The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food).
I think its 60. I think you would subtract 144-84 to get the mass of the vinegar molecule.
Answer:
<em>7.2 N</em>
Explanation:
length of wire L = 240 m
current I = 500 A
field strength B = 3 x 10^-5 T
magnetic force on a current carrying conductor F is given as
F = BILsin∅
The wires are perpendicular with field therefore sin∅ = sin 90° = 1
therefore,
F = BIL = 3 x 10^-5 X 500 X 240 = 3.6 N
<em>If the wire exists between this two transmission lines, then total magnetic force on the wire = 2 x 3.6 = 7.2 N</em>
Answer:
the umbra and penumbra
Explanation:
The two parts of a shadow are the umbra and penumbra.
A shadow is an expression formed when light from a source is cut blocked by an opaque body.
Most shadows are made up of two parts, umbra and penumbra.
- The umbra is the darkest, and the innermost part of a shadow.
- In the penumbra, only a portion of the light source is blocked. It is more of like a partial shadow.
The umbra is directly formed by light which impinges on an opaque body and it completely cut off.
