True

Explanation: Since the cornea is a curved surface, it acts like a convex lens and begins to focus the light rays. The light then passes through the pupil and hits the lens of the eye. The lens, also convex, further focuses the light so that it will hit the retina at the back of the eyeball.

A 26 cm object is 18 cm in front of a plane mirror. A ray of light strikes the object and is reflected off the mirror at a 42-de

natita [175]

The angle of reflection is the angle between the reflected ray and the normal.
In this case the angle of reflection is 42 degrees

Characteristics of images formed in a plane mirror include
The image is upright
The image is virtual
the image is the same size as the object
The image is at the same distance from the mirror as the object
The image is formed behind the mirror

A plane mirror forms an image which is the same size as the object
Therefore since the object is 26 cm long , the image would still be 26 cm.

A 1.20 × 104 kg railroad car moving at 7.70 m/s to the north collides with and sticks to another railroad car of the same mass t

saul85 [17]

Answer: 4.77m/s

Explanation:

According to the law of conservation of momentum which states that the sum total of momentum of bodies before collision is equal to the sum of their momentum after collision. Note that the two bodies will move at a common velocity after colliding.

Let m1 and m2 be the mass of the first and second railroad cars

u1 and u2 be the velocities of the railroad cars

v be the common velocity

Using the formula

m1u1 + m2u2 = (m1 +m2)

m1 = 1.20×10⁴kg

m2 = 1.20×10⁴kg (body of same mass)

u1 = 7.70m/s

u2 = 1.84m/s

v = ?

(1.20×10⁴×7.7) + (1.20×10⁴×1.84) = (1.20×10⁴ + 1.20× 10⁴)v

9.24×10⁴ + 2.21×10⁴ = 2.4×10⁴v
