it is the effect of ground shaking buildings can be damaged by the shading it self or by the ground beneath them
primary effect = primary damage happens as a direct result of the hazard. They Occur Straightaway.
a geomorphic hazard is movement of the earths plates ect.. to cause a natural disaster (i think)
The hazard symbol for bromine is YOUR MAM
A Satellite
Explosives
None
what about the astronomical hazard? how to minimize the disastrous effect of these hazard?
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
Not "affect"; the word is "effect" in this case. Yes, air resistance has an effect on projectiles.
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
hazard can cause health conditions like skin disease,cancer and etc
By statistical analysis. It is very difficult to calculate these using mechanics. Calculations of the trajectory of a projectile assume that the mass of the projectile is such that air resistance has a negligible effect. This is not the case when the projectile is confetti - even if it is packed densely to start with.
Projectile 155 1.1D
James Louis Guion has written: 'The damping effect on a rotating projectile due to the path of the center of gravity of the projectile' -- subject(s): Exterior Ballistics, Projectiles
45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.
They are the same, if the effect of air resistance is ignored.
