A volleyball is dropped from a cliff and a soccer ball is thrown upward from the same position. When each ball reaches the groun
vredina [299]
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.

What two factors determine the force of gravity between two objects?
Yuki888 [10]

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 F=\frac{Gm_1m_2}{r^2}, here G is gravitational constant m_1\ and\ m_2 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

Photoelectrons are observed when a metal is illuminated by light with a wavelength less than 383 nm. What is the metal's work fu
Ulleksa [173]

Answer:

Work function of the metal is 3.24 eV.                                    

Explanation:

It is given that,

Wavelength, \lambda=383\times 10^{-9}\ m

Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :

W=\dfrac{hc}{\lambda}

W=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{383\times 10^{-9}}

W=5.193\times 10^{-19}\ J

Since, 1\ eV=1.6\times 10^{-19}\ J

So, W = 3.24 eV

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