Answer: Part of Europe, part of Africa, part of Antarctic and the entire America.
Explanation: Western hemisphere or west hemisphere encompasses all regions located west of the longitude 0 °, or meridian of Greenwich.
The formal regions located in the western hemisphere is Europe, Africa, Antarctic and America.
Answer:
The answer is below
Explanation:
Volt in physics is a term that is used to describe the unit of both electrical potential difference and electromotive force. In other words, it is a unit of measuring the voltage between two points. It is represented as "V".
The formula for Voltage is V=IR
Where V= Voltage, I = Current and R = Resistance.
Answer:
y(x, t) = A Sin(ωt ± kx)
Explanation:
Waves can be classifies as either stationary (standing), or progressive (travelling). A progressive wave is one the is a traveling wave, transferring energy along its path. While a stationary wave seems not to be moving.
The general equation for a progressive wave is;
y(x, t) = A Sin(ωt ± kx)
Where: A is its amplitude, t is the time, k is the wave number.
When the wave travels in the positive x-axis direction, the equation changes to;
y(x, t) = A Sin(ωt - kx)
When it travels in the negative x- axis direction, the equation becomes;
y(x, t) = A Sin(ωt + kx)
NB: ω = 2
f and k = 2
/λ.
Answer:
35/2 J/s
Explanation:
Just use the 2 formulas
Work done = Force * distance moved
Power = Work done/time
WD = 7 * 50 = 350
Power = 350 / 20
= 35/2 J/s
