Answer:
si la. carga es positiva experimenta una fuerza en el sentido del campo
en cambio si la carga es negativa,experimenta una fuerza en sentido contrario al campo
Answer:
9.81 m/s²
Explanation:
It is given that the upward speed of the object is 8.9 m/s.
An object is released.
Now, we know that if the object is released then it will move under the control of gravity which means that the initial velocity of the rocket will not affect the acceleration of the object.
Hence, the downward acceleration of the object will be equal to g i.e. 9.81 m/s².
Answer:
Explanation:
Given
Three charges of magnitude q is placed at three corners and fourth charge is placed at last corner with -q charge
Force due to the charge placed at diagonally opposite end on -q charge
where Distance between the two charges
negative sign indicates that it is an attraction force
Now remaining two charges will apply the same amount of force as they are equally spaced from -q charge
The magnitude of force by both the charge is same but at an angle of
thus combination of two forces at 2 and 3 will be
Now it will add with force due to 1 charge
Thus net force will be
-- "Length of time" is described in units of time.
-- 'Light years' and 'light year kilometers' are both units of length or distance,
so those are not it.
-- "Decades" is a unit of time, but much too short.
Examples: Judaism has existed for more than 300 decades, the USA
has existed for more than 20 decades, and I have existed for more than
7 decades.
The expansion of the universe could be described in units of decades
if you really wanted to, but that would result in a ridiculous number.
It would be about as inconvenient as discussing the expansion of the
universe in units of seconds or minutes.
-- For just about the same reason, "millions of years" is also a too-small unit.
-- When you're talking about stages in the existence of the universe,
the only unit from this list that makes sense is billions of years, or even
multiple billions.
