Answer:

25.3m/s

Explanation:

F=ma

F is 4500, M is 1400kg, A is ?

4500=1400×a

a=4500/1400

a=3.2m/s²

then equation of motion

V²=U²+2as

V=?,U=0, a=3.2,s=100m

V²=0+2×3.2×100

V²=640

  • square both side

V=√640

V= 25.3m/s

Drupady [299]
<h2>Answer:</h2>

<u>A forest ranger might be ranked as being high in </u><u>Naturalistic</u><u> intelligence.</u>

<h2>Explanation:</h2>

Naturalistic intelligence is the type of intelligence that relates the activities of people that how sensitive an individual is to nature and the world. Zookeepers, biologists, gardeners, and veterinarians are among those people who have a higher capability of having high naturalist intelligence.

A dentist uses a concave mirror to examine a tooth that is 1cm in front of the mirror. The image of the tooth forms 10cm behind
iragen [17]

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;

\frac{1}{p}+\frac{1}{q}  =\frac{1}{f} \\\\ \frac{1}{1}+\frac{1}{-10}  =\frac{1}{f} \\\\ \frac{1}{f} = 1-\frac{1}{10} \\\\  \frac{1}{f} = \frac{9}{10} \\\\ f= 1.1111

Hence,

The radius of curvature is twice of the focal length;

\rm R = 2f \\\\ \rm R = 2\times 1.111 \\\\ R=2.2222 \  cm

Hence, the mirror's radius of curvature will be 2.7 cm.

The magnification factor is found as;

\rm  m = \frac{-q}{p} \\\\ m = \frac{-(-10)}{1} \\\\ m = 10

Hence, the magnification of the image will be 4.0.
