Answer:
Explanation:
Area A of the coil = .1 x .1 = .01 m²
no of turns n = 5
magnetic field B = .5 t²
Flux Φ perpendicular to plane passing through it.= nBA sin30
rate of change of flux
dΦ/dt = nAdBsin30 / dt
= nA d/dt (.5t²x .5 )
= nA x 2 x .25 x t
At t = 4s
dΦ/dt = nA x 2
= 5x .01 x 2
= .1
current = induced emf / resistance
= .1 / 4
= .025 A
= 25 mA.
Answer:
11
Explanation:
According to Boyle's law:
Thus,
Where, n is the number of the balloons
From the question, it is given that:
For balloon:
P = Pa
V = 0.040 m³
For cylinder:
P = Pa
V = 0.0031 m³
So,
n = 11.625
<u>So, Maximum number of balloons = 11</u>
By the use of "Solar cells" or "Solar panel", we can trap solar energy in silicon/germanium rods, then we can convert in into electricity too.
Hope this helps!
To solve this problem it is necessary to apply the kinematic equations of linear and angular motion, as well as the given definitions of the period.
Centripetal acceleration can be found through the relationship
Where
v = Tangential Velocity
R = Radius
At the same time linear velocity can be expressed in terms of angular velocity as
Where,
R = Radius
Angular Velocity
PART A) From this point on, we can use the values used for the period given in the exercise because the angular velocity by definition is described as
T = Period
So replacing we have to
Since
Then the radius in meters would be
Then the centripetal acceleration would be
From the result obtained, considering that it is an unimaginably low value of an order of less than it is possible to conclude that it supports the assertion on the inertial reference frame.
cation
anion is negatively charged, so more electrons then protons,
cation is positively charged, so more protons thatn electrons
