A cannonball of mass 15 kg is fired vertically upward from a cannon with an initial speed of 20 m/s. The cannonball travels upwa

rd, reaches a maximum height of 40 m, and returns to the ground. Now you decide to shoot a 30 kg cannonball vertically upward using the same cannon. If we assume that all cannonballs leave this cannon with an initial speed of 20 m/s, what maximum height does the 30 kg cannonball reach

Answer:

30kg ball will have equal traveling height with the 15kg

Explanation:

When air resistance is negligible, the mass of the object does not affect the maximum height or the time spent in the air.

So if mass does not affect traveling height when sir resistance is neglected...the 30kg ball will have equal traveling height with the 15kg ball provided they have equall velocities and equal angle if projection.

In this case it has 20 m/s and they are all projected vertically.

Answer pls!!
Greeley [361]

Explanation:

q= n e

6 × 10^-11 = n (1.6 × 10^-19)

n = 6×10^-11 / 1.6 × 10^-19

n= 3.75 × 10⁸ electrons

I need help understanding this concept . Would appreciate it so much. Thank you
Firlakuza [10]

Answer:

Explanation:

Both these questions are based on the Universal Law of Gravitation, which is given by :

F = Gm1m2 / r²

2) F = 6.67 x 10⁻¹¹ x 8 x 10³ x 1.5 x 10³ / 1.5 x 1.5

   F = 6.67 x 10⁻⁵ x 8 / 1.5

   F = 35.57 x 10⁻⁵ N

3) F = 6.67 x 10⁻¹¹ x 7.5 x 10⁵ x 9.2 x 10⁷ / 7.29 x 10⁴

   F = 6.67 x 10⁻³ x 7.5 x 9.2 / 7.29

   F = 63.13 x 10⁻³ N

Does passing a magnet through a coil of wire break off it’s electric current
hichkok12 [17]
A magnetic field is actually generated by a moving current (or moving electric charge specifically). The magnetic field generated by a moving current can be found by using the right hand rule, point your right thumb in the direction of current flow, then the wrap of your fingers will tell you what direction the magnetic field is. In the case of current traveling up a wire, the magnetic field generated will encircle the wire. Similarly electromagnets work by having a wire coil, and causing current to spin in a circle, generating a magnetic field perpendicular to the current flow (again right hand rule).

So if you were to take a permenant magnet and cut a hole in it then string a straight wire through it... my guess is nothing too interesting would happen. The two different magnetic fields might ineteract in a peculiar way, but nothing too fascinating, perhaps if you give me more context as to what you might think would happen or what made you come up with this question I could help.
