Answer:
<h2>The answer is 2.5 m/s²</h2>
Explanation:
The acceleration of an object given it's velocity and time taken acting on it can be found by using the formula
From the question
time = 4 s
velocity = 10 m/s
So we have
We have the final answer as
<h3>2.5 m/s²</h3>
Hope this helps you
Answer:
6. 9.4 m
7. 1050 m/s.
Explanation:
6. Determination of the wavelength
Velocity (v) = 30 m/s
Frequency (f) = 3.2 Hz
Wavelength (λ) =?
v = λf
30 = λ × 3.2
Divide both side by 3.2
λ = 30 / 3.2
λ = 9.4 m
Thus, the wavelength of the wave is 9.4 m.
7. Determination of the speed of the wave.
Wavelength (λ) = 350 m
Frequency (f) = 3 Hz
Velocity (v) =.?
v = λf
v = 350 × 3
v = 1050 m/s
Thus, the speed of the wave is 1050 m/s
A coil of wire with a current flowing thru it becomes a magnet
Answer:
Both technicians are correct.
Explanation:
Printed circuits boards are copper layers attached to a dielectric plane with some design on it. This design is made to direction the current flow through a predefined path or electrical circuit. This way is easier to interconnect electronic devices instead of using cables for each connection.
Since the printed circuit board PCB its made of cooper, touching the printed circuit board may cause in the middle term corrosion and even rust, because the cooper in touch with the salt, sweat, and other stuff from the fingerprints can react in the metal surface, creating corrosion.
