Answer from: vanessa8527

All the above properties are the physical properties of non metals.

Explanation:

The elements in the periodic table can be classified as metals, nonmetals and metalloids based on their physical and chemical properties. The nonmetals are basically the elements present in the chalcogenides groups such as oxygen, nitrogen, chlorine, fluorine etc.

For the most part, the nonmetals exist in solid and gaseous stage just with the exception of bromine which is a fluid nonmetal at room temperature. A portion of the nonmetals can likewise exist in the strong state yet those solids will be weak in nature.

So every one of the alternatives is coordinating with the physical properties of nonmetals.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
