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.

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

A thin conducting square plate 1.0 m on the side is given a charge of-2.0 x 10-6 c. A proton is placed 1.0 en above the center o

adell [148]

Answer:

Acceleration, $a=1.08\times 10^{13}\ m/s^2$

Explanation:

It is given that,

Side of the square plate, l = 1 m

Charge on the square plate, $Q=-2\times 10^{-6}\ C$

Position of a proton, x = 1 cm

The electric field due to a parallel plate is given by :

$E=\dfrac{Q}{2A\epsilon_o}$

Electric force is given by :

F = q E

$F=\dfrac{Qe}{2A\epsilon_o}$

e is the charge on electron

The acceleration of the proton can be calculated as :

$a=\dfrac{F}{m}$

m is the mass of proton

$a=\dfrac{Qe}{2A\epsilon_o m}$

$a=\dfrac{2\times 10^{-6}\times 1.6\times 10^{-19}}{2(1)^2\times 8.85\times 10^{-12}\times {1.67\times 10^{-27}}}$

$a=1.08\times 10^{13}\ m/s^2$

So, the acceleration of the proton is $1.08\times 10^{13}\ m/s^2$ . Hence, this is the required solution.

On a hot summer day, heat waves can be seen rising from the asphalt. What type of heat transfer do the heat waves demonstrate?

Semenov [28]

There are three types of heat transfer namely convection, conduction and radiation. For this situation, the heat waves seen from the asphalt is an example of heat transfer called radiation. Radiation is the transfer of heat energy by electromagnetic radiation. The heat from the sun absorbed by the asphalt is called the radiant energy which causes it to emit heat waves.

postnew [5]

Answer:

B.KEEN EYESIGHT thats for predators !

Explanation:

Herbivores have multiple stomachs to process tough foods, coats to blend in so they don't get eaten, and tough teeth for chewing on the plants. THEY DO NOT HAVE PREY, THEY ARE THE PREY.
