Answer:
0.75 NC⁻¹
Explanation:
Electric field intensity ( or strength of the electric field ) is the force per a 1 C charge,
So, Force (F) = Electric field intensity(E) × Charge (q)
F = E×q ⇒ q = F/E
= 4.5×10⁻⁴/6×10⁻⁴ = 0.75 NC⁻¹
According to cool om's law electric fields are generated due to charges. When charges are same there is a repulsive force acted on both charges. When charges are opposite there is a attraction force acted on both charges.
According to cool om's law,
F =G×q1×q2 / r²
F = force exerted of two charges
q1 , q2 = charges
r = distance between two charges
And also Electric field intensity is a vector which has a magnitude and direction both. Direction is depending on a charge and the sign of the charge
The direction of the centripetal acceleration is towards Saturn
Explanation:
When an object moves in a circular motion, there must be a force that "pulls" the object towards the centre of the circle, keeping it in a circular motion. This force is called centripetal force.
As a consequence, due to the relationship between force and acceleration (Newton's second law), there is also an acceleration that points towards the centre: this acceleration is called centripetal acceleration.
The magnitude of the centripetal acceleration is given by:
where
m is the mass of the object
v is its speed
r is the radius of the circle
Therefore in this situation, the centripetal acceleration points towards the centre of the circle: therefore, towards Saturn, which occupies the centre of the circular trajectory.

It would be B because it makes science to the topic
Answer:
Is fire matter? Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter.
