Consider two vectors, A~ = 3.00ˆx + 2.50ˆy and B~ = 1.50ˆx − 2.00ˆy. (a) Calculate the magnitude of each vector. (b) Express the difference B~ − A~ in terms of the Cartesian unit vectors ˆx and ˆy. (c) Find the magnitude and direction of B~ − A~ and express the direction as an angle relative to ˆx. 7. (a) Find the scalar product of the two vectors from the previous problem. Note that the scalar product yields a scalar result (one component). (b) Find the vector product of the two vectors. Note that the vector product yields a vector result (three components). (c) Find the angle between them.

the answer is definitely c.

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.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
