Hybrid

<u>Hybrid</u> modified the concept by adding an internal combustion engine and marketing hybrids that were part electric and part gas powered.

  • The driving wheels of hybrid vehicles receive power from their drivetrains.
  • A hybrid car has numerous sources of propulsion.
  • There are numerous hybrid configurations.
  • A hybrid vehicle might, for instance, get its energy from burning gasoline while alternating between an electric motor and a combustion engine.
  • Although they have primarily been employed for rail locomotives, electrical vehicles have a long history of integrating internal combustion and electrical transmission, like in a diesel-electric power-train.
  • Because the electric drive transmission directly substitutes the mechanical gearbox rather than serving as an additional source of motive power, a diesel-electric powertrain does not meet the definition of a hybrid.
  • Only the electric/ICE hybrid car type was readily accessible on the market as of 2017.
  • One type used parallel operation to power both motors at the same time.
  • Another ran in series, using one source to supply power solely and the other to supply electricity.
  • Either source may act as the main driving force, with the other source serving to strengthen the main.

A satellite is orbiting Earth with a distance R = 2REarth from Earth's center. If the satellite is moved to a distance R = 4REar
Maslowich

Answer:

Half

Explanation:

Given that:

  • radial distance of satellite from the earth, R=2R_E

Now, if the satellite is moved to a distance R=4R_E

<u>We  have the mathematical expression for the potential energy fue to gravitational field as:</u>

U=\frac{G.M.m}{R} ...................(1)

where:

G = 6.67\times 10^{-11}\ m^3.kg^{-1}.s^{2}

M = mass of earth

m = mass of satellite

R = radial distance of satellite

<u>Now from eq. (1) initially we have:</u>

U=\frac{G.M.m}{2R_E}

<u>after the satellite is moved, we have:</u>

U'=\frac{G.M.m}{4R_E}

\Rightarrow U'=\frac{G.M.m}{2(2R_E)}

\Rightarrow U'=\frac{1}{2} \times U

which is half of the initial condition.

Calculate the specific heat of a metal from the following data. A container made of the metal has a mass of 3.8 kg and contains
OLEGan [10]

Answer:

C = 771.35 J/kg°C

Explanation:

Here, e consider the conservation of energy equation. The conservation of energy principle states that:

Heat Given by Metal Piece = Heat Absorbed by Water + Heat Absorbed by Container

Since,

Heat Given or Absorbed by a material = m C ΔT

Therefore,

m₁CΔT₁ = m₂CΔT₂ + m₃C₃ΔT₃

where,

m₁ = Mass of Metal Piece = 2.3 kg

C = Specific Heat of Metal = ?

ΔT₁ = Change in temperature of metal piece = 165°C - 18°C = 147°C

m₂ = Mass of Metal Container = 3.8 kg

ΔT₂ = Change in temperature of metal piece = 18°C - 15°C = 3°C

m₃ = Mass of Water = 20 kg

C₃ = Specific Heat of Water = 4200 J/kg°C

ΔT₃ = Change in temperature of water = 18°C - 15°C = 3°C

Therefore,

(2.3 kg)(C)(147°C) = (3.8 kg)(C)(3°C) + (20 kg)(4186 J/kg°C)(3°C)

C[(2.3 kg)(147°C) - (3.8 kg)(3°C)] = 252000 J

C = 252000 J/326.7 kg°C

<u>C = 771.35 J/kg°C</u>

When conduction electrons pass through a device with resistance, which describes their energy?
Aleksandr-060686 [28]

Answer:

a) their potential energy increases.

Explanation:

Ohm's Law is

R= V/I

Where R= Resistance

V= potential difference or potential energy

I= current or conduction electron flow rate

Clearly R and V are directly proportional i-e Potential energy increases with resistance.

the presence of which magnetic feature best explains why a magnet can act a distance on other magnets or on objects containing c
katen-ka-za [31]

Magnetic fields

Explanation:

The presence of magnetic fields  best explains why a magnet can act a distance on other magnets or on objects containing certain metals.

  • Magnetic fields are lines of forces around a bar magnet.
  • These lines of forces attracts and repels other magnetic bodies and metallic bodies round it.
  • Magnetic lines of forces originates at the north pole and enters in the south pole.
  • Areas around a magnetic body are bounded by force fields.
  • A magnet has permanent magnetic fields round it.
