A cell of emf 1.5v is connected in series with a resistor of resistance 3.0 ohms. A voltmeter connected across the cell registers 0.9v. Calculate the interval resistance of the cell

The upward force acting on the wing of a airplane in flight is known as the "lift" force. (d)

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !

Fb is the magnetic force  q is the chargev is the velocity of the charge  b is the magnetic field  the equation is: f=|q|vbsin0

The net force would equal 13 newtons , forward. the mass will accelerate. balanced forces: when forces are in balance, acceleration is zero. velocity is constant and there is no net or unbalanced force.hope this : )
