What is the sum of the following four vectors in (a) unit-vector notation, and as (b) a magnitude and (c) an angle? Positive angles are counterclockwise from the positive direction of the x axis; negative angles are clockwise. = 4.00 m, at 65.0° = 5.00 m, at -235°

The angle will be "124°". The further explanation is given below.

Explanation:

As we know,

(a)...

Let the resultant of , , and will be , then

⇒  

On putting values, we get

⇒      

⇒      

(b)...

On squaring both sides, we get

⇒  

⇒      

(c)...

Let the resultant angle will be "",

⇒  

⇒  

⇒  

need to see circuit to get time constant

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
