Answer:
c. No. An equation may have consistent units but still be numerically invaid.
Explanation:
For an equation to be corrected, it should have consistent units and also be numerically correct.
Most equation are of the form;
(Actual quantity) = (dimensionless constant) × (dimensionally correct quantity)
From the above, without the dimensionless constant the equation would be numerically wrong.
For example; Kinetic energy equation.
KE = 0.5(mv^2)
Without the dimensionless constant '0.5' the equation would be dimensionally correct but numerically wrong.
A change that would most improve his results would be; D) Connecting the galvanometer to the coil
' D ' is the only correct statement on the list.
Electromagnetic waves are capable of traveling through
many substances, and they're also capable of traveling
through vacuum. Mechanical waves can't travel in vacuum.
D) although recent research (1990's) has shown Uranus and Neptune to be ice giants and have heavier substances.
