- The length of its image =
Given,
length of object, 
We know, for flat refracting surface,
Image distance = object distance
So,
magnification is = 
length of the image,
Here, negative sign means inverted image.

Power = Net Force x velocity
Net force = driving force - force of resistance
Driving force = mass x acceleration
Acceleration = (final velocity - initial velocity) / time
Acceleration = (18 - 0) / 12 = 1.5 m/s²
Driving force = 1.5 x 10³ x 1.5
= 2250 N
Net force = 2250 - 400
= 1850
Power = 1850 x 18
= 3.33 x 10⁴ Watts
False, Compounds can contain more than 2 elements.
Answer:
1. Mass
2. Height
3. Gravitational Force Field
Explanation:
The three factors that decide how much gravitational potential energy a body has are: 1) The mass of the body itself, 2) The relative height at which the body is, because gravitational force varies with height i.e distance away from earth surface. 3) and finally the strength of the gravitational field the body is in.
The answer is to the question is strong and has a long range. The appropriate response is Strong, short range. The nuclear force is a compel that demonstrations between the protons and neutrons of particles. Neutrons and protons, both nucleons, are influenced by the atomic drive indistinguishably.
