large electroscope is made with "leaves" that are 78-cm-long wires with tiny 43 g spheres at the ends. When charged, nearly all

the charge resides on the spheres. If the wires each make a 26∘ angle with the vertical , what total charge Q must have been applied to the electroscope?

The difference in potential between the accelerating plates of a TV set is about 24 kV. The distance between these plates is 1.5
ryzh [129]

Answer:

So electric field between the plates will be equal to 1600\times 10^3KN/C

Explanation:

We have given potential difference between accelerating plates = 24 KV = 24000 volt

Distance between the plates d = 1.5 cm = 0.015 m

We know that potential difference is given by V = Ed, here E is electric field and d is distance between plates

So 24000=E\times 0.015

E = 1600000 N/C = 1600\times 10^3KN/C

So electric field between plates will be equal to 1600\times 10^3KN/C

What is Particle-antiparticle annihilation after watching the video minutephysics Antimatter Explained
LenKa [72]

Answer:

Particle-antiparticle annihilation is the result of a direct interaction between a particle and its corresponding anti particle, like a proton and an anti-proton or an electron and a positron. The result of such interaction is the production of two powerful gamma rays, each of whom has an energy roughly equal to E = mc^2, where m is the mass of the particle.

a vehicle starts from rsst and after 10 seconds its velocity is 20m/s find the acceleration and the distance travelled.(step by
Naily [24]

Answer:

<u>Acceleration is 2 m/s² </u>

<u>Distance</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u>0</u><u> </u><u>m</u>

Explanation:

From definition of acceleration, Acceleration is the rate of change in velocity.

• Simplifying the definition, or modifying it;

{ \boxed{ \rm{acceleration =  \frac{(final \: velocity - initial \: velocity)}{time} }}}

• Let's formulate symbols:

{ \boxed{ \rm{a =  \frac{v - u}{t} }}}

  • a is acceleration
  • v is final velocity, v = 20 m/s
  • u is initial velocity, u = 0 m/s [ at rest ]
  • t is time, t = 10 seconds

{ \rm{a =  \frac{20 - 0}{10}  =  \frac{20}{10} }} \\  \\{ \boxed{ \rm{ \: a = 2 \:  {ms}^{ - 2} }}}

Distance = ut + ½at²

Distance = (0 × 10) + (½ × 2 × 10²)

Distance = 0 + 10²

Distance = 100 meters
