When a car maintains a velocity of exactly 65 mph, it's acceleration is zero.
<h3>What is acceleration?</h3>
The acceleration is time rate of change of velocity.
When the velocity is not changing with respect to time, it is said to be an object moving with constant velocity.
At constant velocity, there is no acceleration.
Thus, when a car maintains a velocity of exactly 65 mph, it's acceleration is zero.

The critical difference is the fact that all four sides of a rhombus have
the same length.
There are several other distinguishing characteristics, but if you make the
lengths of all the sides equal, then the other things happen automatically.
Answer:
5 N
Explanation:
The work done by a force on an object is (assuming that the direction of the force is parallel to the displacement of the object):
where
F is the magnitude of the force
d is the displacement of the object
In this problem, we know that:
W = 35 J is the work done
d = 7 m is the displacement of the object
Therefore, we can re-arrange the equation to calculate the force applied:
Answer:
I believe it is the circulatory system.
Explanation:
Have a nice day.
Radius of curvature, r = 2f
24 cm = 2f
2f = 24
f = 24/2 = 12
Hence the focal length is = 12 cm.
Object distance, u = 4 cm.
Since the object is placed between the focus and the pole of the mirror, at this position for a concave mirror, the resulting image would be virtual and would be behind the mirror.
1/u - 1/v = 1/f
1/4 - 1/v = 1/12
1/4 - 1/12 = 1/v
1/v = 1/4 - 1/12 = (3 - 1)/12 = 2/12 = 1/6
1/v = 1/6
v = 6
Therefore the image is 6cm behind the mirror.
Magnification = v/u = 6/4 = 3/2 = 1.5
Yes, the image is magnified by 1.5 times.
Simply copy the diagram for an object placed between the focus and the pole of a mirror from your textbook.
