What is the current through resistor #1? (must include unit - A)

Answer:

the nucleus of the atom you have conserved almost all its mass in a very small volume

Explanation:

In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.

The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,

          V_atom / V_nucleo = 10⁴

Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.

In summary, the phrase that describes the process is:

  the nucleus of the atom you have conserved almost all its mass in a very small volume

Answer:D

Explanation:

The force of gravity from Mars will pull on the space probe the same amount no matter how far away it is​, so option D is correct.

All material objects in the universe are subject to the force of gravity, also known as gravitation. The force of gravity tends to draw any two non-zero mass objects or particles toward one another. Subatomic particles and galaxy clusters are both affected by gravity, as are objects of all sizes.

Due to the law of gravity, or gravitation, which draws all objects with mass in its vicinity toward it, Mars' gravitation is a natural occurrence. Due to the planet's lesser mass, its gravity is weaker than that of Earth. On Mars, the gravitational acceleration fluctuates, but on average it is 3.72076 m/ s² (or around 38% of Earth's).

Therefore, the force of gravity from Mars will pull on the space probe the same amount no matter how far away it is​.

Answer:A

Explanation:I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance.

They point away from the north pole and towards the south pole, is the statement correctly describing magnetic field lines around a bar magnet.

A bar magnet is a rectangular section of an item that has permanent magnetic qualities and is made of iron, steel, or any other ferromagnetic material or ferromagnetic composite.

It has two poles, one north, and one south, and when hanging freely, the magnet aligns itself such that the north pole faces the earth's magnetic north pole.

They point away from the north pole and towards the south pole, the statement correctly describes magnetic field lines around a bar magnet.

Hence statement B correctly describes magnetic field lines around a bar magnet.

Answer:

(a) k = 80 N/m   (b) x = 75 cm

Explanation:

The question says that, "A spring is elongated 30 centimeters when we exert a force of 24 N on it a) calculate the value of the spring constant b) calculate the elongation of the spring when applying a force of 60 N"

Given that,

Force exerted on the spring, F = 24 N

Elongation in the spring, k = 30 cm =0.3 m

(a) We know that, the force on the spring is given by :

F = kx

Where

k is spring constant

So,

[tex]k=\dfrac{F}{x}\\\\k=\dfrac{24}{0.3}\\\\k=80\ N/m[/tex]

(b) When F = 60 N,

[tex]x=\dfrac{F}{k}\\\\x=\dfrac{60}{80}\\\\x=0.75\ m\\\\x=75\ cm[/tex]

Hence, this is the required solution.

Answer:

Net force = 250 N

Explanation:

Given that,

The mass of a teacher, m = 75 kg

As the parachute opens, the system experiences a 1000N drag.

We need to find the magnitude of net force acting on the teacher. 2 forces are acting on her i.e. drag force and weight.

Net force,

F = mg-D

= 75(10)-1000

= -250 N

Hence, the net force is 250 N and it is acting in the upward direction.

Answer:

1.65 atm

Explanation:

Applying,

PV = nRT....................... Equation 1

Where P = Pressure, V = Volume, n = number of moles, R = malar gas constant, T = Temperature.

Make P the subject of the equation

P = nRT/V..................... Equation 2

From the question,

Given: n = 3.27 moles, V = 50.0 L, T = 35 °C = (273+35) = 308K

Constant: R = 0.082L.atm/K.mol

Substitute these values into equation 2

P = 3.27(0.082)(308)/(50)

P = 1.65 atm

Answer:

Radioactive decay: is the process by which an unstable atomic nucleus loses energy by radiation.

Half-life: in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half.

Radiometric dating: is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

Answer:

1.) The 1ˢᵗ three term is (-32), (-7) and 18

2.) The 1ˢᵗ three term is 127, 106 and 85

Step-by-step explanation:

Here,

First Term = a₁ = - 32

Common Difference = (d) = 25

Now, For 1ˢᵗ three term,

n = 1

a₁ = - 32

n = 2

aₙ = a + (n - 1)d

a₂ = (-32) + (2 - 1) × 25

a₂ = (-32) + 1 × 25

a₂ = (-32) + 25

a₂ = -7

n = 3

aₙ = a + (n - 1)d

a₃ = (-32) + (3 - 1) × 25

a₃ = (-32) + 2 × 25

a₃ = (-32) + 50

a₃ = 18

Thus, The 1ˢᵗ three term is (-32), (-7) and 18

Here,

First Term = a₁ = 127

Common Difference = (d) = -21

Now, For 1ˢᵗ three term,

n = 1

a₁ = 127

n = 2

aₙ = a + (n - 1)d

a₂ = 127 + (2 - 1) × (-21)

a₂ = 127 + 1 × (-21)

a₂ = 127 - 21

a₂ = 106

n = 3

aₙ = a + (n - 1)d

a₃ = 127 + (3 - 1) × (-21)

a₃ = 127 + 2 × (-21)

a₃ = 127 - 42

a₃ = 85

Thus, The 1ˢᵗ three term is 127, 106 and 85

Answer:

It will be the second one.

Explanation:

The reason it is the second one is because it is bound by two spherical surfaces bulging outwards. The second is doing just that.

A convex lens is shaped like two half circles, with a thin edge and a thick centre. The second lens is a convex lens.

A convex lens has a thin edge and a thick centre and is shaped like two half circles. Convex lenses are converging and can produce virtual and real images. Light is bent inward by a converging lens, causing light rays to collide and form an image.

The convex lens is a lens that converges light rays that are parallel to its principal axis (i.e. converges incident rays towards the principal axis) and is relatively thick in the centre and thin at the lower and upper edges.

The edges are curved outward, not inward. It is used in front of the eye to sharply bend incoming light, causing the focal point to shorten and the light to focus properly on the retina.

Complete question is;

Selena drew a diagram to show how current moves in a loop of wire that is placed between two magnets. At top left a piece of magnet labeled N and at top right a piece labeled S. Between these a square coil of wire with green arrows at its ends away from the magnets pointing away from the magnets. Red arrows point from N to S. Which best explains how Selena can correct her error?

A) She can change the magnets so like poles are facing each other.

B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.

C) She can change the arrows so they show the magnetic field reversing direction between the magnets.

D) She can change the magnetic poles so they are both on one side of the loop.

Answer:

B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.

Explanation:

Since the direction of the arrows point north and south whereas the magnets are east and west, it means the arrows are not pointing in the correct direction. To correct it she will have to make sure the arrows are pointing in opposite directions of the magnet via the sides of the loop.
