Betelgeuse is how many times larger than the sun

Physics
1 answer:
Aleksandr-060686 [28]4 years ago
3 0
Betelgeuse is one of the largest known stars and is probably at least the size of the orbits of Mars or Jupiter around the sun. That's a diameter about 700 times the size of the Sun or 600 million miles. For a star it has a rather low surface temperature (6000 F compared to the Sun's 10,000 F).

Blown balloon kept outside on a sunny day bursts what will happen to the ballon​
Advocard [28]

When the balloon is kept in the sun, due to Sun's heat, the kinetic energy of gaseous particles inside the balloons also gets increased and the balloon expands. This will increase the pressure on the walls of the balloon. It continues to expand and comes to a stage when the baloon bursts.

A rotating wheel requires 2.90-s to rotate through 37.0 revolutions. Its angular speed at the end of the 2.90-s interval is 97.2
goldenfox [79]

Answer:

Angular acceleration, \alpha =20.32\ rad/s^2

Explanation:

It is given that,

Displacement of the rotating wheel, \theta=37\ rev=232.47\ radian

Time taken, t = 2.9 s

Initial speed of the wheel, \omega_i=0

Final speed of the wheel, \omega_f=97.2\ rad/s

Let \alpha is the angular acceleration of the wheel. Using the third equation of kinematics to find it as :

\alpha=\dfrac{\omega_f^2-\omega_i^2}{2\theta}

\alpha=\dfrac{(97.2)^2}{2\times 232.47}

\alpha =20.32\ rad/s^2

So, the angular acceleration of the wheel is 20.32\ rad/s^2. Hence, this is the required solution.

Two ice skaters suddenly push off against one another starting from a stationary position. The 50 kg skater acquires a speed of
Liono4ka [1.6K]

Answer:

V_{22}=0.25m/s

Explanation:

From the question we are told that:

Mass 1 M_1=50kg

Speed 1 V_1=0.3m/s

Mass 2 M_2=60kg

Generally the equation for momentum is mathematically given by

 M_1V_{11}+m_2V_{21}=M_1V_{12}+m_2V_{22}

Where

 v_{11}=v_{21}=0

Therefore

 M_1V_12-M_2V_22

 V_{22}=\frac{m_1v22}{m_2}

 V_{22}=\frac{m_1V_22}{m2}

 V_{22}=\frac{50*0.3}{60}

 V_{22}=0.25m/s
