Answer:

Elastic collision

Explanation:

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. Supposed two similar trolleys are traveling toward each other with equal speed.

What is the frequency of a sound wave that has a wave length of 3.5 m?

polet [3.4K]

Answer:

85.654988MHz

Explanation:

f = C/λ

λ (Lambda) = Wavelength in meters

c = Speed of Light (299,792,458 m/s)

f = Frequency (MHz)

299,792,458 m/s. ÷ 3.5. = 85.654988MHz

A solenoid with 1000 turns has a cross-sectional area of 7.0 cm2 and length of 25 cm. How much energy is stored in the magnetic

Nimfa-mama [501]

Answer:

The energy stored in the solenoid is 0.18J

Explanation:

We need to obtain the inductance in order to calculate the energy:

$L=\µ_o*N^2*\frac{A}{L}\\\\L=4*\pi*10^{-7}*1000^2*\frac{(7.0*10^{-4}m^2)}{25*10^{-2}m}\\L=3.51mH$

The energy stored in the solenoid is given by:

$U_g=\frac{1}{2}*L*i^2\\\\U_g=\frac{1}{2}*3.51*10^{-3}*10.0^2\\\\U_g=0.18J$

What must happen to the electrons in a material to create an electric current?

Nesterboy [21]

<span>The electrons need to migrate from a region of lower electric potential to a region of higher electric potential. This flow of electrons is known as electron current (which is contrary to the widely-accepted perspective of conventional current).</span>
