The answer is c. The amount of matter in an object is the concentration of the atoms inside. This can also be called density. Weight depends on density because weight =

<em>The main cause of twice-daily tides around the world are;</em>
Gravitational pull of the moon
<u>Tides are the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth. </u>
<u>The moons gravity is large enough to actually pull water out of the ocean from space. Just enough to create motion of the tides.</u>
Answer:
The minimum possible coefficient of static friction between the tires and the ground is 0.64.
Explanation:
if the μ is the coefficient of static friction and R is radius of the curve and v is the speed of the car then, one thing we know is that along the curve, the frictional force, f will be equal to the centripedal force, Fc and this relation is :
Fc = f
m×(v^2)/(R) = μ×m×g
(v^2)/(R) = g×μ
μ = (v^2)/(R×g)
= ((25)^2)/((100)×(9.8))
= 0.64
Therefore, the minimum possible coefficient of static friction between the tires and the ground is 0.64.
