Answer:
No
Explanation:
The Earth lies in one of the outer arms of the Milky Way galaxy. The Milky way that you see is the central portion of the galaxy that is visible. It consists of millions of stars, star clusters, dust and gas. The stars, dust and gas are part of the Milky Way only. It is a dense band. It obscures any outside view beyond the galaxy. Thus, you are not able to see any distant galaxies in the this band.
Answer:
The direction of magnetic field produced by a current carrying wire is given by the right hand thumb rule. If the thumb points in the direction of current the fingers curl along the direction of magnetic field.
further, The red end of the compass needle points in the direction of external magnetic field. As the red end of the needle is pointing away from us, the external magnetic field at its location should also be directed away from us. Using the right hand thumb rule, we can see that this is only possible if the current in the wire is flowing upwards.
Explanation:
Lamarck theory of evolution was based around how organisms (animals, planets) changing during their lifetime , and then pass changes onto their offspring.
darwin theory became acceptable because it had more evidence that supported it.
Explanation:
Equation for Impact
FΔt = ΔP,
F = force
Δt = Impact of time
ΔP = Change in momentum
Car steering is engineered to fail in order to maximize the time of contact and hence reduce the initial impact and mitigate the damage incurred.
Road guard railing crumple on contact to maximize impact time and hence reduce impact intensity and mitigate damage.
Road safety containers are loaded with liquid or sand as they improve the period of impact.
Answer:
Explanation:
Degree of unsaturation can be calculated by the formula
DU = (2C+2+N-X-H)/ 2 where
C is the number of carbons
N is the number of nitrogens
X is the number of halogens (F, Cl, Br, I)
H is the number of hydrogens. Oxygen and sulfur are not included in the formula because saturation is unaffected by these elements
So for C18H29NO2
DU = (36+2+1-29)/ 2 = 05.
The IR at 1735 cm-1 is indicative of a carbonyl type bond and when combined with the 13C NMR signal at 12 ppm and general H NMR is indicative of a (n) ester funtional group.
The HNMR peak at 6.3 ppm and broad signal at 3325 cm-1 in the IR is indicative of a (n) amine that is bonded to sp2 hybridized central atom.
