Answer:

1.4 m/s

Explanation:

The final velocity of the ball can be found by using the following SUVAT equation:

$v^2-u^2=2ad$

where

v is the final velocity

u is the initial velocity

a is the acceleration

d is the distance travelled

In this problem,

u = 4.0 m/s

d = 14 m

a = -0.50 m/s^2

Solving the equation for v,

$v=\sqrt{u^2+2ad}=\sqrt{4^2+2(-0.50)(14)}=1.4 m/s$

Exercise 15.1 (a) Find the magnitude of the electric force between two protons separated by 1 femtometer (10^-15), approximately

Goryan [66]

Answer:

(a) 230.4 N

(b) $a = 1.38\times10^{29} m/s^{2}$

Explanation:

Charge on a proton, q = $1.6\times10^{-19}C$

Distance between the two protons, d = 1 femto meter = $1\times10^{-15}m$

(a) By use of coulomb's law, the force between the two protons is given by

$F =\frac{k\times q\times q}{d^{2}}$

Where, k is the Coulombic constant = 9x 10^9 Nm^2/C^2

So, the force between them is given by

$F =\frac{9\times10^{9}\times 1.6\times10^{-19}\times 1.6\times10^{-19}}{\left (1\times10^{-15} \right )^{2}}$

F = 230.4 N

(b) Acceleration is the ratio of force to the mass of proton.

the mass of proton, m = 1.67 x 10^-27 kg

So, acceleration

$a=\frac{230.4}{1.67\times10^{-27}}$

$a = 1.38\times10^{29} m/s^{2}$

You can see lightning before you can hear the thunder. Which is the best explanation for this?

liubo4ka [24]

Salutations!

<span>You can see lightning before you can hear the thunder. Which is the best explanation for this?

The best explanation for this statement is the transmission of light in air is faster than the transmission of sound in the air. Light is faster than sound, thus you can see the thunder then you can hear the sound.

Hope I helped :D</span>
