Answer:
Explanation:
The magnitude of electric field = 8 x 10⁴ V /m
there is a potential difference of 8 x 10⁴ V on a separation of 1 m
so on a separation of .5 m , potential drop or change in potential will be equal to
.5 x 8 x 10⁴
= 4 x 10⁴ V .
The increase in kinetic energy of proton = V X Q
V is potential drop x Q is charge on proton
= 4 x 10⁴ x 1.6 x 10⁻¹⁹
= 6.4 x 10⁻¹⁵ J
potential energy of the proton-field system will be correspondingly decreased by the same amount or by an amount of
- 6.4 x 10⁻¹⁵ J .
Answer:
This is a chemical property. If iron does rust, this is a slow chemical change since rust is an iron oxide with different properties than iron metal.
Answer:
Presiune = 350 N/m²
Explanation:
Având în vedere următoarele date;
Forța = 700 N
Suprafață = 2 m²
Pentru a găsi presiunea;
Matematic, presiunea este dată de formulă;
Presiune = forță/zonă
Înlocuind în formulă, avem;
Presiune = 700/2
Presiune = 350 N/m²
Explanation:
Measurement plays an important role in our daily lives because they are useful to do basic tasks, such as taking the temperature of a child with the help of a thermometer,making time estimations,measure out medicines and find out weights, areas and volumes of different substances
