Answer:hypothesis: the plant died of lack of light,moisture,or water
Explanation:
to test my hypothesis i put a plant in a room at room temp and repeat how i grew it,and observe what went wrong. hope this helps=)
so what do we want our website for the best of all I can get to see
Its a solid in room temperaturw
Answer: An AU equals the distance between Earth and the Sun; a parsec
equals the angle between an object's apparent positions when viewed
from two different locations.
Explanation:
Light year is the distance light travels in one Earth year. 1 light year is equal to .
An astronomical unit (AU) is the average distance between the earth and the sun. An AU is approximately 150 million km.
A parsec is the distance at which one astronomical unit subtends an angle of one second of arc. 1 parsec is equal to 20600 AU.
Answer:
= -12 N
, = -80 N and = - 44 N
Explanation:
The force is related to the potential energy by the formula
F = -Δ U = - ( i ^ + j ^ + k ^)
It indicates the potential energy
U = 2xyz + 3z² + 4yx + 16
To solve this problem let's make the derivatives, to find each component of the force
= 2yz + 0 + 4y + 0 = 2yz + 4y
= 2xz + 0 + 4x + 0 = 2xz + 4x
= 2xy + 3 2z + 0 +0 = 2xy + 6z
We look for the expression for the force in each axis
= - 2yz - 4y
= -2xz -4x
= -2xy -6z
We calculate at the point P = (20 i ^ + 1j ^ + 4 k ^) m
= - 2 1 4 - 4 1
= -12 N
= - 2 20 4 - 4 20
= -80 N
= - 20 1 - 6 4
= - 44 N
We put together the expression for strength
F = (-12 i ^ - 80j ^ -44k ^) N
