The magnetic forces exerted by the magnet can act at a distance on other magnets or on objects containing certain metals. The magnetic fields showcase the presence of magnetic forces. The magnetic forces arise due to attraction and repulsion of the poles inside the material. Opposite poles attract each other while similar poles repel each other.
Answer:
compound is formed .............
Explanation:
mass = Moles * molar mass
molar mass of BaSO4 = 112+32+64= 208
= 1.72*208 = 357.76
Answer:
<h2>69,480 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 = 45 × 1544
We have the final answer as
<h3>69,480 kg.m/s</h3>
Hope this helps you
