C. Figure 11 and figure 1v are both compounds
Answer:
Thus, the initial velocity of the bullet is 507.5 m/s.
Explanation:
mass of bullet, m = 0.0085 kg
mass of block, M = 0.99 kg
Height raised, h = 0.95 m
Let the initial velocity of bullet is u and the final velocity of block and bullet system is v.
Use conservation of energy
Potential energy of bullet bock system = kinetic energy of bullet block system
Now use conservation of linear momentum
mu = (M+m) v
0.0085 x u = (0.99 + 0.0085) x 4.32
0.0085 u = 4.314
u = 507.5 m/s
Thus, the initial velocity of the bullet is 507.5 m/s.
B.The wave will bend or defract
diffraction is the phenomenon of bending of waves around the edge of the obstruction in its path of motion. this happens more strongly when the dimensions of the slit is comparable with the wavelength of the wavelength undergoing the diffraction process. hence the correct choice would be B
The various properties of electromagnetic waves and sound waves are described below. Sound Waves: Sound waves are mechanical<span> waves generated from vibrations within a medium. Sound can exist as longitudinal </span>mechanical<span> waves, which are also known as compression waves.</span>
