the answer is not D ....... the answer is {B} if you got it right give me a 5 stars and a hard
Environmental science enlightens us on how to conserve our environment in the face of increasing human population growth and anthropogenic activities that degrade natural resources and ecosystems.
Explanation:
The scope of environmental studies is very wide and it deals with many areas like:
(i) Conservation of natural resources,
(ii) ecological aspects,
(iii) pollution of the surrounding natural resources,
(iv) controlling the pollution,
(v) social issues connected to it, and
(vi) impacts of human population on the environment.
Rare, noble or inert gasses have complete outer shells.
He-Helium, Ne-Neon, Ar-Argon, Kr-Krypton, Rn-Radon, Xe-Xenon
When two sphere will have maximum force then the charge will be equally divided among them
so here we can say
here for maximum force
now we have
now we have to find the charge transferred so that force is 1/4 times the maximum force
here in above equation q1 is charge that is transferred
now by solving above equation we have
so we will have
Answer:
FT = 103.15 N and T = 1.75 s
Explanation:
There are 3 forces at play here: gravity acting in vertical direction, tension from the string that makes 18 degrees with the vertical, and centripetal force generated by the circular motion which is horizontal.
Since the bob is moving at the constant speed, according to Newton 's 1st law the net force is 0. To find the tension force that makes a fixed angle of 18 degrees with the vertical, we can calculate that tension in the vertical direction and balance it with gravity force. Let g = 9.81m/s2
To calculate the centripetal force in the horizontal direction, we can calculate tension in the horizontal direction and balance it with the centripetal force
The centripetal acceleration a is
The radius of circular motion is:
The angular speed is
The time it would take to sweep 1 period, or 2π rad is
