Describe the formation of both positive and negative ions

Physics
1 answer:
prisoha [69]3 years ago
8 0

Answer:

A positive ion is formed by the removal of electron(s) from an atom or group of atoms.

A negative ion is formed by the addition of electron(s) to an atom or group of atoms.

Explanation:

A positive ion, also known as cation is formed by the removal of electron(s) from an atom or group of atoms until there are fewer electrons than protons. It positive ion because it contains more proton than electron.

A negative ion, also known as anion is formed when an atom or group of atoms gains electron(s) until there are more electrons than protons. It negative ion because it contains more electron than proton.

Which statement describes a surface wave?
katen-ka-za [31]
A surface wave is a wave that travels along the surface of a medium. The medium is the matter through which the wave travels. Ocean waves are the best-known examples of surface waves. They travel on the surface of the water between the ocean and the air. (According to ck12.org)

So your answer would be A!

A catamaran with a mass of 5.44×10^3 kg is moving at 12 knots. How much work is required to increase the speed to 16 knots? (One
Andre45 [30]

The work that is required to increase the speed to 16 knots is 14,176.47 Joules

If a catamaran with a mass of 5.44×10^3 kg is moving at 12 knots, hence;

5.44×10^3 kg = 12 knots

For an increased speed to 16knots, we will have:

x = 16knots

Divide both expressions

\frac{5.44 \times 10^3}{x} = \frac{12}{16}\\12x = 16 \times 5.44 \times 10^3\\x = 7.23\times 10^3kg\\

To get the required work done, we will divide the mass by the speed of one knot to have:

w=\frac{7230}{0.51}\\w= 14,176.47Joules

Hence the work that is required to increase the speed to 16 knots is 14,176.47 Joules

The compressor on an air conditioner draws 66.1 a when it starts up. the start-up time is about 0.388 s. how much charge passes
Ierofanga [76]
The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:
I= \frac{Q}{\Delta t}
where Q is the charge and \Delta t is the time. Re-arranging the formula, we have
Q=I \Delta t

for the compressor in our problem, the intensity of current is I=66.1 A, while the time is \Delta t= 0.388 s, so the amount of charge that crosses a certain point of the circuit during this time is
Q=I \Delta t=(66.1 A)(0.388 s)=25.65 C

A spring with a mass on the end of it hangs in equilibrium a distance of 0.4200 m above the floor. The mass is pulled down a dis
den301095 [7]

Answer:

0.48 m

Explanation:

I'm assuming that this takes place in an ideal situation, where we neglect a host of factors such as friction, weight of the spring and others

If the mass is hanging from equilibrium at 0.42 m above the floor, from the question, and it is then pulled 0.06 m below that particular position. This pulling is a means of adding more energy into the spring, when it is released, the weight compresses the spring and equals its distance (i.e, 0.06 m) above the height.

0.42 m + 0.06 m = 0.48 m

At the highest point thus, the height is 0.48 m above the ground.
