For example, if a buyer obtains a seven-year balloon mortgage to purchase a home, he has seven years of equal monthly payments at a fixed interest rate. This rate is often lower than what the buyer would otherwise be able to secure under a traditional mortgage loan.
When sound reflects off a special curved surface called a parabola, it will bounce out in a straight line no matter where it originally hits. Many stages are designed as parabolas so the sound will go directly into the audience, instead of bouncing around on stage.
These different points include the blast wave, shock waves, fragmentation, heat and the blast wind. 1  Blast wave: When a bomb explodes, the area around the explosion becomes overpressurized, resulting in highly compressed air particles that travel faster than the speed of sound. This initial blast wave inflicts the most damage. 2  When this blast wave reaches a structure or person, two things will initially happen. 3  First, the person will feel the force of the blast, which is the primary and initial impact of the shockwave. 4  This will damage a structure or body on impact.
