The number of atoms in an element must be the same number of atoms of each element in a PRODUCT.
Answer:
<h2>30 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 15 × 2
We have the final answer as
<h3>30 kg.m/s</h3>
Hope this helps you
Answer: 40
Explanation:60kg times 2 =120 pounds
power is 40
Since this is a right-angled triangle,
Use tan 30 to find BC
Use tan 75 to find AC
Then subtract both answers to find AB
Alpha decay is one process that unstable atoms can use to become more stable. During alpha decay, an atom's nucleus sheds two protons and two neutrons in a packet that scientists call an alpha particle. Since an atom loses two protons during alpha decay, it changes from one element to another.
