When θ= 0 ̊, the assembly is held at rest, and the torsional spring is untwisted. if the assembly is released and falls downward

Final temperature to determine: Given the following details, the calculations proceed as follows: Mass of the silver ring is m = 4 g, initial temperature is presented, and the heat released is Q = -18 J (indicating heat loss). The specific heat of silver is considered next to find the final temperature.

Answer:

0.0031 m

Explanation:

y = Length of pixel = 281 μm

L = Distance to screen = 1.3 m

= Wavelength = 550 nm

d = Pupil diameter

= Angle

We have the expression

We have the expression

The pupil diameter calculates to 0.0031 m

Response:

The acceleration of car 2 is four times that of car 1.

Rationale:

Centripetal acceleration occurs when an object travels in a circular route. It can be expressed as:

In this scenario, two race cars are moving at consistent speeds around a circular course. Both automobiles are located at an equal distance from the center, but car 2 is operating at twice the speed of car 1.

Thus,

1 and 2 represent the first and second cars, respectively.

Consequently,

Therefore, car 2's acceleration is four times that of car 1.

Answer:

10m/s

Explanation:

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
