Answer:

For a positive point charge, the lines radiate outward. While, for a negative point charge, the lines converge inward.

Explanation:

The electric field produced by a single point charge has a radial shape and follows an inverse square law. The magnitude is given by

E=k\frac{q}{r^2}

where

k is the Coulomb's constant

q is the magnitude of the charge

r is the distance from the charge

The direction of the field depends on the sign of the charge. In particular, we have:

  • For a positive charge, the direction of the field is out of the charge
  • FOr a negative charge, the direction of the field is towards the charge

This is due to the fact that the direction of the field shows the direction of the force that a positive test charge would experience in this field. Therefore, since a positive test charge would feel a repulsive force in the field produced by a positive charge, then the direction of the field is outward; on the other hand, a positive test charge would feel an attractive force in the field produced by a positive charge, therefore the direction of the field is inward.

A motorcycle that is slowing down uniformly covers 2.0 successive km in 80 s and 120 s, respectively. Calculate (a) the accelera
8090 [49]

Answer:

acceleration = -0.042 m/s²

velocity at beginning =  14.167 m/s

velocity at  end = 5.7183 m/s

Explanation:

given data

distance d1 = 1 km

distance d2 = 2 km

time  t1 = 80 s

time t2 = 120 s + 80s = 200 s

to find out

acceleration and velocity at beginning and end

solution

we apply here law of motion that is

d = vt + 1/2×at²    

put value

1000 = v(80) + 1/2×a(80)²           ........................1

and

2000 = v(200) + 1/2×a(200)²      ........................2

so from equation 1 and 2 we get a and v

a = -0.042 m/s² and

v = 14.167 m/s

so by kinematic final velocity will be

V² = v² + 2ad

V² = (14.167)² + 2×(-0.042)×(2000)

V²  = 32.70

V = 5.7183 m/s

so

acceleration = -0.042 m/s²

velocity at beginning =  14.167 m/s

velocity at  end = 5.7183 m/s

Discuss the causes, characteristics, and major features of black holes. Explain why the concept of a black hole does or doesn't
tino4ka555 [31]

The concept of a black hole seem reasonable to me because of its valid and authentic evidences.

<h3>What are the causes, characteristics, and major features of black holes?</h3>

A black hole is a region in space where light is unable to escape due to strong gravitation force. The strong gravity is formed because matter has been pressed into a tiny space. This compression occurs at the end of a star's life. Some black holes are formed when a stars die.

So we can conclude that the concept of a black hole seem reasonable to me because of its valid and authentic evidences.
