Answer:
The cause of a magnetic force are small electrical currents or moving charges: Tiny circular currents at the atomic level are responsible in a permanent magnet for it to exert a magnetic force.
Explanation:
Answer:

Explanation:
The equation of the position is:

Where:
v(i) is the initial velocity
The initial position y(i) will be zero and the final position y = 3.60 m.
So, we just need to solve this equation for v(i).



Therefore, the initial velocity is 10.10 m/s upwards.

Density = (mass) / (volume)
Volume of your block = (5cm x 5cm x 5cm) = 125 cm³
5 gm/cm³ = (mass) / (125 cm³)
Multiply each side by (125 cm³): Mass = 625 gm
Note:
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there. The density of water ice is not
5 gm/cm³. In fact, it's a little less than 1 gm/cm³. That's why
the ice floats in your soda.
Ammonium chloride is soluble at 80g.
