A testing instrument that's used to measure electrical signals
in a circuit and display them as waveforms on a screen is called
an oscilloscope.
Most countries besides the USA use the metric system also known as S.I (system internationale) as a system of measurement...
Answer:
72.54 degree west of south
Explanation:
flow = 3.9 m/s north
speed = 11 m/s
to find out
point due west from the current position
solution
we know here water is flowing north and ship must go south at an equal rate so that the velocities cancel and the ship just goes west
so it become like triangle with 3.3 point down and the hypotenuse is 11
so by triangle
hypotenuse ×cos(angle) = adjacent side
11 ×cos(angle) = 3.3
cos(angle) = 0.3
angle = 72.54 degree west of south
Answer: The correct option is B.
Chromosomes contain genes that tell the body how to grow and work.
Explanation:
This is because chromosomes contain alot of human genes which are found in the nucleus and every humans have 23 pairs of chromosomes. The sets of genes determines some of the body features, characteristics or traits. The genes in the body form the genotype and the genotype is expressed physically which is now the phenotype i.e traits expressed physically in the body which is an indication of body appearance.
The correct option is (A) 2.5 m/s
Explanation:
Since,
v = fλ ---- (1)
where v = speed of the wave
f = frequency of the wave = 5 Hz
λ = wavelength of the wave = 0.5
Plug in the value in (1):
(1) => v = 5 * 0.5
v = 2.5 m/s
