A positive charged atom has lost electrons.

Electrons are present in the outer shell of an atom, loosely bond to the nucleus, the only binding force on the electrons is the electric force, while the protons are inside the nucleus, and tightly bond to the nucleus by nucleus binding force, therefore an atom can only be positively charged when it loose electron from the shall.

What happens when the wire in an electromagnet is wrapped around a soft iron core?
Pavlova-9 [17]
The magnetic particles in a soft iron nail will line up with the magnetic field when the current is switched on. ... When you switch on the current, the coil becomes an electromagnet. But also, the soft iron core becomes a magnet. It will add to the strength of the electromagnet.

A 1.0-kg cue ball traveling at 15 m/s strikes a stationary billiard ball of mass 1.5 kg. After the collision, the cue ball remai
Igoryamba

Answer:

Other ball's velocity is 10 m/s

Explanation:

We can use conservation of momentum:

P_{1i} +P_{2i} =P_{1i} +P_{2i}\\1 * 15 + 1.5 * 0 = 1 * 0 + 1.5 * v\\15 = 1.5 * v\\v=\frac{15}{1.5} \,\frac{m}{s} \\v=10 \,\frac{m}{s}

An Alaskan rescue plane traveling 39 m/s drops a package of emergency rations from a height of 198 m to a stranded party of expl
Elden [556K]

y = 0m

y0 = 166m

v0y = 0 m/s

g = 9.8 m/s^2

t = ?


Solve for t:

y = y0 + v0y*t - (0.5)gt^2

0 = 166 - (0.5)(9.8)t^2

t = 5.82 s


Now, using time, we can solve for the range using the equation:


x = vx(t)

x = (40)(5.82)

x = 232.8 m


The impact horizontal component of velocity will be 40 m/s as velocity in terms of x is always constant. To find the impact vertical component of velocity, we use the equation:


v = v0y - gt

v = 0 - (9.8)(5.82)

v = -57.04 m/s
