TaigaYou can create a VB program to convert meters to centimeters by multiplying the meter value by 100. For example:
Dim meter As Double = 2.5
Dim centimeter As Double = meter * 100
MessageBox.Show(meter & " meters is equal to " & centimeter & " centimeters.")
This program declares a meter variable, converts it to centimeters by multiplying by 100, and displays the result using a message box.

Popquiz about current?
(Current-7)Current flows through a light bulb. Suppose a wire is connected across the bulb as shown. When this wire is connected...A: All the current continues to flow through the bulbB: Half the current flows through the bulb, half through the wireC: All the current flows through the wire.(Current-5)US Bulbs are rated for 120 V. European bulbs are designed for 240 V.If you buy a 100 W light bulb as a souvenir in Paris, and plug it in at home, what happens?A: It glows as usual, like a 100 W bulb should.B: Bzzzt, it burns out, too much powerC: It glows half as bright (powerful) as usualD: It glows 1/4 as bright as usualE: None of these/not enough info/don't know.(Current hmy-1)Electric companies generally tell their power customers the # of kilowatt-hours consumed in a month.What quantity is the power company telling you?A: power, duh!B: energy / timeC: timeD: energyE: None of these/impossible to determineF: current(Current_hmy-04)Rank in order, from largest to smallest, the powers dissipated in resistors a to d.R, DV+-R, 2DV+-2R, DV+-½ R, DV+-abcd1. a , b, c, d2. b, d, a, c3. b, c, a=d4. a=d, c, b5. b, d, b, c(Circuits-01)A battery with voltage ("emf") of 5V is attached to a resistor of resistance R.

Why Molecular bond Theory is better than Valence bond theory?
Molecular orbital theory is more recent than Valence bond theory. Both theories have their adherents and recently VB theory has had a renaissance. They both have their strengths. Chemists use both and mix/match. Some very familiar concepts used every day by chemists spring originally from VB theory, electronegativity, hybridisation of atomic orbitals. MO theory has its advocates, an early triumph was the prediction of the paramagnetism of O2 whereas valence bond theory predicted O2 to be diamagnetic. One criticism of VB theory is that it starts from a description of bonds as localised pairs of electrons, whereas in MO all bonds are potentially delocalised.
What is the resultant temperature when 2kg of water at 30degrees is mixed with 4kg of water at 90degrees?
The final temperature when mixing 2kg of water at 30°C with 4kg of water at 90°C can be calculated using the principle of conservation of energy. The formula Q1 + Q2 = m1c1(Tf - T1) + m2c2(Tf - T2) can be used, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, Tf is the final temperature, and T1 and T2 are the initial temperatures. By substituting the values into this formula, you can find the final temperature.
What chemical group does phosphate belong to?
The element P belongs to Group 15 (Vb), Nitrogen-Phosphorous- Arsenic group in the periodic table of elements.Phosphate is a weak, tri-basic anion PO43- but that's not a 'chemical group'.
What use your mother to separate mixtures?
Your mother may use methods like filtration, evaporation, distillation, or magnetism to separate different components in a mixture depending on their properties such as size, solubility, boiling point, or magnetic properties.
