Explanation:
The blocks are spinning around the center of mass, but they're also sliding horizontally. So they still have a positive displacement.
In 6 secs, the dog covers-
S=vt
8.9*6 = 53.4 m.
In the same time, the cat covers, 53.4-3.8 = 49.6 m.
Thus, speed of the cat, v= s/t,
= 49.6/6 = 8.267 m/s
A magnet is made from materials that is magnetized and create its own persistent magnetic field while a electromagnet is mad from coil of wire which acts as a magnet when electric current passes through it.
Answer:
Explanation:
1) J = P = 100 g
Mass does not change with location.
2) 10 m/s
v² = u² + 2as
0² = u² + 2(-10)(5)
3) N(ewton)
