what is the unit for tension in SI base units
Kgms^-2
what is the unit for impulse in SI base units
kgms^-1
What best describes the newton
derived unit
how can you improve the procedure/ reduce uncertainty when using a metronome (or timing)
time from the midpoint, use a marker to determine the midpoint, time the number of oscillations and divide by the number of complete oscillations.
how can you reduce uncertainty when using measuring instruments
use instruments with a high resolution, use a wide range
what are the SI base quantities
length, time, amount of substance, electric current, luminous intensity, mass, temp
what are the SI base units
meter, second, mole, ampere, kilogram. kelvin, candela
what is newton in base units
Kgms^-2
what is the volt in Base SI units
kgm^2s^-3A^-1
what is resistance in base SI units
kgm^2s^-3A^-2
