Answer:
a). Single replacement.
Explanation:
Because one element replaces another element in a compound
Hi there!
We can use the rotational equivalent of Newton's Second Law:
Στ = Net Torque (Nm)
I = Moment of inertia (kgm²)
α = Angular acceleration (rad/sec²)
We can plug in the given values to solve.
Without magnetic domains a magnet would have its magnetism. Magnetic domains are clusters of iron atoms that line up in the same direction when magnetized. When not magnetized the iron atoms scatter.
Answer:
As the Ballon pulls up, the distance between the Ballon and the center of the earth increases, the gravitational pull reduces and the gravity potential energy increases.
Explanation:
Given parameters:
Frequency = 12Hz
Unknown:
a. Period of its rotation
b. Time required to complete 86 rotations
Solution:
Frequency is the number of times of rotation per unit of time.
Frequency =
Period is the opposite of frequency;
Period = = 0.083s
b. Time for 86 rotations;
Since frequency =
n is the number of rotation
t is the time
t = = = 7.2s
