Answer:
correct option is d) 7.0 x 10^-7 N
Explanation:
given data
distance = 175 picometers = 1.75 × m
to find out
electrical force
solution
we know atomic no of uranium is 92
and charge on electron is = 1.6 × C
and electrical force is express as
electrical force = .............1
put here value we get
electrical force =
electrical force = 6.921 × N
so correct option is d) 7.0 x 10^-7 N
Answer: a) It will take more time to return to the point from which it was released
Explanation: To determine how long it takes for the ball to return to the point of release and considering it is a free fall system, we can use the given formula:
, where:
d is the distance the ball go through;
v₀ is the initial velocity, which is this case is 0 because he releases the ball;
a is acceleration due to gravity;
t is the time necessary for the fall;
Suppose <em>h</em> is the height from where the ball was dropped.
On Earth:
h=0.t +
h = 5t²
=
On the other planet:
h = 0.t +
h = 15.t²
=
Comparing the 2 planets:
= or
Comparing the two planets, on the massive planet, it will take more time to fall the height than on Earth. In consequence, it will take more time to return to the initial point, when it was released.
Hello,
The answer is option A "<span>to create a more perfect Union".
Reason:
The constitution was created in order to form a better Union. Its not option B because the constitution is the very first step to forming the better country slavery wasn't abolished then Its also not option C because we broke free of Britain using "taxation without representation" which helps the colonists break free from Britain. Its also not option D because the country was already before women gained there rights.
If you need anymore help feel free to ask me!
Hope this helps!

So we want to know what will happen to the needle of a compass that is held upright and pointing left in front of the solenoid if the current in the solenoid is reversed. If the current is reversed in the solenoid then the direction of the magnetic field of the solenoid is also reversed. So the needle that was pointing left will now point right after the direction of the current is changed.
