Explanation:
Given that,
Force, 
Position of the particle, 
(a) The toque on a particle about the origin is given by :
Taking the cross product of above two vectors, we get the value of torque as :
(b) Let 
is the angle between r and F. The angle between two vectors is given by :
The moon's gravity, combined with the waltz of Earth and the moon around their center of mass, forces the oceans into an oval shape, with two simultaneous high tides. ... If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it.
A=pi r^2
A=( 3.14159.......)(12.77)^2
A= 512.30m^2
The correct answer would be the first option. Based on the given description above, the type of radiation that is being emitted is ALPHA RADIATION. Alpha radiation is the type of radiation having the lowest penetrative power. Take note that <span>Gamma is stronger than Beta is stronger than Alpha. Hope this answer helps. Have a great day!</span>
Solve for "x"
X = speed of the 5 kg
3/15=5/x
cross multiply
3x=75
because (15)(5)=(3)(x)
divide 3 in both side
X=25
or
A=25 m/s^2
Hope this helps
