Answer:

d. Wave Height

Explanation:

Imagine my crude drawing of a sea wave is actually passable haha, so, the top of the wave is called the crest, and the lowest part of the wave, under the calm sea level, is the Trough, the vertical distance between those two points is the wave height.

As extra credit ;) the distance between two consecutive crests or two consecutive troughs is the wavelength, and this is exactly the same in radio waves!

An arrow is launched with an initial velocity of 7.6 m/s at an angle of 42 degrees above the horizontal. What is the horizontal
AleksAgata [21]

Explanation:

At any point on the arrow's trajectory, the horizontal component of the velocity is the same. Therefore, the horizontal component of the velocity at the top of its trajectory is

v_x = v_{0x} = v_0\cos{42°} = (7.6\:\text{m/s})\cos{42°}

\:\:\:\:\:=5.6\:\text{m/s}

1.80 kJ of heat is added to a slug of gold and a separate 1.80 kJ of heat is added to a slug of manganese. The heat capacity of
Svetlanka [38]

Answer:

final temperature of  slug of gold is 37°C

final temperature of  slug of manganese is 28.56°C

Explanation:

Hello! To solve this problem we must take into account the concept of heat capacity, this is defined as the ratio between energy and temperature rise.

In other words it is the amount of energy that is required to increase a temperature degree.

Taking into account the above we infer the following equation

where  

C=heat capacity
