Answer:
0.71 m
Explanation:
Let the 5 kg is hang at a distance d from the midpoint.
use the concept of moments.
take moments about the mid point.
Anticlockwise moments = clockwise moments
3 x (0.5 - 0.15) = 5 x d
1.05 = 5 d
d = 0.21 m
So, the distance of 5 kg from 0 mark on the stick is 0.5 + 0.21 = 0.71 m
Define
= unit vector due east.
= unit vector due north.
Therefore
Part (a)
Because
, therefore
B² + (-2.5)² = 4²
B² = 9.75
B = 3.1225 km
Answer:
Part (b)
As a positive angle (counterclockwise) measured relative to the southern direction, the direction of
is
Answer: 53°, measured counterclockwise from the south.
Part (c)
If
, then
(-B)²+(-2.5)² = 4²
B² = 16 - 6.25
B = 3.1225 km
Answer:
Part (d)
The direction of
relative to the southern direction is
tan⁻¹ (-3.1225/-2.5) = 51.3°, measured clockwise from south.
Answer: 51.3° measured clockwise from the south.
Answer:
when you switch off an electrical curcuit you tend to create a 'break' in the curcuit,preventing the electric current to flow around the curcuit,this can be caused by a simple switch or 'break'
Explanation:
Displacement is equals to final position minus initial position so final position is 45.6 m and initial position is 0.2 m so 45.6 - .2= 45.4
Mars: 0.38
weight = mass x surface gravity
multiplying your weight on Earth by the number above will give you your weight on the surface of Mars
If you weigh 150 pounds (68 kg.) on Earth, you would weigh 57 lbs. (26 kg.) on Mars
