A 12V battery runs a 30 amp car stereo. What is the resistance of the circuit?

Airida [17]

So to find R (resistance) you do ohm's law E (volts) over I (current) to find R
So this is 12/30 = 0.4 so the resistance is 0.4

When compared to other types of waves, electromagnetic waves differ because they are

alina1380 [7]

They differ because they are transverse wave. That is their direction of travel is perpendicular to its vibrations. I'm not that sure though. Hope you get it right :).....

sladkih [1.3K]

Answer:

The larger pebble has 25 times more mass.

Explanation:

To solve the exercise it is necessary to apply the work and energy conservation equations.

For the case described, the work done must be preserved and must be the same, that is,

$W = 0$

By definition work linked to the conservation of kinetic energy would be given by

$\Delta KE = W = 0$

$\Delta KE = 0$

$KE_{larger}-KE_{smaller} = 0$

$KE_{larger}=KE_{smaller}$

$\frac{1}{2}m_lv_l^2 = \frac{1}{2}m_sv_s^2$

$m_lv_l^2 = m_sv_s^2$

The ratio between the mass and the velocity would be,

$\frac{m_l}{m_s}=\frac{v_s^2}{v_l^2}$

$\frac{m_l}{m_s} = \frac{500^2}{100^2}$

$\frac{m_l}{m_s} = 25$

Therefore the answer is: The larger pebble has 25 times more mass.
