Newton's first law of motion is an object in motion stays in motion until acted upon by another force. Driving at 30 mph in a car is going to stay constant until you crash the car into a wall, stopping the car.
The big bang never occurred. That's all lies. Doctrine...But if you really wanted an answer, its 13.7 billion years ago.
a) The mirror's radius of curvature will be 2.7 cm
B) The magnification of the image will be 4.0.
<h3>What is a concave mirror?</h3>
When a hollow spherical is divided into pieces and the exterior surface of each cut portion is painted, it forms a mirror, with the inner surface reflecting the light.
From the mirror equation;
Hence,
The radius of curvature is twice of the focal length;
Hence, the mirror's radius of curvature will be 2.7 cm.
The magnification factor is found as;
Hence, the magnification of the image will be 4.0.

<span>When sound waves travel from air into water, they'll immediately
start moving faster. (Their speed will increase.)
Of course, this means that although their frequency won't change,
their wavelength will increase.</span>
