Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl.
<span>F = GMm/r^2
but we don't want force we want acceleration.
F = ma
combining the two
ma = GMm/r^2
cancelling m from both sides
a = GM/r^2
where G is the universal gravitational constant M is the mass of Saturn and r is the radius of Saturn.
g(Saturn) = a = (6.67x10^-11m^3kg^-1s^-2)(5.68x10^26 kg)/(5.82x10^7m)^2
g = 11.18 m/s^2 round to 11.2 m/s^2</span>
Answer:
C.
Explanation:
Exothermic refers to a RELEASE of energy through a reaction(usually chemical). When salt dissociates, polar water molecules pull apart ions, releasing energy.
Answer:
106.25 m
Explanation:
Acceleration a = force / mass
= 40 / 80 = 0.5 m /s²
initial velocity u = 20 m /s
a = 0.5 m /s²
time t = 5 s
displacement s = ?
s = ut + 1/2 a t²
= 20 x 5 + .5 x .5 x 5²
= 100 + 6.25
= 106.25 m .
Answer:
a) 
b) 
Explanation:
Given:
height of water in one arm of the u-tube, 
a)
Gauge pressure at the water-mercury interface,:
we've the density of the water 
b)
Now the same pressure is balanced by the mercury column in the other arm of the tube:
<u>Now the difference in the column is :</u>
