Any vector can be written as components along positive X and positive Y axes.
So vector B can be written as , where is the angle between vector and positive X axis
So vector B =
So components of vector B along X -axis =-6.74 m
along Y-axis = 16.69 m
Answer:
<h2>
<em><u>A) Different parts of the moon throughout the month</u></em></h2>
Explanation:
Every thing I researched on the moon never says you can see all sides of the moon while its spinning expect the full moon. Your gonna see different sides of the moon because it is spinning not staying still. The last one is wrong because the moon goes threw a cycle. (sorry if anything is wrong this is just what I've been learning and understanding about the moon)
The distance between the two masses is d = 1.35 m
The force between the masses is
Let the mass of object 1 be m.
Let the mass of object 2 be 2m.
The formula of force can be written as
Here, the universal gravitational constant is
The mass can be calculated as
The mass of object 2 is
The mass of the first object is 8.45 kg.
The mass of the second object is 16.9 kg.
Answer:
The radius of the loop is 20.66 km
Explanation:
let the radius of the loop be r
mass of airplane is m
At the top, the pilot experiences two radial forces, which are
1) Gravitational force is mg
2) Centrifugal forces mv²/r out of the center
When the pilot experiences no weight,
then, mg = mv²/r
r = v² / g
= 450² / 9.8
= 20.66 x 10³3
= 20.66 km
