Answer:
The magnitude of the force on an electron is 0.069 N.
Explanation:
Given that,
Distance between 1.70 A from the plutonium nucleus, 
The number of electron in iron nucleus is +26e.
To find,
The magnitude of the force between an iron nucleus.
Solution,
Total charge in the plutonium nucleus is,
. The electric force between charges is given by :


F = 0.069 N
So, the magnitude of the force on an electron is 0.069 N. Hence, this is the required solution.
Answer:
a) 
b)
degrees and on this case to the South of the East.
c)
d) 
So it would be 250 to the South
Explanation:
Part a
For this case the figure attached shows the illustration for the problem.
We know that
represent the velocity of the river to the south.
We have the velocity of the motorboard relative to the water and on this case is 
And we want to find the velocity of the motord board relative to the Earth 
And we can find this velocity from the Pythagorean Theorem.

Part b
We can find the direction with the following formula:
degrees and on this case to the South of the East.
Part c
For this case we can use the following definition

The distance would be D = w = 600 m and the velocity V = 4.8m/s and if we solve for t we got:

Part d
For this case we can use the same definition but now using the y compnent we have:

And replacing we got:

So it would be 250 to the South
Speaking that the trash can absorb the momentum. It only should go 5
Answer:
Weight is a consequence of the universal law of gravitation
Explanation:
Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Explanation:
Ubuntu is somewhat a South African concept that involves charity, sympathy, and mainly underlines the concept of universal brotherhood. Hence this concept can help fight social challenges such as racism, crime, violence and many more. It can contribute to maintaining peace and harmony in the country at large
