Scientific Consensus is primarily a position, judgment, or a opinion of scientist in a particular area of there studies. So more or less like a opinion of the matter, its like saying, I don't agree with your study, and I think it should have been done another way.
First of all,
The electric field at the surface of the sphere is given by
E = kQ/r²
The field strength at which breakdown occurs in the air is <span>3.0 MV/m
</span>
So, E = 3.0 MV/m
<span>The sphere potential is defined as
V = kQ/r</span>
<span>If we divide E/V we get
E = V/r </span>
<span>r = V/E = 20000V / 3.10^6 V/m = 6.66 </span>10^-3 m = 6.66 mm
2. Charge
<span>V = kQ/r .............>>
</span>
Q = Vr/k = 20000V *( 6.66 10^-3 m)/ (9.10^9 N m2/C2) = 1.481 10^-8 C
Answer : The kinetic energy depends directly on the mass of a particle.
Explanation :
We know that the kinetic energy of any particle is given by :
Where,
m is the mass of an object.
v is the velocity with which it is moving
Kinetic energy is due to the motion of the particle.
So, the kinetic energy of a particle is directly proportional to its mass.
Hence, the conclusion of the question is if the mass of a particle is increases then its kinetic energy also increase.
Explanation:
<h2>Answer:-</h2>
The Object was at rest. So, Initial Velocity is Zero.
- [Initial Velocity]u = 0
- [Final Velocity]v = 20 m/s
- [Time]t = 2 seconds
- Mass = 4kg
- Force = ?
We know that:-
Applying it, we get:-
Hope it helps :)
Answer: Frequency is the rate of vibration and oscillation measured over a specific period of time (usually one second). In layman's terms, it's simply a repeating sequence.
