Answer:

Explanation:
Since the force applied is parallel to the displacement of the car, the work done on the car is simply given by:

where
F = 1210 N is the force applied on the car
d = 201 m is the displacement of the car
Substituting numbers into the equation, we find:

Answer:
The frequency , speed and wavelength of an electromagnetic wave are related by the formula
Speed = frequency x wavelength
frequency = speed / wavelength
substituting the values
frequency = 3 x #10 ^8# m /s / 1 x #10^15# m
= 3 x #10^-7# /s
Answer:
The fourth graph is the answer
Explanation:
We have inequalities


For the first inequality all points at or below the graph of y are solutions, and for the second inequality all the points above the graph of y are the solutions. So, the solution to these inequalities are points that are above the graph of
and below the graph of
. The shaded region in the fourth graph satisfies these conditions.
<em>Looking at other choices, we see that the first two graphs do not even represent the graphs of our inequalities, and the third graph does represent the inequalities but shades the wrong region. </em>
P.S: the graph of the inequality
is dashed because
is "greater than" and not "equal to"
, so this indicates that the values on the line
are not included. And the graph of the inequality
is a solid line because
is "less than or equal to"
, so we are including the values on the line
, and that's why it's solid.
Your correct answer would be B.
Hope this helps!
