Answer:
Neutrons
Explanation:
Neutrons are subatomic particles that are electrically neutral and possess no charge in them.
Answer:
Answer = 3.16m
Explanation:
The concept applied here is the relationship between intensity and sound level. the intensity I of a sound wave is the average rate per unit area at which energy is transferred.
I = P/A
I = intensity
A = Area
The intensity of a sound wave can also be expressed in terms of the decibel scale. DB is the abbreviation for decibel which is the unit of sound level this was named after Alexander Graham bell whose work on this aspect was recognized.
The step by step calculation and necessary derivations is a shown in the attachment.
The tralational equilibrium condition allows finding that the electric potential is V = 4.8 10¹¹ V
Given parameter
- The mass m = 1.5 g = 1.15 10-3 kg
- The charge on the sphere q = 8.9 10-16 C
- Plate spacing d = 5 cm = 5.00 10-2 m
To find
Newton's second law states that the force is proportional to the mass and the acceleration of the bodies, in the special case that the acceleration is zero, it establishes the condition for the equilibrium of the bodies
∑ F = 0
Where the bold indicate vector and F is the force
To use this equation we must fix a reference system with respect to which to carry out the decomposition and measurements of the forces; let's fix a system with the horizontal x axis and the vertical y axis, in the attachment I could see a free body diagram.
x- axis
Fe - Tₓ = 0
Fe = Tₓ
y-axis
- W = 0
W =
mg =
The electric force is
Fe = q E = q V / d
let's use trigonometry to decompose the stress
cos 30 = / T
sin 30 = Tₓ / T
= T cos 30
Tₓ = T sin 30
We substitute
q V / d = T sin 30
mg = T cos 30
It's solve the system of equations
= tan 30
V =
It's calculate
V =
V = 4.768 10¹¹ V
In conclusion, using the equilibrium condition, we could find that the electric potential is V = 4.8 10¹¹ V

Newton's laws allow to find the result for the movement of the basketballl:
-
On the vertical axis the ball is on the ground.
- On the horizontal axis the ball is accelerating in the direction of the pushing force.
Newton's laws establish the relationship between the forces on objects:
- The 1st law states that if the net force is zero the object is stationary or with constant speed.
- The 2nd law gives a relation of the force with the mass and the acceleration of the body.
- The 3rd. Law states that the force appears in pairs, one on each body with the same magnitude, but in the opposite direction.
Let's apply these principles to the ball's motion diagram.
The two vertical forces are in the opposite direction, one is due to the weight of the body and the other is the attraction of the earth to the support of the ball, they are of equal magnitude, not their action-reaction force and reluctant because it is applied to the same body
In conclusion we can say that the ball is on the ground.
The two horizontal forces are in the opposite direction, the thrust force is greater than the friction therefore using Newton's second law the ball must be accelerating in the direction of the thrust force.
In conclusion we can say that the ball is accelerating in the direction of the pushing force.
In conclusion using Newton's laws we can find the result for the motion of the basketball:
-
On the vertical axis the ball is on the ground.
- On the horizontal axis the ball is accelerating in the direction of the pushing force.
