Answer

Assuming

east is the positive x direction

north is the positive y direction

initial velocity , u = 19 j m/s

a) acceleration , a = 1.6 j m/s^2

Using first equation of motion

v = u + a × t

v = 19 + 5.6× 1.6

v = 28 j m/s

the velocity of the car after 5.6 s is 28 m/s north

b)

acceleration , a = -1.5 j m/s^2

Using first equation of motion

v = u + a × t

v = 19 - 5.6 ×1.5

v = 10.6 j m/s

the velocity of the car after 5.6 s is 10.6 m/s north

The elements selenium and oxygen are both poor electrical conductors. In which section of the periodic table are they
murzikaleks [220]

Answer:

The answer to your question is Nonmetals

Explanation:

Nonmetals   they are bad conductors of heat and electricity except graphite.

Metalloids   they are less conductors of electricity than metals.

Noble gases  they conduct electricity.

Halogens they are not metals and do not conduct electricity.

From this information, we conclude that Oxygen and Selenium are nonmetals.
