All particles madeup of two or more quarks held together by a force are called ; ( C ) Hadrons
Hadrons are subatomic particles which are made of two or more quarks which are held firmly by a force similar to electric force. An example of Hadron is Baryon which contains three quarks which are held closely together.
Hence we can conclude that All particles made of quarks are called Hadrons

Answer:
All particles made of quarks are called hadrons.
The forest ecosystem will regain back its natural ecology compared to burning of the forest and other illegal activities done to the forest. And also, some of the animals living in that forest will live and those that are endangered will not be threatened.
h2 would be very large?
2) Without using equations, explain why making h2 very small would cause d to be small, even though
h1 would be large
B) Derive an equation for d in terms of h1, h2, m, and physical constants as appropriate.
(A)
(1) The reason for making very small is due to smaller value of horizontal component of launch velocity.
(2) The reason for making very small is due to smaller value of time of flight.
(B) The distance (d) covered by the block is .
Given data:
The mass of block is, m.
The height of table from the top of slide is, .
The height of table at the end of slide is, .
The height of room is, H.
(A)
(1)
If the launch velocity of the block is v, then its horizontal component is very small, due to which adjusting the height to be very small will cause the d to be small.
(2)
The height is dependent on the time of flight, and since the time of flight taken by the block to get to the floor is very less, therefore the block will not get sufficient time to accomplish its horizontal motion. That is why making very small will cause d to be smaller.
(B)
The expression for the distance covered by the block is,
..............................(1)
Here, v is the launch speed of block and t is the time of flight.
The launch speed is,
And the time of flight is,
Substituting the values in equation (1) as,
Thus, the distance (d) covered by the block is .

A1) The reason why making h₁ very small would cause d to be small is; Because the horizontal component of the launch velocity would be very small.
A2) The reason why making h₂very small would cause d to be small is;
Because the time of flight it will take the object to get to the floor would be very small and as a result, the object would not possess enough time to move horizontally before the vertical motion.
B) The equation for d in terms of h₁ and h₂ is;
d = 2√(h₁ × h₂)
A) 1) The reason why making h₁ very small would cause d to be small is because the horizontal component of the launch velocity would be very small.
A) 2) The reason why making h₂ very small would cause d to be small is because the time of flight it will take the object to get to the floor would be very small and as a result, the object would not possess enough time to move horizontally before the vertical motion.
B) Formula for Launch Velocity is;
V = √(2gh₁)
h₁ was used because the top of the slide from where the student released the block has a height of h₁.
Also, the time it takes to fall which is time of flight is given by the formula;
t = √(2h₂/g)
h₂ was used because the height of the table the object is on before falling is h₂.
Now, we know that d is distance from edge of the table and formula for distance with respect to speed and time is;
distance = speed × time
Thus;
d = √(2gh₁) × √(2h₂/g)
g will cancel out and this simplifies to give;
d = 2√(h₁ × h₂)

b. just above Earth's surface
c. on Earth's surface
The acceleration of gravity at the surface of the Earth is approximately 9.8 meters (32 feet) per second per second. As a result, during free fall, an object's speed rises by around 9.8 meters per second.
The force that binds all masses in the universe together, particularly the pull of the earth's mass on objects that are close to its surface.
The term gravitational force refers to the force that the earth exerts on a body. Examples of motion caused by gravitational force include the downward motion of water in a river, the downward motion of water in a stream, and the upward motion of a ball when it is thrown.
All physical things with mass are drawn to the gravitational force, which can be thought of as an attracting force. It is the known natural force that is by far the weakest. representation in mathematics. The formula for gravitational force is F = G m 1 m 2 r in mathematics.
The answer is on earth surface
