(1) The image of an object placed further from the lens than the focal point will be upside down and smaller than the object.
(2) When light rays reflect, they bounce back.
(3) Images formed by a concave lens will look magnified.
(4) When light rays enter a different medium, they bend.
<h3>
1.0 Object placed further from the lens than the focal point</h3>
The image of an object placed further from the lens than the focal point will be diminished and inverted.
Thus, the correct answer will be "upside down and smaller than the object".
<h3>2.0 What is reflection of light?</h3>
The ability of light to bounce back when it strike a hard surface is known as refection.
<h3>3.0 Image formed by concave lens</h3>
A concave lens is diverging lens is usually virtual, erect and magnified.
<h3>4.0 Refraction of light</h3>
The change in speed of light when it travels from medium to another medium is known as refraction. Refraction is also, the ability of light to bend around obstacles.

Answer:
P=F/A where F is the weight of the water and A is the area on which it is resting. The weight of the water is mg. The mass of the water is dv where d is the density and v is the volume. Finally, the volume of the water in a vessel is equal to the area of the base of the vessel times the height of the vessel. (v=Ah)
Plugging everything in we get:
P = dAhg/A
So
P=dhg
So we have shown that liquid pressure is directly proportional to height of liquid in a vessel.
Explanation:
An adiabatic process is defined as a process in which transfer of heat is equal to zero. According to the first law of thermodynamics, any change in the internal energy is actually in the form of work done.
This means that change in internal energy will be as follows.
Change in internal energy = -work one by the gas
Therefore, we can conclude that true statements for an adiabatic process is as follows.
- During an adiabatic process, the internal energy of the system changes.
- During an adiabatic process, there is no heat transfer into or out of the system.

hlo dear
I am topper72 and I am brainly user
what's your problem pls post one by one question otherwise noone can helped you
I hope u understand ...and by the way what are you reading in school or college jab sara question brainly par he puch loge tho khud samajh kaise paoogay aur agar me bata v dunga tho tum sirf copy or book me likh lo ge tho ussse thorhe samajh jaooge
Answer:
- So, the force its N to the west.
Explanation:
The force on a charge q made by an electric field its
The electric charge of the electron its
.
Taking the unit vector pointing towards the east, the electric field will be:
.
So, the force will be:
So, the force its N to the west.
