The complete question is how much heat energy is delivered by the iron in 30 seconds.
Heat is given by IVt, Where I is the current in Amperes, V is the voltage, and t is the time in seconds,
Therefore; 
Heat energy = 120 × 10 ×30
                     = 36000 joules or 36 kJ
Heat energy is measured in joules.

Triss [41]

C. Clear, dry weather. A good way to remember is H for high pressure = H for happy weather; L for low pressure = L for lousy weather (Glad I had someone to tell me this)

A charged particle decelerates as it moves from location a to location b. if va = 160 v and vb = 100 v, what is the sign of the
skelet666 [1.2K]

The sign of the charged particle is positively charged.

<h3>What is potential difference?</h3>
  • When a single charge is transported in an electric field, work is done by the potential difference (also known as electrical potential).
  • There is potential energy stored in this charge that could flow when work is done on it.
  • Voltage is the possibility of a single charge flowing. The need to flow increases with voltage.
  • Here, voltage can be the potential differences.

The potential difference between the 2 points determines the movement of that particle. An electron moves from lower to higher potential which is negatively charged, and a positively charged particle moves  from higher to lower potential.

Now, since the particle is moving from a point A having 160 v potential to point B having 100 v potential that is it is moving from higher potential to a lower potential therefore the particle will be a positively charged one.

Which mathematical formula would you use to calculate the IMA of a wheel?
Crazy boy [7]
As shown in the figure, the ideal mechanical advantage is calculated by dividing the radius of the wheel by the radius of the axle. Any crank-operated device is an example of a wheel and axle. Force applied to a wheel exerts a force on its axle.
