Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
Answer:
The right approach will be Option C "Group 12".
Explanation:
- A table that further arranges the chemical components in addition to expanding the electron configuration. Elements possessing identical characteristics are positioned in almost the same section (column or group), although elements in almost the same row become positioned with a similar amount of electron spheres.
- Group 12 components therefore partially replaced (n − 1)d subshells, and therefore aren't metals, technically accurate. However, although much their chemistry seems to be comparable to something like the components throughout the d block which includes establishing themselves.
Some other options in question are not relevant to something like the given scenario. Because then the option here is just the right one.
Answer:
Approximately 8years
Explanation:
1 year is 365 days and since there are 24 × 60 minutes in a day, then there will be 24 × 60 × 365 minutes in a year, which is 525,600 minutes in one year.
Since one year makes 525609minues, then according to the question, in 4.25 x 10^6 minutes (4250000minutes), there will be:
4250000 ÷ 525600
= 8.08
Approximately there will be 8 years in 4.25 x 10^6 minutes
Here, we can use the resolution of vectors to find the component in the y-axis of the distance traveled by Jin. The southern component is given by:
s = dsin(∅), where s is the southern component, d is the distance traveled and ∅ is the angle below east at which it was traveled.
s = 4sin(30)
s = 2 km
