Answer:
Explanation:
Hi! It would be A. Plane mirrors produce only virtual images,and concave mirrors produce real and virtual images.
Plane mirrors construct only virtual images, and concave mirrors make real and virtual images. Thus, this statement best corresponds concave and plane mirrors.
What are virtual images?A virtual image exists represented as the opposite of a real image, thus an image that cannot be obtained on a screen stands produced as a virtual image. The motivation for this exists in the fact that the beams of light that form a virtual image never connect therefore a virtual picture can never be projected onto a screen. Examples: Image formed in a plane mirror, an image constructed on the front and back surfaces of a spoon, etc.
Therefore, the (A) option exists as the accurate answer.

Conclusion When there is a constant unbalanced force applied in the same direction as the motion, speed will ___________________ and acceleration will _____________________________. When there is an increasing unbalanced force applied in the same direction as the motion, speed will ___________________ and acceleration will ________________________. When there is a constant unbalanced force applied in the opposite direction as the motion, speed will ___________________ and acceleration will ________________________. When there is an increasing unbalanced force applied in the opposite direction as the motion, speed will ___________________ and acceleration will ________________________.
Explanation:
When there is a constant unbalanced force applied in the same direction as the motion, speed will increase and acceleration will remain constant. When there is an increasing unbalanced force applied in the same direction as the motion, speed will increase and acceleration will increase.
According to newton's 2nd law
F = ma
F ∝ a
meaning when F increases , a increases and vice versa

How can you drop two eggs the fewest amount of times, without them breaking?
Answer:
Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that's it for that egg.
For a given force as time ___
the impulse related to that force increases. *
A. increases
B. decreases
Answer:
Increases
Explanation:
For a given force, as the time increases, the impulse related to that force increases also.
Impulse and time are directly related to one another. Impulse is mathematically given as:
I = F t
I is the impulse
F is the force
t is the time taken
So, as both force and time increases, the value of the impulse must increase.

Two carts connected by a 0.25 m spring hit a wall, compressing the spring to 0.1 m. The spring constant k is 100 N m . What is the elastic potential energy stored from the spring's compression?
Given that,
Initial position of the spring, x₁ = 0.25 m
Final position of the spring, x₂ = 0.1 m
The spring constant of the spring, k = 100 N/m
To find,
The elastic potential energy stored from the spring's compression.
Solution,
The work done in moving a spring from on position to another is stored in the form of elastic potential energy. It can be given as follows :
[tex]E=\dfrac{1}{2}k(x_2^2-x_1^2)\\\\=\dfrac{1}{2}\times 100\times (0.1^2-0.25^2)\\\\=2.62\ J[/tex]
So, the required energy is 2.62 J.
Answer:
1.125 J
