If two tiny identical spheres attract each other with a force of 2.00 nn when they are 20.0 cm apart, what is the mass of each s
attashe74 [19]

The mass of each sphere is m=1.7kg

<h3>What is the mass?</h3>

The amount of matter in a particle or object is represented by the dimensionless quantity mass (symbolized m). The kilogram is the chosen unit of mass according to the International System (SI) (kg).

<h3>According to Given Information:</h3>

We'll apply the formula.

Now take note that the value we must discover is m1 = m2 = m. When m is solved for,

m=1.7kg is obtained using the formulas Fg = 2.0 109 N and G = 6.673 1011 N m2/kg2.

<h3>What is the force?</h3>

A force refers to the push or pull that such an object feels when it comes into contact with another object. A force is applied to each object when two things come into contact. The interaction between the two items stops when the force is no longer looks by either.

Newton's second
Andru [333]

Explanation:

The second law states that the greater the mass of an object, the more force it will take to accelerate the object. There is even an equation that says Force = mass x acceleration or F=ma. This also means that the harder you kick a ball the farther it will go.

An AC source is rated 220 V, 50 Hz. The average voltage is calculated in a time interval of o.01 s. It (A) must be zero (C) is n
dimaraw [331]

ANSWER AND EXPLANATION:

--------------------------------------------------------------------------------------------------------------

                                                 INFORMATION

--------------------------------------------------------------------------------------------------------------

Frequency - 50Hz. Which means that the time period of the wave if 1/50 = 0.02 sec. Here we are going to check the average voltage for the time interval of 0.01sec. If the interval lies between π/2 to 3π/2. the average voltage will be zero. In all the other cases it will not be zero

--------------------------------------------------------------------------------------------------------------

                                                    ANSWER

--------------------------------------------------------------------------------------------------------------

                              So, the answer will be <u><em>may be zero. </em></u>
