The convex spherical mirror is the diverging mirror. The image distance is 20.4 cm. The magnification is 0.417. The image is virtual and upright.

Magnification is the ratio of image distance to the object distance.

Object distance is 49 cm and the focal length of convex mirror is 35 cm, then image distance is calculated by the lens maker formula.

1/f = 1/v +1/u

1/-35 = 1`/v +1/49

v= -20.4 cm

Thus, the image distance is 20.4 cm.

The magnification is given by

m = v/u

m = -20.4 / 49

m = 0.417

Thus, the magnification is 0.417.

The image formed is by virtual meeting of light rays and above the principle axis. Thus the image is virtual and upright.

Sound waves go along a corridor, past an open doorway. All the waves will have the most difficulty diffracting through the doorway. Option D is correct.

Diffraction refers to a variety of events that occur when a wave collides with a barrier or an opening.

Diffraction is described as the bending of waves around the corners of an obstruction or through an aperture into the region of the obstacle's geometrical aperture's shadow.

The one with the longer wavelength will readily diffract. As a result, the one with a wavelength of 100 m can diffract readily.

Sound waves have a wavelength of 16.6 ×10⁻³ to 16.6 m in comparison to other waves. Which are audible to them, allowing them to diffract readily.

Sound waves go along a corridor, past an open doorway. All the waves will have the most difficulty diffracting through the doorway.

Answer:

2600 cubic centimeters

Explanation:

Volume of the edible fruit is equal to :

⇒ Volume (fruit) - Volume (seed)

⇒ 4/3π(3r)³ - 4/3πr³

⇒ 27 x 4/3πr³ - 4/3πr³

⇒ 100 (27 - 1)

⇒ 2600 cubic centimeters

The volume of the edible fruit, rounded to the nearest cubic centimeter, is approximately 1188 cubic centimeters.

Given that the volume of the seed is 100 cubic centimeters, we can use the formula for the volume of a sphere to relate the radius and volume:

V(seed) = (4/3)πr³

100 = (4/3)πr³

Next, we can determine the radius of the fruit by multiplying the radius of the seed by 3:

R(fruit) = 3r

V(fruit) = (4/3)π(R(fruit)³ - r³)

V(fruit) = (4/3)π((3r)³ - r³)

V(fruit) = (4/3)π(27r³ - r³)

V(fruit) = (4/3)π(26r)

Now, substitute the value of r from the first equation into the expression for V(fruit):

V(fruit) = (4/3)π(26 × ∛(100/(4/3)π))

V(fruit) = 1188 cubic centimeters

Therefore, the volume of the edible fruit, rounded to the nearest cubic centimeter, is approximately 1188 cubic centimeters.
