Evgesh-ka [11]

Answer:

If possessing the ball, players must dribble (not similar to a basketball dribble), or can take up to three steps for up to three seconds at a time without dribbling. No attacking or defending players other than the defending goalkeeper are allowed to touch the floor of the goal area (within six metres of the goal).

The vectors of the magnetic field around a long, straight, current-carrying wire are:
Ksenya-84 [330]

Divide the long wire in small segments. The field due to one segment can be found from Biot- Savart law.

dB=(uo/4pi) Idlxr/r^3. In this expression if we take vector r perpendicular to current element , the cross product in the expression shows that the direction of B is perpendicular to vector r and from symmetry it can be said that field line is circular around the wire segment. This is true for all segment ,because in infinitely long wire all segments are equivalent . Thus, magnetic field lines are concentric around a long straight wire.

Hope it helps

A helium atom has a mass of mHe= 4.002604 u. When disassembled into its constituent subatomic particles (2 protons, 2 neutrons,
Paraphin [41]

Answer:

28.295244 MeV

Explanation:

m_p = Mass of proton = 1.007276 u

m_n = Mass of neutron = 1.008665 u

m_e = Mass of electron = 0.000549 u

Mass of reactant is 4.002604 u

Mass of the products is

2\times (m_p+m_n+m_e)=2\times (1.007276+1.008665+0.000549)=4.03298\ u

(2 because there are 2 of each)

The difference in mass is

4.03298-4.002604=0.030376\ u

So, the work done in MeV would be

0.030376\times 931.5=28.295244\ MeV

The work done required to completely disassemble all the helium is 28.295244 MeV
