Physics
1 answer:
katrin2010 [14]3 years ago
5 0

Answer:

If you change the number of neutrons in an atom, you get an isotope of the same element. The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element.

Reil [10]

Complete question

A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon?

A   0.0 m/s

B    250. m/s

C   433 m/s

D    500. m/s

Answer:

The correct option is  C

Explanation:

From the question we are told that

   The velocity is  v  = 500 \ m/s

    The angle is  \theta = 30^o

   

Generally the vertical component of the canon ball is mathematically represented as  

          v_y = v * cos (30 )

=>       v_y = 500 * cos (30 )

=>       v_y = 433 \ m/s
