A parallel plate capacitor fully charged to voltage V is connected to the battery (the voltage on the plates remains fixed). If
Papessa [141]

Charge will decreases.

A parallel plate capacitor when it is fully charged to voltage V is given as:

                    C = Q/V

The capacitance of parallel plate capacitor with two plates of Area A separated by distance d and no dielectric material between plates is

                    C = ε₀ A /d

since from above equation it shows C is proportional to Q and also C is inversely proportional to distance d.

So, ATQ when d increases C will decrease which in result decreases charge on the capacitor.

Thus,  Charge will decrease.

D=44.13, Horizontal velocity is unimportant. The time it takes the cannon ball to fall to the ground is the key to determining the height of the cliff. where  that cannon is present.

The speed of any projectile travelling along a Horizontal velocity is known as the horizontal velocity. When a particle or object is launched into the air at an angle other than 90 degrees, it moves along the trajectory path and changes the shape of the curve to a parabolic one.

the speed at which velocity changes over time. Due to its magnitude and direction, acceleration is a vector quantity. The first derivative of velocity with respect to time or the second derivative of position with respect to time are further examples. This is called acceleration.

Distance to the ground is d = 1/2gt^2,

where g is the acceleration rate of gravity (9.80665 m/s^2)

and t = 3 secs.

d = .5×9.80665×9 = 44.13 m.

True/False
Alborosie

Answer:

True

Explanation:

Scientists and professionals in health sciences are invited to participate in congresses, conferences and events. Communications to conferences can be of different types, but it is always necessary to draw a table with the contents that you want to present.

Due to the rise and importance of conferences in recent years, scientists and scientific societies that provoke conferences have gained greater knowledge of the importance of defining their publications, so that the problems related to these issues are becoming smaller .

It is important to know how to write the communication and if the conference proceedings or reports will be considered as primary publication, then it is recommended to prepare the manuscript in the same style as the journal articles. For this it is recommended to use the same method.
