Answer:
100 cm
Explanation:
It is given that there are two loudspeakers that produces 
along x-axis.
The maximum intensity of the sound is 
at a distance of = 15 cm apart.
The sound intensity becomes zero when the separation between the speakers are increased and becomes 65 cm.
Therefore, the sound waves are in the phase, 
The sound waves are out of phase when 
Therefore,
= 2 (65 - 15)
= 2 x 50
= 100 cm
Hence the wavelength of the sound is 100 cm.
Answer:
a) (momentum of the elephant), p1 = 14625 kg×m/s
b) p1 = 609.4×p2
c) (momentum of the hunter), p3 = 720 kg×m/s.
Explanation:
a) if m = 1950 kg is the mass of the elephant and V = 7.50 m/s be the speed of the elephant, then the momentum is given by:
p1 = m×V = (1950)×(7.50) = 14625 kg×m/s
b) if m = 0.0400 kg is the mass of the bullet and v = 600 m/s be the speed of the bullet, then the momentum of the bullet is given by:
p2 = m×v = (0.0400)×(600) = 24 kg.m/s
then:
p1/p2 = (14625)/(24) = 609.4
that is, p1 = 609.4×p2
Therefore, the momentum of the elephant is 609.4 times the momentum of the bullet.
c) the momentum og the hunter after missing the elephant is given by:
p3 = m×v = (90.0)×(8) = 720 kg.m/s
Therefore, the momentum of the hunter is 720 kg×m/s.
Answer:
It has less mass than the car
Explanation:
Both car and bug have the same amount of force acting on them. As the bug mass is much smaller, it sees a greater acceleration
