Answer: Slope = - 1000.

Explanation:

The line of best fit of the graph will be linear.

The general linear equation can be expressed as;

Y = MX + C

Where the Y variable represents the volume in the experiment as dependent variable and the X represent the pressure as independent variable.

The equation can be rewritten as:

V = MP + C

Where C is the intercept.

Given that

V = 200, 100, 50, 25, 12.5 and

Pressure P = 0.1000, 0.2000, 0.4000, 0.8000, 1.6000

The slope M can be calculated by using the formula

M = (V2 - V1)/ (P2 - P1)

Where V1 = 200, V2 = 100, P1 = 0.1, P2 = 0.2

Substitute all the parameters into the formula

M =( 100 - 200)/ ( 0.2 - 0.1 )

M = -100/0.1

Slope M = - 1000

Answer: B) zero because both objects are at rest

Explanation:

Given the following :

Mass of anchor = 10kg

Mass of boat = 1000kg

Note : both boay and anchor are at rest, this gives a Velocity of zero

The momentum of a body is given as the product of Mass and velocity, that is,

Momentum = mass × velocity

Initial Momentum of anchor-boat system =

(mass of boat× initial velocity of boat) + (mass of anchor × initial velocity of anchor)

Initial Velocities of boat and anchor = 0

Therefore,

Initial momentum = (1000 × 0) + (10 × 0)

Initial momentum = (0 + 0) = 0

This is ecause both objects are at rest.

Answer:

If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit.

Explanation:

Leave any one of these things out and you will not have a complete circuit.

A complete electric circuit includes a voltage source, current, wires, and load to flow the current.

An electrical load can be described as an electrical component of a circuit that consumes electrical power such as electrical appliances, bulbs, and lights. The electrical load may also refer to the power consumed by a circuit. An electrical load is opposed to a power source, such as a battery, which produces power.

If an electric circuit contains an output port, a pair of terminals that generates an electrical signal, the circuit connected to this terminal is the load. Load influences the performance of circuits according to the output voltages or currents, such as voltage sources, and amplifiers.

Mains power outlets supply power at constant voltage, with electrical appliances connected to the power circuit making up the load. When a high-power device switches on, it drastically reduces the load impedance.

Answer:

[tex]\beta=B=8.05\mu T[/tex]

Explanation:

The density of the magnetic flux is given by the following formula:

[tex]\beta=\frac{\Phi_B}{A}=\frac{ABcos\theta}{A}=Bcos\theta[/tex]

The normal vector A and the vector of the magnitude of the magnetic field are perpendicular, then, the angle is zero:

The magnitude of the magnetic field is calculated by using the formula for B at a distance of x to a point in the plane of the loop:

[tex]B=\frac{\mu_oIR^2}{2(x^2+R^2)^{3/2}}[/tex]

For x = 0 you have:

[tex]B=\frac{\mu_oIR^2}{2R^3}=\frac{\mu_oI}{2R}[/tex]

R is the radius of the circular loop and its values is:

[tex]R=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{0.5m^2}{\pi}}=0.39m[/tex]

Then, you replace in the equation for B with mu_o = 4\pi*10^-7 T/A:

[tex]B=\frac{(4\pi*10^{-7}T/A)(5A)}{2(0.39m)}=8.05*10^{-6}T=8.05\mu T[/tex]

Answer

medium are much closer together

Explanation:

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

False, the process of converting a solid into liquid at its melting point is called melting.

What is fusion ?

When two light atoms combine to form a new heavier nucleus this process is known as fusion. For example, when two hydrogen atoms combine to form helium atom.

Upon reaching a substance's melting point, the heat supplied by the substance (latent heat of fusion) causes the molecules to drift apart and the substance changes state (solid to liquid) by increasing its internal energy, resulting in a temperature decrease and a change of state (solid to liquid).

COHETE.

[tex]F_{y}[/tex] = 700000 N(sen 90° - 20°) - 560000 N = 97785 N

The approximate vertical component of the net force that is propelling the rocket away from Earth is 112,000 N. Option B is correct.

The net force acting on the rocket is the sum of the thrust force and the weight of the rocket. The thrust force is pointing upwards at an angle of 20 degrees, and the weight of the rocket is pointing downwards. The thrust force is the force that is generated by the rocket engine. It is the force that propels the rocket upwards.

The weight of the rocket is the force of gravity acting on the rocket. It is the force that pulls the rocket downwards. The net force acting on the rocket is the sum of the thrust force and the weight of the rocket. If the net force is positive, the rocket will accelerate upwards. If the net force is negative, the rocket will accelerate downwards. If the net force is zero, the rocket will remain at rest.

net force = thrust force + weight

vertical component of net force = thrust force * cos(angle)

vertical component of net force = 700,000 N * cos(20 degrees) = 112,000 N. Option B is correct.

Answer:

318.3 nm

Explanation:

We approximate the circular film as a cylinder of height h and radius, r. Its volume V = πr²h. Since this volume equals the volume of the oil drop, the height of the circular film is thus h = V/πr²

V = 10⁻¹⁰ m³ and r = 10 m

Substituting into h, we have

h = 10⁻¹⁰ m³/π(10)²

= 0.3183 × 10⁻¹² m

= 3183 × 10⁻⁹ m

= 318.3 nm

Answer:

1) 916 kg/m³

2) 9.8566×10⁴ Pa

Explanation:

1) Originally, the water is at the same level on both sides.  When the oil is added, one side goes down 67.5 mm and the other side goes up 67.5 mm.  The top of the oil is 12.3 mm above the water, so the total height of the oil relative to the low end of the water is:

12.3 mm + 67.5 mm + 67.5 mm = 147.3 mm

And the height of the water relative to the low end is:

67.5 mm + 67.5 mm = 135 mm

The pressure at the bottom of the oil equals the pressure of the water at the same elevation.

P = P

ρgh = ρgh

ρh = ρh

ρ (147.3 mm) = (1000 kg/m³) (135 mm)

ρ = 916 kg/m³

2) P = ρgh

P = (1.3608×10⁴ kg/m³) (9.7835 m/s²) (0.74035 m)

P = 9.8566×10⁴ Pa

Ionizing radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized. ... Forms of electromagnetic radiation.

(from google)

thank you :)

Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized.

The process in which an electron is given enough energy to break away from an atom is called ionization.

This process results in the formation of two charged particles or ions:

Each ionization releases energy that is absorbed by material surrounding the ionized atom.

Ionizing radiation deposits a large amount of energy into a small area. In fact, the energy from one ionization is more than enough energy to disrupt the chemical bond between two carbon atoms.

There are three main kinds of ionizing radiation:

alpha particles, which include two protons and two neutrons

beta particles, which are essentially electrons

Therefore,

According to the definition of ionizing radiation,

Ionizing radiation can remove electrons from the atoms, i.e. It can ionize atoms.
