Answer:
P.E = 25.48 Joule
Explanation:
Here,
mass (m) = 2kg
height (h) = 1.3m
g = 9.8m/s^2
P.E = mgh
= (2) (9.8) (1.3)
P.E = 25.48 Joule
Thus, the potential energy of a 2kg plant that is on a windowsill 1.3m high is 25.48 Joule

<h2>mass = 25kg</h2><h2>---------------------------------</h2>
force = 75N --- (<em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em>)</em>
acceleration = 3m/s² ---- (<em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em>)</em>
<h3>FORCE = mass × acceleration</h3>
75N = mass × 3m/s²
mass = 75÷3

Answer: Tech A is correct
Explanation:
Every vehicle has ignition system and without this system,it will not work. The battery of everything vehicle contain energy that start the vehicle and ignore it to start working. Electrical current move from the vehicle's battery and get to the induction coil, the induction coil increases the voltage in it so that the plug will be ignited. The spark plugs produce fire. The spark plug is connected to the ignition system. Once voltage is produced from the induction coil, electrical impulses move from induction coil to insulated plug wires. The spark plug need a very high voltage from the small voltage battery. Once the high voltage exceed the dielectric strength of the gases, spark jump the gap between the plug's fire end.
I think its friction and gravity change the motion hope this helps :)
