Answer:
Explanation:
As we know that electrostatic potential energy of the electron is converting here into kinetic energy
so we will have
so here we know that
so from above equation we have
Herz is a measurement for how many cycles of the wave occur per second, which in this case is 261. the period is the time it takes to complete 1 cycle, so if 261 cycles occur per second, one cycle occurs every 1/261 seconds
Answer:
≈147.86 (m.)
Explanation:
1) if the acceleration is a=(V-V₀)/t, where V₀ - initial velocity (25), V - final velocity (2), t - elapsed time, then
t=(V-V₀)/a=23/2.1 (sec.);
2) the required distance can be calculated according to the formula:
S=V₀t+0.5(at²), where V₀=25; t=23/2.1; a= -2.1;
3)
A weight explanation is the volume of density of a particular substance has to be weight…
During the period of constant acceleration, the car's average speed is (1/2) (16 + 32) = 24 m/s.
At that average speed, it covers 240 meters in 10 seconds.
