As a result, although the Moon is moving to the east relative to the stars, the much faster westward motion of the sky is carrying it to the west, so despite its eastward motion relative to the center of the Earth, it rises in the east and sets in the west, just like any other celestial body.
Answer:
a. 3.0 m/s^2
b. 18N
Explanation:
force = mass times acceleration
a.
box 1
24 = 2 times acceleration
24 divided by 2 = acceleration
acceleration = 24 divided by 2
acceleration = 12
box 2
24 = 6 times acceleration
24 divided by 2 = acceleration
acceleration = 24 divided by 6
acceleration = 4
acceleration is averaged
(2+4)/2 = 3

b.
its saying
in f = ma
if you have the same m of 6
and the a of 3
what is the force?
6 times 3 = 18
18 N
Answer:
Explanation:
If V be the potential difference which creates velocity v
Ve = 1/2 m v²
e is charge on the particle , m be the mass .
If V is tripled , v becomes √3 times , so velocity becomes √3 v .
in magnetic field , the path becomes circular
for radius of the circle , the relation is
m v² / R = Be v , B is magnetic field
R = m v / B e
So R is proportional to velocity
If velocity becomes √3 times , radius too becomes √3 times
new radius = √3 x 5
= 8.66 cm.
b )
For angular frequency ω = v / r = velocity / radius
velocity = 5 x 10⁴ m / s , r = 8.66 x 10⁻² m
= 5 x 10⁴ / 8.66 x 10⁻²
= .577 x 10⁶ rad / s
= 5.77 x 10⁵ rad / s
Frequency is inversely proportional to wavelength.
Wavelength is the spacial period, and more generally the frequency is inversely proportional to the period.
If the wave's speed if c, then f=c/l where l is the wavelength.
Answer:
The capacitance is 11 F for half and fully charged capacitor.
Explanation:
Capacitance of capacitor is given by the expression
Where ε is the vacuum permittivity, A is the area of plates and d is the separation between plates.
So capacitance does not depend upon charge and potential. So capacitance fully and half charged capacitors are same.
Here the capacitance is 11 F for half and fully charged capacitor.
