Answer:
Natural selection is a mechanism, or cause, of evolution.
Explanation:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
Apply Boyle's law:
PV = const.
P = pressure, V = volume, the product of P and V must stay constant
Our initial P and V values are:
P = 0.52atm, V = 5.7L
Our final P and V values are:
P = ?, V = 2.0L
Set the products of each set of PV values equal to each other and solve for the final P:
P(2.0) = 0.52(5.7)
P = 1.48atm
Answer:
3.13cm/s²
Explanation:
Given
Initial velocity u = 3.5cm/s
Final velocity v = 8.2cm/s
Time t = 1.5secs
Required
Acceleration of the cart a
To get that, we will use the equation of motion
v = u+at
Substitute the given parameters
8.2 = 3.5+1.5a
1.5a = 8.2-3.5
1.5a = 4.7
a = 4.7/1.5
a = 3.13cm/s²
Hence the acceleration to the cart is 3.13cm/s²
To identify which one is ionic compound, you would select the compound with the high melting point. Ionic compounds<span> have high </span>melting points<span> because the electrostatic interactions that hold the compounds together are very strong. Hope this answers the question.</span>
Answer;
By using kepler's 3rd law we find that;
-A year on Earth is shorter than a year on Saturn.
Explanation;
-Kepler’s 3rd law states that the square of a planet’s orbital period is proportional to the cube of its average distance from the Sun (semi-major axis), which tells us that more distant planets move more slowly in their orbits.
-In other words, if you square the 'year' of each planet, and divide it by the cube of its distance to the Sun, you get the same number, for all planets. The law captures the relationship between the distance of planets from the Sun, and their orbital periods.
