I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?

The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.

What is the angular diameter of Earth as seen from the moon?
Since Earth has about 4 times the diameter of the Moon, the angular diameter of Earth, as seen from the Moon, is about 4 times larger than the angular diameter of the Moon, as seen from Earth. Since the Moon's angular diameter as seen from here is about half a degree, that would make Earth's angular diameter about 2 degrees.If you wish, you can look up more exact figures and do more precise calculations, but it is hardly worth the trouble, since there is some variation in the distance from Earth to Moon anyway.
What is the angular size of the Sun and the Moon in order for solar eclipses to occur?
* For a solar eclipse, there is no specific requirement about the angular sizes.* For a TOTAL solar eclipse, the angular diameter of the Moon must be larger than that of the Sun.
10 What is the angular diameter of the sun or moon in the sky?
Roughly 1/2 degree
Is the angular diameter of the moon is smaller than that of the sun?
The Sun is about 416 times larger than the Moon. You could place about 71,991,296 Moons inside the Sun. The Sun has a diameter of 1.392×106 km The Moon has a diameter of 3,474.2 km
Why do neutron stars tend to have high angular velocities?
That's because of conservation of angular momentum - and the fact that neutron stars are very small. If a star the size of our Sun rotates (for example) once a month, once it shrinks to a diameter of 20-30 km., it will have to rotate several times per second in order to conserve angular momentum.
What is an angular speed of a rotating body?
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
A motorcycle generates 500W of power The torque is 50.0 N m What is the angular velocity?
General formula used to calculate torque from power is torque=power*9.55/rpm so,using your data,50=500*9.55/N(rpm) i.e.,N(rpm)=95.5rpm. Angular Velocity=3.147*d*N/60 Unless the diameter is unknown its not possible to calculate the angular velocity.Once diameter is known it can substituted in the above mentioned formula.
Why is angular displacement a vector quantity?
Angular displacement is a vector quantity because it has both magnitude and direction. The direction of angular displacement is determined by the axis of rotation and follows the right-hand rule, while the magnitude is given by the angle of rotation. As a vector, angular displacement can be added, subtracted, and resolved into components, making it useful in calculations that involve rotational motion.

Why does a star look smaller than another star but is bigger than the other star?
Normally you would observe the star's brightness, not its apparent diameter.The star's apparent brightness ("apparent magnitude") depends on its real brightness ("absolute magnitude"), and on the distance. Similarly, the star's apparent angular diameter (which is VERY hard to measure) would depend on its actual diameter, and on the distance.
Use the small-angle formula to find the angular diameter of mars when it is closest to Earth how does that compare with the maximum diameter of Jupiter?

What is the angular diameter of the moon just above the horizon?
163.36
Do the sun and moon have the same angular diameter?
It is true that as seen fro the earth the sun and the moon have roughly the same angular diameter. It is for that reason that total solar eclipses are so spectacular.
What is the meaning of angular frequency for a body undergoing simple harmonic motion?
Angular frequency differs from frequency by factor '2Pie'. It has the dimension of reciprocal time(same as angular speed). Its unit is radian/sec. Or you can simply say that angular frequency is the magnitude of angular velocity(a vector quantity).
What is the angular diameter of both the sun and moon?
1/2 a degree
A marble has a diameter of 2 cm At what distance would the marble have an angular diameter of 1 arc second?
6.5cm
Does friction have anything to do with numbers?
Yes, friction is a force it possesses magnitude and direction. It's magnitude and direction are measured in in Newtons and radians (or other angular measurement) which are written in numbers.No friction is a phenomenon; numbers a human idea. But numbers can be used by humans to express and calculate many things which concern friction.
