Help = brainlist please

(a) Waves P and Q have the same frequency, but wave P has twice the wavelength of wave Q

(b) Waves Q and R have the same wavelength, but wave R has twice the frequency of wave Q.

(c) Wave T shows a steady frequency but changing amplitude

(d) Wave S shows a steady amplitude but changing frequency

(e) Waves Q and R have a low amplitude and a steady frequency

HOPE THESE ARE RIGHT

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
