Answer:
The <em>correct</em> statements are:
- <em>A. The electric field is nonuniform.</em>
- <em>D. Charge Q is positive.</em>
- <em>E. If charge A moves toward charge Q, it must be a negative charge</em>
Explanation:
The answer choices are:
- A. The electric field is nonuniform.
- B. The electric field is uniform.
- E. If charge A moves toward charge Q, it must be a negative charge.
- F. If charge A moves toward charge Q, it must be a positive charge.
<h2>Solution</h2>
The <em>electric field</em> is the electrostatic force per unit of charge,
around around a charge, where another charge would experience the electrostatic force.
The electric field lines are shown in a diagram with arrows ditributed radially away from a positive charge and radially toward a negative charge.
Since the arrows are away from Q, Q is a positive charge: <em>statement D.</em>
Since the size of the arrows decreases as you move away from Q the stregth of the field is not uniform: <em>statement A.</em>
Since the charge Q is positive, a negative charge would be attracted toward it: <em>statement E.</em>

Answer:
more than 51.45 N
__________________________________________________________
<u>We are given:</u>
Mass of the television = 15 kg
Coefficient of Static friction = 0.35
<u>Minimum force required to move the television:</u>
<u>Normal Force:</u>
We know that the normal force is equal and opposite to the Weight of the television
Weight of the television = Mg
[<em>where m is the mass and g is the acceleration due to gravity</em>]
Weight = 15 * 9.8
Weight = 147 N
<u>Force of Friction:</u>
We are given the coefficient of Friction = 0.35
We know that coefficient of Friction = Force of friction / Normal Force
<em>replacing the variables</em>
0.35 = Force of Friction / 147
Force of Friction = 147 * 0.35 [<em>multiplying both sides by 147</em>]
Force of Friction = 51.45 N
Since a force of 51.45 N is will be applied opposite to the direction of application of Force, the television will only move when we apply more force than 51.45 N
The kind of wave it is Longitudinal
Answer:
d = 105 m
Explanation:
Speed of a car, v = 21 m/s
We need to find the distance traveled by the dar during those 5 s before it stops. Let the distance is d. It can be calculated as :
d = v × t
d = 21 m/s × 5 s
d = 105 m
So, it will cover 105 m before it stops.
