An electric iron operating at 120 volts draws 10. amperes of current. how much heat energy
faltersainse [42]
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.

A cat is moving at 18 m/s when it accelerates for 2 seconds. What is its acceleration?
vova2212 [387]

Answer: acceleration:4 m/s^{2}

              velocity: 26 m/s

Explanation:

The complete question is written bellow:

<em>A cat is moving at 18 m/s when it accelerates at </em>4 m/s^{2}<em> for 2 seconds. What is his new velocity?  </em>

<em />

In this situation the following equation will be useful:

V=V_{o}+at

Where:

V is the cat’s final velocity (new velocity)

V_{o}=18 m/s is the cat’s initial velocity

a=4 m/s^{2} is the cat's acceleration

t=2 s is the time

Solving the equation:

V=18 m/s+(4 m/s^{2})(2 s)

V=26 m/s This is the cat's new velocity
