The mirror formula for curved mirrors is:
\frac{1}{f}= \frac{1}{d_o}+ \frac{1}{d_i}
where
f is the focal length of the mirror
d_o is the distance of the object from the mirror
d_i is the distance of the image from the mirror

The sign convention that should be used in order to find the correct values is the following:
- f: positive if the mirror is concave, negative if the mirror is convex
- d_i: positive if the image is real (located on the same side of the object), negative if it is virtual (located on the opposite side of the mirror)

A rectangular field is of length 42 cm and breadth 25 m. Find the area of the field in SI unit. EXPLAIN STEP BY STEP​
lorasvet [3.4K]

Answer:

the area of the rectangular field is 10.5 m²

Explanation:

Given;

length of the rectangular field, L = 42 cm = 0.42 m

breadth of the rectangular field, b = 25 m

The area of the rectangular field is calculated as follows;

Area = Length x breadth

Area = 0.42 m x 25 m

Area = 10.5 m²

Therefore, the area of the rectangular field is 10.5 m²

. Which Of The Following Will Produce Diffuse Reflection Of Light?
Ganezh [65]

Answer:

A. Plane mirror and piece of paper

Explanation:

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. An ideal diffuse reflecting surface is said to exhibit Lambertian reflection, meaning that there is equal luminance when viewed from all directions lying in the half-space adjacent to the surface.

PtichkaEL [24]

Answer:

vf = 14.2176 m/s

Explanation:

Given

m = 4 Kg

viy = 7.00 ĵ m/s

Fx = 11.0 î N

t = 4.5 s

vf = ?

Using the Impulse - Momentum Theorem, we have

F*Δt = m*Δv    ⇒  F*Δt = m*(vf - vi)

⇒    vf = (F*Δt + m*vi) / m

⇒    vf = (F*Δt + m*vi) / m

For <em>x-component</em>

⇒    vfx = (Fx*Δt + m*vix) / m = (11 N*4.5 s + 4 Kg*0 m/s) / (4 Kg)

⇒    vfx = 12.375 î m/s

For <em>y-component</em>

⇒    vfy = (Fy*Δt + m*viy) / m = (0 N*4.5 s + 4 Kg*7 m/s) / (4 Kg)

⇒    vfy = 7 ĵ m/s

Finally:

vf = √(vfx² + vfy²)

⇒   vf = √((12.375 m/s)² + (7 m/s)²)

⇒   vf = 14.2176 m/s
