The observer can conclude that the sound is moving away from them and that its speed is increasing.
Intermolecular forces in water are greater than those in wood. APEX
Answer: a) 12857.1 m/s/s b) 578.6 N
Explanation:
Impulse = change in momentum
Ft = mV2 - mV1
V = AT, 45 / .0035 = 12857.1 m/s/s
(b) .045 x 12857.1 = 578.6 N
The force of gravity between two objects is:
F = G*m1*m2/r^2
So, it is dependent of the two masses and the distance between their centers of mass.
Both matter and light have been demonstrated to exhibit wave-like and particle-like behavior.
Light as a wave: light can diffract & refract
Light as a particle: photoelectric effect, Compton scattering
Matter as a wave: Davisson-Germer experiment
Matter as a particle: find a picture of any kinematics problem in a high school physics textbook
