Answer:
1) solvent
2) liquid-solid
3) gas - gas
Explanation:
1) A solution is the homogenous mixture of two or more substances in such a way that its components are uniformly distributed. In any solution, the solvent make up the greatest quantity or volume while the solute is of lesser quantity.
2) liquid-solid is the most common type of solution.
3) A gas solution can be a gas dissolved in a gas, or a liquid dissolved in a gas, or a solid dissolved in a gas. Air is a gas - gas solution, it is composed of oxygen and other dissolved gases in nitrogen
Answer: liquid
explanation: 1 liter is a measurement of liquids, not solids, or gases.
Liquids also have a set volume, but can flow to take the shape of the bottom of their container.
Answer:
We conclude that the centripetal force needed to keep a 7kg mass moving in a circle of 4 meters radius at 15m/s is 393.75 N.
Explanation:
Given
To determine
We need to determine the centripetal force needed to keep a 7kg mass moving in a circle of 4 meters radius at 15m/s.
We know a centripetal force acts on a body to keep it moving along a curved path.
We can determine the centripetal force using the formula

where
is the mass
is the velocity
is the radius
is the centripetal force
substitute m = 7, r = 4, and v = 15 in the formula



N
Therefore, we conclude that the centripetal force needed to keep a 7kg mass moving in a circle of 4 meters radius at 15m/s is 393.75 N.
Answer:
The equations are :
h = 18 + 1.5t
h = 5 + 24t - 16t^2
Explanation:
Speed = distance/time
1.5ft/s = 18ft/t
1.5t=18
The equation to determine height h= 18 + 1.5t
Graham moved another 5ft further with a velocity of 24ft/s
The equation to determine his height will be:
h= 5 + 24t -16t^2
The formula you use is Density = (mass) / (volume) .
The calculation for this particular object is
Density = (68.895 g) / (23.5 mL - 14.7 mL)
Density = (68.895 g) / (8.8 mL)
<em>Density = 7.8 g/mL</em>
