Answer:
A, B, and E
Explanation:
C and D are wrong;
Line graphs do not show the dependent variable on the x-axis.
Line graphs do have both an x-axis and a y-axis.
Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as
so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
After 9 years of spectacular findings, NASA shut down the Kepler space telescope at the end of last October (2018).
From 2009 to 2018, the Kepler mission found more than <em>2,600</em> planets in other "solar systems" ... in orbit around other stars besides our Sun. AND, at the time the mission ended, (5 months before the night I'm writing this), there were still more than 2,000 sets of data still to be analyzed.
The results suggest that having a family of planets is really not an unusual thing for a star. Indeed, the rare, unusual stars may be the few that don't have planets orbiting them.
Planets around other stars are probably so common that they are the rule, and not the exception to the rule.
Explanation:
the density of liquid x is 40g and a bottle full of water has the density of 70g find the density of liquid x (d=1g/cm3)
Answer:
The least possible volume is
Explanation:
We are asked by the least volume to store 1 mJ at 2000 V.
So, we can use the given formula for and solve for Vol.
replacing the values given in the problem and the permittivity of space which is we obtain Vol.
Note that in the above solution
Additional:
Taking into account that the volume of dieletric will be the area of plates (A) times the separation between plates (d).
You also can calculate A and d
d is calculated assuming that the is 2000 V and using given equation for :
and A is calculated dividing Vol by d
