The relation that satisfies the the dimensional analysis is 1[LT^{-1} ]= k[L^{p+q} T^{-2p}]

<em>Your velocity equation seems to be incorrectly typed, below is the equation is I presume you intended to type;</em>

v = kg^{p}h^{q}

The dimensional analysis of the velocity equation is calculated as follows;

v = kg^{p}h^{q}

where;

k, p and q are constant

h is the distance (m)

g is acceleration due to gravity (m/s²)

v is the velocity (m/s)

v = kg^ph^q\\\\LT^{-1} = k[LT^{-2}]^p[L]^q\\\\LT^{-1} = k[L^pT^{-2p}][L^q]\\\\1[LT^{-1} ]= k[L^{p+q} T^{-2p}]\\\\1 = k\\\\L^1 = L^{p+q} \\\\1 = p+q\\\\T^{-1}  = T^{-2p}\\\\

Thus, the relation that satisfies the the dimensional analysis is 1[LT^{-1} ]= k[L^{p+q} T^{-2p}]

When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy
babymother [125]

Answer:

TRUE

Explanation:

When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. The transformation happens when the magnetic field produced by the current causes the wire to move.
