Two parallel conducting plates are separated by 9.2 cm, and one of them is taken to be at a potential of zero volts.What is the
True [87]

Answer:

E=54V/cm

\Delta V=496.8V between the plates.

Explanation:

The equation for change of voltage between two points separated a distance d inside parallel conducting plates (<em>which have between them constant electric field</em>) is:

\Delta V=Ed

So to calculate our electric field strength we use the fact that the potential 8.8 cm from the zero volt plate is 475 V:

E=\frac{\Delta V}{d}=\frac{475 V}{8.8cm}=54V/cm

And we use the fact that the plates are 9.2cm apart to calculate the voltage between them:

\Delta V=Ed=(54V/cm)(9.2cm)=496.8V

A projectile is launched from ground level at an angle of 50.0 degrees above the horizontal with a speed of 30.0 m/s. If the pro
Allushta [10]

Answer:

4.69 s

Explanation:

u = Initial velocity = 30 m/s

\theta = Angle of launch = 50^{\circ}

g = Acceleration due to gravity = 9.81\ \text{m/s}^2

Time taken by the projectile to land is given by

t=\dfrac{2u\sin\theta}{g}\\\Rightarrow t=\dfrac{2\times 30\times \sin50^{\circ}}{9.81}\\\Rightarrow t=4.69\ \text{s}

The time the projectile is in the air before it contacts the ground again is 4.69 s.
