Answer:
H=1020.12m
Explanation:
From a balance of energy:
where H is the height it reached, d is the distance it traveled along the ramp and Ff = μk*N.
The relation between H and d is given by:
H = d*sin(30) Replace this into our previous equation:

From a sum of forces:
N -mg*cos(30) = 0 => N = mg*cos(30) Replacing this:
Now we can solve for d:
d = 2040.23m
Thus H = 1020.12m
The total charge passing a given point in the conductor from t = 0 to t = 1/240 s is 12000π Coulombs
<h3>Total charge through a conductor</h3>
A conductor is a substance that allow current and electricity to pass through it.
The expression that will be used to calculate the current is expressed s:
I(t) = 100 sin (120πt)
where
I is in amperes and t is in seconds.
Since dQ = Idt = I(t) = 100 sin (120πt)
On integrating
Q = 100*120πcos(120πt) |¹/¹²⁴⁰₀
Substitute the limits
Q = 100 * 120π
Q = 12000π Coulombs
Hence the total charge passing a given point in the conductor from t = 0 to t = 1/240 s is 12000π Coulombs

Answer:In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Answer:
A 20 Hz sound wave is 75 m long in the water (1500/20 = 75) whereas a 20 Hz sound wave in air is only 17 m long (340/20 = 17) in air. As we descend below the surface of the sea, the speed of sound decreases with decreasing temperature.
