Why is voltage considered to be a forcelike quantity how is it produced?

Voltage is the "force" that pushes the electrons or other charge carriers, producing a current. It should be noted that voltage does not have the units of force; thus, the traditional name "emf" (electromotive force) is misleading.

What quantity does the voltmeter measure when the switch is open?
Voltage
Is voltage a derived quantity?
Whether any quantity is a base quantity or a derived quantity depends on the definitions used in the system of measurements. In the SI, it is a derived quantity, defined as energy per unit charge. In units: joules/coulomb, where both joules and coulombs are also derived units.
Is voltage electrical pressure?
Yes. If you compare the effect water pressure has on flow rates and from an open tap, more pressure allows more water to flow out of and away from the source. In electrical circuitry, an increase in voltage - say from a battery - will in most cases enable a larger current to flow around the circuit that the battery is connected to. Voltage can be seen as the pressure force pushing another quantity around the loop and that quantity is electrical current . Electrical pressure and the quantity of electricity transmitted can be considered analogous to water flowing in pipes. Electrical pressure is called voltage: the longer the distances, the higher is the pressure (voltage) required to pump the current. That is why, for long distance transmission, high pressure (voltage here) is required, failing which, the power will not reach the destined end. It will dissipate on the way. <><><> We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.
Is reactance a scalar or a vector quantity?
In DC(direct current) circuits, voltage is scalar. But in the case of alternating-current(AC) voltage is vector quantity. It is because in an AC circuit the current is changing the direction for every time period. Therefore, since in this the direction matters its a vector quantity. Regards.
Disconnect a small voltage battery from a coil of many loops of wire and a large voltage is produced by?
The large collapse in the magnect field.
Voltage is a vector quantity or scaler quantity?
Scaler. Its vector counterpart is the electric field.
What quantity does the voltmeter measure when the switch is open?
Voltage
What is electrical pressure?
Electro motive force = EMF = Voltage.
What does it mean to say that current and voltage in a circuit are directly related?
It means that when one increases, the other increases as well. Also, it implies that this increase is proportional - if the voltage is doubled, the current will also double. Note 1: Normally, the voltage is considered the independent quantity; that's the quantity you can control directly. And if the voltage changes, so will the current. Note 2: In simple circuits, such as those that only have a voltage source and resistors, the relation will be a direct proportion. With electronic components, such as a transistor, the relationships can be more complicated.
What is relation between frequency and voltage of that frequency?
voltage and frequency both are different quantity.. don't mix it...
