What determines the composition of a rock
Answers
Composition of a rock is determined by the percent of constituent of minerals and elements contained within it.
Explanation:
The composition of a rock is decided by the % of the constituent minerals and components contained inside it.
The minerals that form up rocks have outlined chemical compositions and rigid atomic structures. once daylight strikes the rock's surface, the composition and atomic structure of the various minerals management the wavelengths they absorb or replicate.

Answer:
3.06 seconds
Explanation:
To find the maximum height above the ground level, we can use the kinematic equation for vertical motion. The equation is:
h = (v^2 - u^2) / (2g)
Where:
h is the maximum height,
v is the final velocity (which is 0 when the ball reaches its highest point),
u is the initial velocity (30 m/s),
and g is the acceleration due to gravity (approximately 9.8 m/s^2).
Plugging in the values, we get:
h = (0^2 - 30^2) / (2 * 9.8)
Simplifying the equation gives us:
h = -900 / 19.6
The maximum height above the ground level is approximately -45.92 meters. Since the height cannot be negative, the maximum height is 45.92 meters.
To find the time it takes for the ball to reach the ground, we can use another kinematic equation:
t = (v - u) / g
Where:
t is the time,
v is the final velocity (which is 0 when the ball reaches the ground),
u is the initial velocity (30 m/s),
and g is the acceleration due to gravity (approximately 9.8 m/s^2).
Plugging in the values, we get:
t = (0 - 30) / 9.8
Simplifying the equation gives us:
t = -30 / 9.8
The time it takes for the ball to reach the ground is approximately -3.06 seconds. Since time cannot be negative, the ball takes approximately 3.06 seconds to reach the ground.

Answers
Answer:
Car C
Explanation:
It is given that,
Five race cars speed toward the finish line at the Jasper County Speedway. The mass of each car has same mass. The speed of all cars are given as :
Car A = 890 m/s
car B = 850 m/s
Car C = 790 m/s
Car D = 895 m/s
Car E = 870 m/s
The distance is constant because the finish line is same for all cars. The speed of an object is given by the total distance covered divided by total time taken i.e.
Where
d = distance
t = time required by the car to come to a full stop
So, time taken is inversely proportional to the speed of the car. The car having less speed will take maximum time to come to stop. Hence, car C will require longest time to come to a full stop.
Answer:
Car D
Explanation:
The mass of the car is given the same. The initial velocities are also given. eventually all the cars come to a stop. The finish line would be crossed first by the fastest car. But If all the cars decelerate at the same rate then, we can find out the time taken to come to a full stop by first equation of motion,
final velocity, v = 0
if a is same for all cars.
Car D has maximum speed ( 895 m/s). So, Car D will take the maximum time to come to a stop.

Answer:
Car B
Explanation:
Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.
According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.
The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.

Answer:
B.endangered
Explanation:
Choose "extinct" if the species is extinct and "endangered" if the species is endangered.
Sixty years ago, as few as 20 whooping cranes were left on earth. Now, thanks to conservation efforts, there are more than 300 whooping cranes in the wild.
A.extinct
B.endangered
if there are 20 whooping cranes sixty years ago, and then we have more than 300 today. then it means that the species are endangered
I will go with B
An extinct species no longer exist because there are no offsprings of the parent specie which can give birth to more subspecies .
species no longer exist anywhere on Earth, and once gone they are gone ... on International Trade In Endangered Species like Wild Fauna and Flora (CITES). .... in 1975; the species now numbers more than 1, 000 animals .... whooping cranes, this approach fails to protect most endangered species
Endangered means that the existence is threatened by some human activities, prevailing conditions in the environment or the host it feeds on to survive no longer exists within it reach, hence its survival is at stake
