Suppose a free-fall ride at an amusement park starts at rest and is in free fall. What is the velocity of the ride after 2.3 s?
horsena [70]

Answer:

V = a * t = 9.8 m/s^2 * 2.3 s = 22.5 m/s   velocity after 2.3 s

S = 1/2 g t^2      since initial speed is zero

S = 1/2 * 9.8 m/s^2 * 5.29 s^2 = 25.9 m

Which of the following compounds is not likely to have ionic bonds? Question 5 options: LiF NaCl CH4 MgF2
Harrizon [31]

Answer:

CH4

Explanation:

CH4 is joined together by a covalent bond, aka a bond between two non-metals. Non-metals are found on the right side of the periodic table and include Carbon (C) and Hydrogen. Although Hydrogen is technically on the left side of the table, it has the characteristics of a non-metal. Futhermore, Ionic bonds generally are between an element on the right joined with an element on the left. This is because ionic bonds want charges that will cancel out to create a neutral molecule.

example: LiF

Li→ Li+

F→F-

(Li+)+(F-)=charges cancel out.

Calculate the resistance of an electric bulb which allows a 10 A current when connected to a 220 V power source
kodGreya [7K]

Resistance can be calculated by Ohm's law

As per ohm's law we will have

V = i * R

here we will have

voltage = 220 volts

current = 10 A

So by the above formula we will have

220 = 10* R

R = 22 ohm

So resistance of the bulb is 22 ohm.
