Answer:

B - a simple circuit with one bulb and two batteries.

The circuit that would glow brightest is b - A simple circuit with one bulb and two batteries

This is the path for transmitting current. It usually consists of an electrical energy source and an electrical load.

In any circuit, the electrical power available is determined by the number of batteries available (energy source) and thus the current.

Since we know according to Ohm's law V = iR where

So, making i subject of the formula, we have i = V/R .

So, i ∝ 1/R this shows that the current is inversely proportional to the load.

So, the circuit that would glow brightest is b - A simple circuit with one bulb and two batteries

Answer:

Due to suffocation and toxic paint.

Explanation:

The population of hermit crabs has been decreasing because of suffocation and poison. Many crabs actually die slowly from suffocation because their gills require high humidity in order to breathe properly. Hermit crabs are slowly poisoned by tap water in which the toxic substances present in the paint that dissolves their shells that leads to the death of hermit crabs.

The heat is then transferred to water from the burned cake. The temperature difference is being used to calculate the heat energy of the cookie. Transfer of energy is the move in energy from place to place. Whereas the total quantity of energy may well be moved or converted – it is named energy preservation – does not change.

Answer:

wave

Explanation:

A wave is defined as the disturbance that causes the movement of energy. The energy is transferred as the waves move from one place to another. A medium is required for the transfer of energy. Usually a wave travels through air or water. The process is carried on at a specific speed that is termed as the speed of propagation.

Answer:

unbalanced force

Explanation:

According to Newton the determining factor on if and how an object will move is the unbalanced force acting upon that object. In Newton's first law he states that an object will remain at rest unless acted on by an unbalanced force. This unbalanced force needs to be stronger than any opposite force being acted upon by the same object. Enough so that the object exits its state of rest and begins moving in the direction in which the force is being applied. If the force is not strong enough to overcome the opposite forces then the object will not move.

Explanation:

Answer:

As the phase changes occur, the freedom of motion of the particles increases

Explanation:

In thermodynamics the state of matter: solid, liquid and gaseous.

We can characterize them, the solid state maintains a certain shape, which is why particles are tightly bound and can hardly move from their equilibrium positions.

The liquid state does not hold its shape, so the particles have more energy and can move a lot from their equilibrium position.

The gaseous state does not maintain the shape or the volume, so the interaction between the particles is very small, so they can move almost freely.

When examining the answer, the correct one is: As the phase changes occur, the freedom of motion of the particles increases.

When 70 Newton dog ran across the yard. we know The dog's weight. Hence option B is correct.

Force(F) applied on the body is mass(m) times its acceleration(a). i.e. F=ma according to this equation we get acceleration as a = this equation says that when we apply more force to the body, more acceleration it gets. When more is the mass of the body, greater force is needed to accelerate with same amount to that less mass.

70N dog means it is his weight, from which we can calculate its mass, by relation F = mg where g is acceleration due to gravity.

Hence for objective option B is correct, and for MSQ Both B and C is correct.

Explanation:

i think this is the ans

Answer:

The answer is "Including all three studies of 0s to 2s, that shift in momentum is equal".

Explanation:

Its shift in momentum doesn't really depend on the magnitude of its cars since the forces or time are similar throughout all vehicles.

Let's look at the speed of the car

[tex]F = m a\\\\a =\frac{F}{m}[/tex]

We use movies and find lips

[tex]\to v = v_0 + a t\\\\\to v = v_0 + (\frac{F}{m}) t[/tex]

The moment is defined by

[tex]\to p = m v[/tex]

The moment change

[tex]\Delta p = m v - m v_0[/tex]

Let's replace the speeds in this equation

[tex]\Delta p = m (v_0 + \frac{F}{m t}) - m v_0\\\\\Delta p = m v_0 + F t - m v_0\\\\\Delta p = F t[/tex]

They see that shift is not directly proportional to the mass of cars since the force and time were the same across all cars.

Answer:

Calor absorbido, Q = 52325 Joules

Explanation:

Dados los siguientes datos;

Masa = 250g to kg = 250/1000 = 0.25kg

Temperatura inicial, T1 = 10°C to Kelvin = 273 + 10 = 283K

Temperatura final, T2 = 60°C to Kelvin = 273 + 60 = 333K

Capacidad calorífica específica = 4186 j/kg.K.

Para encontrar la cantidad de calor necesaria;

La capacidad calorífica viene dada por la fórmula;

[tex] Q = mct [/tex]

Dónde;

Q representa la capacidad calorífica o la cantidad de calor.

m representa la masa de un objeto.

c representa la capacidad calorífica específica del agua.

dt representa el cambio de temperatura.

dt = T2 - T1

dt = 333 - 283

dt = 50 K

Sustituyendo en la fórmula, tenemos;

[tex] Q = 0.25*4186*50[/tex]

[tex] Q = 52325 [/tex]

Calor absorbido, Q = 52325 Joules

Momento = 170.8 Kgm/s

Explanation:

Dados los siguientes datos;

Masa = 3,05 kg

Velocidad = 56 m/s

Para encontrar el impulso;

El momento se puede definir como la multiplicación (producto) de la masa que posee un objeto y su velocidad. El momento se considera una cantidad vectorial porque tiene magnitud y dirección.

Matemáticamente, el momento viene dado por la fórmula;

[tex] Momento = masa * velocidad [/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Momento = 3.05 * 56 [/tex]

Momento = 170.8 Kgm/s

Answer:

8173.8 km

Explanation:

Fg=G(M*m/r^2)

r=sqrt(G*M*m/Fg)

G=6.6743*10^-11

M(earth)=5.972*10^24kg

M(object)=352kg

Fg=-2100N

r=sqrt((6.6743*10^-11)*(5.972*10^24kg)*(352)/-2100)

r=8173808m

r=8173.8km

According to Newton's calculations, gravity reduces to a fourth of what it was at the surface of the Earth if the distance from the planet's centre is doubled. At the Earth's surface, a satellite with a mass of 1,000 kg exerts a weight force of 9,800 N.

Satellites are pulled toward Earth by its gravity, even when they are hundreds of kilometres distant. The satellite doesn't fall back to Earth; instead, it travels into orbit above it due to gravity and the velocity it acquired during launch into space.

A satellite that is in a steady circular orbit around the Earth is always falling. It encounters a gravitational pull toward the centre of Earth as it orbits, which forces it to shift course and “fall” towards Earth.

Therefore, Since gravity is the only force acting on a satellite in circular orbit, the centripetal force and gravity must be equal: Fc = Fg.
