Answer:
the speed of a jet plane = v = 12 m/s
Explanation:
jet plane that travels 48 meters East in 4 seconds?
<u>use the velocity as distance over time formula = v = d / t</u>
where:
t = 4 sec
d = 48 m
plugin values into the formula
v = <u> 48 m </u>
4 sec
v = 12 m/s
therefore,
the speed of a jet plane = v = 12 m/s
<span>We convert the Fahrenheit temperature to Celsius. C = F 32 F 5 C = 15 F 32 F 5 C = 26 C . The antifreeze only protects to 9 F 9 F 22 C and thus it will not offer protection to temperatures as low as 15 F = 26.1 C . 2A (E) The mass is the difference between the mass of the full and empty flask. density = 291.4 g 108.6 g = 1.46 g/mL 125 mL 2B (E) First determine the volume required. V = (1.000 × 103 g) (8.96 g cm-3) = 111.6 cm3. Next determine the radius using the relationship between volume of a sphere and radius. 4 4 111.6 3 r= 3 = 2.987 cm V = r3 = 111.6 cm3 = (3.1416)r3 3 3 4(3.1416) 3A (E) The volume of the stone is the difference between the level in the graduated cylinder with the stone present and with it absent. density = mass 28.4 g rock = = 2.76 g/mL = 2.76 g/cm3 volume 44.1 mL rock &water 33.8 mL water 3B (E) </span>
Covalent bonding occurs when pairs of electrons are shared by atoms.
Ionic bond.
In the ionic bond one atom loses one or more electrons, leaving the atom with positive charge, and the other atom accepts those electrons standing with negative charge.
