Extinct because it will die if it don’t adapt or evolve to its surroundings
Answer:
0.79 s
Explanation:
The initial velocity of the ball is, .
And now we know that first equation of motion.
Here, v is the final velocity, u is the initial velocity, t is time taken by the object, a is the acceleration.
Given that, final velocity is zero and ball is inb upward direction means opposite to acceleration due to gravity which means a=-g. and the value of g is
Therefore,
Therefore, it is the required minimum time that player must waiot to touch the ball.
Watch in the diagram above that a downward vector will provide a partial or full cancellation of an upward vector.
And a leftward vector will provide a partial or full cancellation of a rightward vector.
In this case, as the meanings of the vectors are opposite, one of the forces receives the negative signal and thus a piece of the other vector is drawn, as shown in the figure. And to know the module of the resultant force, if it subtracts the modules of the forces.
Answer:
(in order to have a net force of 8 N, right) B. 8 Newtons
Explanation:
According to Dalton's atomic theory, all the atoms are individual, all the atoms of the same element are identical in properties and mass, the compound is formed from two or more kinds of the atoms, all the matter is made up of small atoms and the chemical reaction is a rearrangement of the atoms.
The discoveries which contradicts the components of Dalton's atomic theory from the given discoveries are:
Nuclear reactions can change an atom of one element into an atom of another element.
Atoms of a given element can have different numbers of neutrons.
Atoms contain smaller particles: protons, neutrons, and electrons.
