Answer:
A bicycle.
Explanation:
A compound machine is a machine consisting of multiple simple machines.
A bicycle contains 3 simple machines. A lever, pulley, and wheel-and-axle.
all other choices are simple machines.
Hope this helps!

The definition of dilute is "make (a liquid) thinner or weaker by adding water or another solvent to it." Now, this may make you think that the beaker with three scoops is the most dilute, but it's not. In this case, it depends on the salt to water ratio. Let's say each beaker contains five parts water. The first beaker has a ratio of 1/5. The second had a ratio of 2/5. The third has a ratio of 3/5. To find which has the most water compared to the others, I'll use equal to make the numerator (The amount of salt) seemingly equal each time. Just a warning, this strategy doesn't work every time. Now, if we make the numerators the same, that means which ever denominator is the highest will be the most dilute solution. Let's make each numerator equal to six, as each number (1, 2, and 3) go into six.
1/5 = 6/30
2/5 = 6/15
3/5 = 6/12
I got these numbers by dividing six (What we want the numerator to be) by each current numerator, and then multiplying the quotient (The answer of a division problem) by both sides of the fraction. Since the first beaker has the highest denominator, we know that it is the most dilute.

Options:
a) 10 m/s²
b) 8 m/s²
c) 4.4 m/s²
d) More information is needed
Answer:
d) More information is needed
Explanation:
The acceleration due to gravity at an altitude h above the surface of a planet is given by the equation:
.................(1)
where the altitude above the surface of the planet X, h = 3000 km
Acceleration due to gravity at the surface of the planet, g₀ = 10 m/s²
To be able to get the acceleration due to gravity, g, at an altitude h above the surface of the planet, all parameters must be substituted into equation (1).
Unfortunately, the radius, R, of the planet, X, is not given. This means that there are no sufficient parameters(information) to find the acceleration due to gravity at an altitude h above the surface of the planet.
