Answer:
84%
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
x = 10 m
t = Time taken
= 3.5 m/s (assumed, as it is not given)
We have the equation
From continuity equation we have
Fraction is given by
The fraction is 84%
Answer:
A) E = 3.70*10^{4} N/C
B) E = 2.281*10^3 N/C
Explanation:
given data:
charge density
length of wire = 9.50 cm
a) at x = 4.5 m above midpoint, electric field is calculated as
x = 4.5 cm
midpoint a = 4.5 cm = 0.0475 m
E = 3.70*10^{4} N/C
B) when wire is in circle form
= 1.235*10^{-8} C
Radius of circle
r = 1.511*10^{-2} m
E = 2.281*10^3 N/C
Lessening frictions Means it harder to stop
Answer:
the Earth magnetic field in that region is about 89.09 T
Explanation:
If the magnetic field has an inclination of , and its horizontal component is 17 microTesla, then we can calculate the magnitude of the full magnetic field via the cosine function. Notice that the decomposition of a vector in horizontal and perpendicular components originates a right angle triangle where the vector is the hypotenuse of the triangle.
The speed of the wave with the given frequency and wavelength is 1.2m/s.
Given the data in the question;
- Wavelength of the wave;
- Frequency;
- Speed of the wave;
<h3>
Wavelength</h3>
Wavelength is the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
It is expressed as;
Where v is velocity/speed and f is frequency.
Now, we can easily get the speed of the wave by substituting our given values into the expression above.
Therefore, the speed of the wave with the given frequency and wavelength is 1.2m/s.
