The higher the dissociation constant the stronger the acid or base. Since electrolytes are created as ions are freed into solution there is a relationship between the strength of an acid, a base, and the electrolyte it produces. Acids and bases are measured using the pH scale.
Through conduction currents.
Followed by convection currents.
In the horizontal direction, the forces acting on the person are
• friction with magnitude <em>f</em>, opposing motion, and
• the horizontal component of the pulling force (itself with mag. <em>p</em> ) with mag. <em>p</em> cos(30º), in the direction of motion.
There is no friction in the vertical direction, so we omit any discussion of the vertical forces.
By Newton's second law, we then have
<em>p</em> cos(30º) - <em>f</em> = <em>m</em> <em>a</em> cos(30º)
where <em>m</em> is the person's mass, and <em>a</em> is their acceleration so that <em>a</em> cos(30º) is the magnitude of the horizontal component of acceleration. The person is pulled by a force of <em>p</em> = 401 N, so solve for <em>f</em> :
(401 N) cos(30º) - <em>f</em> = (53 kg) (0.59 m/s²) cos(30º)
<em>f</em> ≈ 320 N
Weight of the 120kg mass object on the moon
It is a fact that the gravity on the Moon is (1/6)th that on the Earth.
Assuming g ≈ 10 m/s² on the earth.
W = m*(g moon) = 120 * (10/6) = 200N.
Weight on moon = 200N.
The object would weigh approximately 200N on the moon.. The force of gravity acting on the object on the moon is the same as the weight of the object on the moon.
