Answer:
0.018 J
Explanation:
The work required to bring the charge from infinity to the point P is equal to the change in its electric potential energy. This can be expressed as
where
represents the charge's magnitude
and signifies the potential difference between point P and infinity.
After substituting into the formula, we arrive at
Respuesta:
11.4 m/s
Explicación:
La fórmula para la aceleración centrípeta es:
donde, a es la aceleración, v la velocidad alrededor de la circunferencia y R el radio del círculo.
En este problema,
a = g = aceleración debida a la gravedad en la cima =
v = ?
R = 13.2 m
Por lo tanto,
v = 11.4 m/s
Answer:
(a). The distance traveled is 7.06 km towards the west.
(b). Their displacement magnitude is 7.51 km.
Explanation:
The information given states that,
The geese initially move 4.0 km directly west, then alter course to the north at a 40° angle, covering an additional 4.0 km.
Based on the diagram,
(a). To determine the distance
We will apply the distance formula
Insert the values into the equation
The resultant distance is 7.06 km westward.
(b). We will find the total displacement's magnitude
Using the displacement formula
Insert the values into the equation
The total displacement magnitude is 7.51 km.
In conclusion, (a). The traveled distance is 7.06 km towards the west.
(b). The magnitude of their total displacement is 7.51 km.
