Evaluate the gravitational potential energy between two 5.00-kg spherical steel balls separated by a center-tocenter distance of

navik [9.2K]

Answer:

U = 8.30×10-⁹J

Explanation:

m1 = m2 = 5.00kg masses of the spheres

d = 15.0cm = 15×10-²m

r = 5.10cm = 5.10×10-²m

R = d + r = 15×10-² + 5.10×10-²

R = 20.10 ×10-²m = 0.201m

G = 6.67×10-¹¹Nm²/kg²

U = Gm1×m2/R = potential energybetween the spheres

U = 6.67×10-¹¹×5.00×5.00/0.201

U = 8.30×10-⁹J

The figure above represents a stick of uniform density that is attached to a pivot at the right end and has equally spaced marks

zavuch27 [327]

Answer:

After 2.0s the angular momentum is $L= 2(4A+3B+2C+D)x$

Explanation:

Let us call forces acting on the rod, A, B, C, and D, and the separation between them $x$ .

Then, the torque due to force A is

$\tau_a = 4Ax$ ,

due to the force B

$\tau_b = 3Bx$ ,

due to force C

$\tau_c = 2Cx$ ,

and the torque due to force D is

$\tau_d = Dx$ .

Therefore, the total torque on the the stick is

$\tau_{tot} =\tau_a+\tau_b+\tau_c+\tau_d$

$\tau_{tot} =4Ax+3Bx+2Cx+Dx$

$\tau_{tot} =x(4A+3B+2C+D)$

Now, this torque causes angular acceleration $\alpha$ according to the equation

$I \alpha = \tau_{tot}$

where $I$ is moment of inertia of the stick and it has the value

$I = \dfrac{1}{3} m(4x)^2$

Therefore the angular acceleration is

$\alpha = \dfrac{\tau_{tot} }{I}$

$\alpha =\dfrac{x(4A+3B+2C+D)}{\dfrac{1}{3}m(4x)^2 }$

$\boxed{\alpha =\dfrac{3(4A+3B+2C+D)}{16mx } .}$

Now, the angular momentum $L$ of the stick is

$L = I\omega$ ,

where $\omega$ is the angular velocity.

Since $\omega = \alpha t$ , we have

$L = \dfrac{1}{3}m (4x)^2 *\dfrac{3(4A+3B+2C+D)}{16mx }* t$

$L= (4A+3B+2C+D)x t$

Therefore, $t = 2.0s$ , the angular momentum is

$\boxed{ L= 2(4A+3B+2C+D)x. }$
