Answer:

Angular diameter : degrees or radians

Explanation:

Angular diameter is an angular measurement of the objects. It is an angle subtended by the two points of an object from the observer's eye view. Its unit is measured in degrees or radians.

It is a geometrical technique used to measure the size of an object which is not directly measurable. For example, to measure the diameter of a planet.

In a collision, a 25.0 kg mass moving at 3.0 m/s transfers all of its momentum to a 5.0 kg mass.

nadezda [96]

Answer:

Explanation:

The momentum of the 25 kg mass is

$p=mv$

$p=25kg*3m/s= 75kg*m/s$

If this whole momentum of the object is transferred to the 5.0 kg object then according to the law of conservation of momentum, the momentum of the 25.0 kg object must be transferred to the 5.0 kg object:

$75kg*m/s = 5.0kg*v$

$v=\dfrac{75}{5}$

$\boxed{v=15m/s}$

How does the carbon rod of a cell beomes a positive<br>terminal?

ivann1987 [24]

Answer:

In the middle of a dry cell, is a rod made of carbon. Around the carbon rod is a chemical paste. At the same time, the carbon rod becomes positively charged. When this happens, electrical current flows out of the cell when a conductor is attached between the cell's positive and negative terminals.
