Answer:

F = 8.45 * 10^-8 N

Explanation:

The gravitational force is calculated using

F = GMm/r²

Where

G represent gravitational constant = 6.67 * 10^(-11)

M = Mass of the boy = 78kg

m = Mass of the girl = 65kg

r = Distance between them = 2m

Substitute these values in the formula, we have:

F = (6.67 * 10^(-11) * 78 * 65)/2²

F = (6.67 * 78 * 65 * 10^(-11))/4

F = (33816.9 * 10^(-11))/(4)

[Divide by the denominator]

F = 8454.225 *10^(-11)

[Expand]

F = 8.454225 * 10³ * 10^(-11)

F = 8.454225 * 10^(3-11)

F = 8.454225 * 10^-8

[Approximate]

F = 8.45 * 10^-8 N

Hence, the force of attraction between them is 8.45 * 10^-8 N

o-na [289]

The continuous neutral-current rating be for an autotransformer used to create a three-phase, it must be sufficient to handle the maximum possible neutral unbalanced load. 450.5.

<h3 /><h3>What is meant by autotransformer?</h3>

A grounding autotransformer is used to create a three-phase, 4-wire distribution system from a three-phase, 3-wire ungrounded system.

A three-phase autotransformer is a special type in which common winding is shared by the high voltage and low voltage. Three-phase AC is supplied at primary and output is collected at secondary. Three phase autotransformer is used for such applications where a small voltage is used in the distribution system.

Autotransformers are frequently used in power applications to interconnect systems operating at different voltage classes, for example, 132 kV to 66 kV for transmission. Another application in industry is to adapt machinery built (for example) for 480 V supplies to operate on a 600 V supply.

Kitty [74]

Answer:

<u>Social</u> neuroscience seeks to identify the neural basis of social behavior and looks at how we can illuminate our understanding of groups, interpersonal relations, and emotions by understanding their cognitive underpinnings.

Explanation:

Social neuroscience can be defined as the interdisciplinary study of multilevel neurobiological processes (nervous, endocrine, immune) that allow us to interact with the social world, of how neurobiological events affect psychosocial processes and how these, in turn, have effects at the biological level, that is, it addresses fundamental questions about the mind and its dynamic interactions with the biological systems of the brain and the social world in which it resides. This field studies the relationship between neural and social processes, including the intermediate components of information processing and operations at the levels of neural and computational analysis.
