Higher frequency for lower wavelength...
.... If speed is fixed. ie no medium change.
Steel is the correct answer because steel when on being applied heat will either change its state that too after hours because of its melting point being high or remain in that position only whereas wood turns into ashes...that is why we use metal utensils in the kitchen
D When it is stretched ready to shoot at the wall
Current<span> is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. ... Physicists consider </span>current<span> to flow from relatively positive points to relatively negative points; this is called conventional </span>current<span> or Franklin </span>current. Electrons, the most common charge carriers, are negatively charged.
Voltage<span> is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as "electric potential", which then must be distinguished from electric potential energy by noting that the "potential" is a "per-unit-charge" quantity.</span>
The electrical resistance<span> of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it: If the </span>resistance<span> is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.b
