Un cuerpo gira con movimiento circular uniforme un ángulo total de 1080° en 20

LekaFEV [45]

Velocidad angular = (angulo total) / (tiempo total)

Velocidad angular = (1080 grados) / (20 segundos)

Velocidad angular = (1080/20) g/s

Velocidad angular = 54 g/s

Pero 180 grados = π radianes

V.A. = (54 g/s) x (π rad / 180 g)

V.A. = (54π gr-rad / 180 seg-gr)

<em>V.A. = 0.3π rad/seg</em>

V.A. = aproximadamente 0.942 rad/seg

Object A weighs 750 N on earth. Object B weighs 750 N on Jupiter.

Katarina [22]

The object A has the greater mass compared to object B.

<u>Explanation: </u>

The weight of any object on any planet is the measurement of gravity’s influence acting on the mass of the object. So for Earth, the acceleration will be acting on the object A’s mass (m) in Earth leading to the weight of the object A as 750 N.

While the acceleration of Jupiter will be acting on the object B’s mass kept in Jupiter to attain the weight of 750 N. So, the mass of both the objects at their respective planet will vary depending on the acceleration of each planet. We can check this as below:

$\text { object A's weight }=\text { m of object A } \times \text { Acceleration of Earth}$

So,

$750 \mathrm{N}=\text { m of object } A \times 9.8 \mathrm{m} / \mathrm{s}^{2}$

Thus,

$\text { m of object } A=\frac{750}{9.8}=76.5 \mathrm{kg}$

Similarly for object B,

$\text { Weight of object } B=m \text { of object } B \times \text { Acceleration due to gravity of Jupiter }$

$750 = m \text { of object } B \times 24.79 \mathrm{m} / \mathrm{s}^{2}$

Thus,

$\text { m of the object } B=\frac{750}{24.79}=30.25 \mathrm{kg}$

Thus, the mass of object A is greater than the mass of object B.

What is the length of an aluminum rod at 65Â°C if its length at 15Â°C is 1.2 meters? A. 0.00180 meter B. 1.201386 meters C. 1.2

Deffense [45]

Answer:

Option B is the correct answer.

Explanation:

Thermal expansion

$\Delta L=L\alpha \Delta T$

L = 1.2 meter

ΔT = 65 - 15 = 50°C

Thermal Expansion Coefficient for aluminum, α = 24 x 10⁻⁶/°C

We have change in length

$\Delta L=L\alpha \Delta T=1.2\times 24\times 10^{-6}\times 50=1.44\times 10^{-3}m$

New length = 1.2 + 1.44 x 10⁻³ = 1.2014 m

Option B is the correct answer.
