Rust is a chemical change. Chemical changes are when the substances that make up an object change into other chemicals. For example, rust. What happens is metal and oxygen/water react and create rust. Hope this helps :)
Answer:
I say vehicle one, because both will apply the same amount of force but, because vehicle two has less mass, it will accelerate more rather than vehicle one which will accelerate less.
Answer:
K.E = 1.6 x 10⁻¹⁸ J
Explanation:
given,
thickness between two plate = t = 0.1 mm
Voltage difference between two plate = 10 V
charge of proton = q = 1.6 x 10⁻¹⁹ C
When the charge moves from positive to negative the potential energy reduces to kinetic energy
K.E = Δ PE
K.E = q Δ V
K.E = 1.6 x 10⁻¹⁹ x 10
K.E = 1.6 x 10⁻¹⁸ J
so, the kinetic energy of the proton when it reaches negative plate is equal to K.E = 1.6 x 10⁻¹⁸ J
