is directly proportional to which of the following? a. the masses of each object.
b. the velocity of each object.
c. the distance between the objects squared.
d. the mass of one object and the distance between the objects.

Answers

Answer 1
Answer: Force of gravity =Gxm1xm2 /r^2G= gravitational constantm1 and m2 are massesr is the distance between masses.So a is the correct option
Answer 2
Answer: The force of gravity between two objects is directly proportional to the
product of the two masses, and to the mass of each object individually.

An electron and a proton are confined in the same space. For what particle would a measurement of the speed have a greater uncertainty?

Answers


The electron is a subatomic particle, symbol e− or β−, with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum of a half-integer value in units of ħ, which means that it is a fermion. Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves, and so can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a higher De Broglie wavelength for typical energies. Hope this HELPS :D

How much force is needed to accelerate a 68 kilogram skier at a rate of 1.2m/sec

Answers


Let's use Newton's 2nd law of motion:

                                     Force = (mass) x (acceleration)

                                     Force = (68 kg) x (1.2 m/s²) =  81.6 newtons .
f=m*a

68*1.2=81.6

f=81.6

This exists in the space surrounding a charged particle and exerts a force on other charged particles.

Answers

Gravitational field exists in the space surrounding a charged particle and exerts a force on other charged particles. Gravitational waves are ripples of waves travelling outward from the source. The more massive the orbit of two bodies, the more it emits gravitational wave. And everything around it that is near within the wave experiences a ‘pull’ toward the orbiting bodies.
