Answer:
Option A
,
Explanation:
When the ball its thrown up, at half way of its flight it means half of its vertical height which is 
.
potential energy = mgh
since it moved half way of height
P.E = 
This means for the body to have gained half of its P.E, it will loose half of its kinetic energy.
Final kinetic energy(
) = E/2
kinetic energy = 
let the final velocity at halfway flight be v1
= E/2
=
cross multiply we have
=
cancel m from both sides
= 
take the square root of both sides,
Thus our final velocities will be E/2 and 
Answer:
Based on the properties electrically charged particles, we have that unlike charges attract and like charges repel each other. In order for proper application of an electrostatically negatively charged paint to be properly applied on the metal body surface of a vehicle, require that for attraction, the surface of the vehicle should be grounded and positively charged so as to effectively attract the negatively charged paint particles as it exits the nozzle, to form a strong attachment with the positively charged surface of the vehicle
Explanation:
If a theory is studied in let's say the 17th century, the theory has had many years to be studied and explained by many different people many different ways.
Answer:
The answer is below
Explanation:
Una partícula efectúa un MAS cuya ecuación es: x=0.3cos (2t + π/6) m. Determinar: Amplitud, frecuencia angular, fase inicial, periodo, frecuencia de oscilación y posición en t=0.25 s
Solution:
La ecuación de la onda es:
x = A cos (ω t + Ф), donde:
A = amplitud, ω = frecuencia angular = 2 π / T = 2 π f, Ф = fase inicial, f = frecuencia, T = período
Por lo tanto, comparando la ecuación de la onda con x = 0.3cos (2t + π / 6), obtenemos:
a) A = 0.3
b) ω = 2 rad / s
c) Ф = π / 6 rad
d) ω = 2π / T
2 = 2π / T
T = 3.14 s
e) ω = 2πf
2 = 2πf
f = 0.32 Hz
f) en t = 0.25 s:
x (t) = 0.3cos (2 * 0.25 + π / 6) = 0.22 m
