Using the equation for the final velocity in terms of masses and initial velocity of the gliders for a perfectly inelastic colli

tatuchka [14]

Answer:

Comparison has been made.

Explanation:

Consider perfectly inelastic collision.Two masses of m1 and m2 with initial velocities u1 and u2 before colliding, stick together after collision and move with common speed v. then according to the rule of momentum preservation

m1u1+m2u2= (m1+m2)v

$v= \frac{m1u1+m2u2}{m1+m2}$

If u1 and u2 are known the final common velocity can be determined

Initial kinetic energy is

$\frac{1}{2}m1u1^{2}+\frac{1}{2}m2u2^{2}$

The collion here is perfectly inelastic this means kinectic energy is not conserved. Therefore, initial kinectic energy is not equal to final kinectic.

$\frac{1}{2}m1v^{2}+\frac{1}{2}m2v^{2}$

Which are methods of reducing exposure to ionizing radiation? Check all that apply

MariettaO [177]

Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.

An investigator places a sample 1.0 cm from a wire carrying a large current; the strength of the magnetic field has a particular

AURORKA [14]

Answer:

she must increase the current by factor of 7

Explanation:

The magnetic field produced by a steady current flowing in a very long straight wire encircles the wire.In order to solve the question, we use this formula,

B= μo I/(2πr)

where,

'μo' represents permeability of free space i.e 4π*10-7 N/A2

B=magnetic field

I= current

r=radius

->When r= 1cm=> 0.01m

B1 = μo $I_{1$ /(2π x 0.01)

->when r=7cm =>0.07m

B2 = μo $I_{2}$ /(2π x 0.07)

Now equating both of the magnetic fields, we have

B1= B2

μo $I_{1$ /(2π x 0.01)= μo $I_{2}$ /(2π x 0.07)

$I_{1$ / $I_{2}$ = 0.01/0.07

$I_{1$ / $I_{2}$ = 1/ 7

Therefore, she must increase the current by factor of 7
