Answer:
Explanation:
Gauss' Law should be applied to find the E-field 3.9 cm from the surface of the sphere.
In order to apply Gauss' Law, an imaginary spherical shell (Gaussian surface) should be placed around the original sphere. The exact position of the shell must be 3.9 cm from the surface of the original sphere.
Gauss' Law states that
Here, the integral in the left-hand side is equal to the area of the imaginary surface. After all, the reason behind choosing the imaginary surface a spherical shell is to avoid this integral. The enclosed charge in the right-hand side is equal to the charge of the sphere, -84.0 nC. The radius of the imaginary surface must be 5 + 3.9 = 8.9 cm.
So,
Answer:
When the velocity doesn't change its direction
Explanation:
Since velocity vector has 2 components: direction and magnitude, and speed is the velocity's magnitude. So if the velocity doesn't change its direction, we essentially use its magnitude, aka speed, to calculate the rate of change for acceleration.
Answer:
compression ratio is 7 : 1
Explanation:
given data
volume v1 = 70 cubic inches
volume v2 = 10 cubic inches
to find out
compression ratio
solution
we know that here compression ratio formula that is
compression ratio = ...................1
put here value maximum = 70 and minimum is 10
so
compression ratio =
compression ratio =
so compression ratio is 7 : 1
Answer:
Explanation:
slit separation d = .17 x 10⁻³ m.
Screen distance D = 5.35 m
angular separation of fringe = λ /d ; λ is wavelength.
Given angular separation in radian
180° = π radian
.19° =
=.0033 radian
.0033 =
λ = .0033 x d
= .0033 x .17 x 10⁻³
= 561 x 10⁻⁹
= 561 nm.
