Answer:
Explanation:
current I = 14 x 10⁻³ A
distance of current d = 2.2 x 10⁻² m
Magnetic field B due to a long straight current carrying wire
B = (μ₀ /4π) x (2 I / d )
= 10⁻⁷ x 2 x 14 x 10⁻³ / 2.2 x 10⁻²
= 12.72 x 10⁻⁸ T .
Think Critically: Suppose a car is accelerating so that its speed is increasing. Describe the plotted line of the motion of the car on a distance-time graph. The plot would be a curved line sloping upward whose slope is increasing.
Answer:
The question is incomplete however this kind of questions about determinate the angular speed and taking a reference of days rotating the first star.
w=0.11312 rad/s
Explanation:
The situation is about a two star the question is incomplete, miss the time rotate one star so we assume the first star rotated once in 30 days so:
Angular momentum
The inertia
The momentum must be conserved so
notice don't have to know the mass or use the density however at the end can determinate
Time can determinate the frequency so determinate angular speed of the first star
Circular acceleration has 2 components, the centripetal and tangential acceleration.
The formula for calculating the centripetal acceleration of a particle
is:
= v^2/r
Where v is the velocity or instantaneous speed and r is the radius.
= (3^2)/6 = 1.5 m/s^2
Assuming that the particle stays on the same circular path, another
thing it can have is the tangential acceleration. While the centripetal
acceleration is constant, tangential acceleration depends on the location of
the particle in the circular path. So to answer A and B, yes we can have an
acceleration of 6 and 4 respectively.
