Question

If y=kxy = kx and someone changes the unit of xx such that: x′=$$2xx^{\prime}=2x$$, how must kk change such that yy will represent the same physical quantity in the new units of measurement?

Accepted Answer

kk must be halved

Answer

kk becomes k24\frac{$$k^2$$}{4}

Answer

kk must be doubled

Answer

kk remains unchanged

If y=kxy = kx and someone changes the unit of xx such that: x′=2xx^{\(\prime\)}=2x, how must kk change such that yy will represent the same physical quantity in the new units of measurement?

If $y = k x$ and someone changes the unit of $x$ such that: $x prime equals 2 x$ , how must $k$ change such that $y$ will represent the same physical quantity in the new units of measurement?
