Answer : Quantity or quality that varies like manipulating a variable to see what will happen to another variable
Answer:
Total resistance = 0.92Ω
Explanation:
For parallel connected resistors we have effective resistance
Here parallel circuit made up of resistances of 2Ω, 3Ω, and 4Ω.
That is
R₁ = 2Ω
R₂ = 3Ω
R₃ = 4Ω
Substituting
Total resistance = 0.92Ω
The direction of force, when electric current and magnetic field direction given is at 90° to the plane containing current I and Magnetic field B.
<h3>What is magnetic force?</h3>
The force of attraction or repulsion experienced by a magnetic material when it enters the magnetic field.
When a wire with an electric current I is placed in a magnetic field of strength B it experiences a magnetic force F.
According to the Fleming's right hand rule, the direction can be determined by knowing any two parameter's direction.
Thus, The direction of force is at 90° to the plane containing current I and Magnetic field B.

drumlins: egg-shaped hills
Explanation: APEX
Answer: Heat transfers through brick walls and glass through conduction. In conduction heat is transferred by vibration of molecules. most energetic molecules vibrate and pass on the energy to less energetic molecules. Then they vibrate and further pass on the energy. In this way heat is transferred out of the home. Heat also transfers through the leakage of warm air from doors and windows. This occurs through convection. In convection energy is transferred through bulk movement of liquid and air molecules. Heat also transfers from insulation. in insulation there is no material in between the layers. So heat transfer through insulation occurs through radiations that occurs by X-Rays, Ultravoilet rays etc.
