Answer:
10 km
Explanation:
You can draw your problem out. You can use the pathagoran theorem to figure it out. So 
+ 
and then square root the answer which will be 
which equals to 10.
Sorry if this answer is a bit late...
We know that the volume of the water is 0.5 cube meters.
The density of water is 1.000 g/m^3 (that's the real density of water... maybe typos?)
The density of ice is 0.900 g/m^3 (that's the approximate density of ice)
First, let's multiply the volume of water by the density of the water to get the mass, since we know that the mass does not change with the ice gets frozen.
0.5 * 1.000 = 0.500 g
Now, let's divide that by the density of ice to get the volume of the ice.
0.500 / 0.900 = 5/9 cube meters
≈ 0.556 cube meters.
The volume of the ice is 5/9 or 0.556 cube meters.
Have an awesome day! :)

Since we're ignoring friction, we have to have a banking angle such that the normal force is exactly perpendicular to the banked curve. Since this problem says "ignore friction", if the bank angle is too shallow, the bobsled would slide outwards if the banking angle is too shallow and would fall inwards if the banking angle is too steep. So we have to exactly match the calculated centripetal acceleration.
The equation for centripetal acceleration is:
F = mv^2/r
I'll assume a mass of 1 kg to keep the math simple. Any mass could be used and the direction vectors would be the same except their magnitude would differ. So
F = 1 kg * (35 m/s)^2/100 m
F = 1225 kg*m^2/s^2 / 100 m
F = 12.25 kg*m/s^2
The local gravitational acceleration is 9.8 m/s^2, so the sum of those vectors will have a length of sqrt(12.25^2 + 9.8^2) and an angle of atan(9.8/12.25) below the horizon. The magnitude of the vector doesn't matter, merely the angle which is:
atan(9.8/12.25) = atan(0.8) = 38.65980825 degrees.
The banking angle needs to be perpendicular to the force vectors. So
90 - 38.65980825 = 51.34019175 degrees.
Rounding to 2 significant figures gives a bank angle of 51 degrees.</span>
Answer:
The environmental protection agency needs to inspect the ship and make sure it is safe before giving the ok.
Explanation:
this agency is doing its job due to they have to be sure that this ship will be sure for the marine life.
Force is used to put things in motion you can’t have motion without force!
Even if it just pushing a piece of paper you still use force to put the paper in motion!
