The question is whether the statement is true or false.
The answer if false.
Explanation:
It is exactly the opposite. The soccer ball will hit the ground with greater velocity.
Since the soccer ball is thrown upward, when it returns to the same heigth from which it was throwm it will have a velocity downward, which will make that the soocer ball reaches the ground at the bottom of the clif with greater velocity than the volleball.
The greater the velocity with which the soccer ball is thrown upward, the greater its velocity when reaches the same point from which it was thrown, and the greater the velocity with which it will hit the ground at the bottom of the clif.
The answer is D) the object must move. The definition of work is movement (in any form).
Hope this helped! If it did, would you mind marking my answer as Brainliest? Thanks :D
Answer:
Mass and distance between them are two factors on which force of gravity depends
Explanation:
According to law of gravitation
Gravitational force between two object is given by
, here G is gravitational constant
are mass of the objects and r is distance between them
From the relation we can see that force of gravity is dependent on the mass of the objects and distance between them.
So mass and distance between them are two factors on which force of gravity depends
Answer:
hello the answer is 47m/s
Answer:
Work function of the metal is 3.24 eV.
Explanation:
It is given that,
Wavelength, 
Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :



Since, 
So, W = 3.24 eV
So, the work function of the metal is 3.24 eV. Hence, this is the required solution.
