elixir [45]3 years ago
8 0

Answer:

a --> true, b --> false, c --> true, d -->false

Explanation:

a) since it stays floating the gravity force and the upqards push is the same

b) if it's balanced the rocket won't move from the ground, the force of the rocket, has to exceed the force of gravity

c) since it's going in a diretion the force of gravity is exceeding the force pushing it up

d) since that are speeding up at a rate, meaning growing, the force is unbalanced.

When you look at yourself in a convex mirror, you appear to be ¼ your actual size. If you are standing 1.0 m in front of the mir
Nookie1986 [14]

Answer:

The focal length is   f  =  -0.2 \  m

The radius of curvature is R = -0.4 \  m

Explanation:

From the question we are told that

       The magnification of the mirror is  m =  \frac{1}{2}

       The distance of the person from the mirror(the object distance ) is  u = - 1.0 \ m

        The negative sign shows that it is been placed in front of the mirror

         

Generally the magnification of the mirror is mathematically represented as

       m  =  \frac{v}{u}

=>   \frac{1}{4}  = \frac{v}{-u}

=>   v  =  \frac{- 1}{4}

Generally from the lens equation we have that

        \frac{1}{f}  = \frac{1}{u}  + \frac{1}{v}

=>     \frac{1}{f}  = \frac{1}{-1 }  + \frac{1}{-\frac{1}{4} }

=>     f  =  -0.2 \  m

Generally the radius of curvature is  mathematically represented as

         R = 2 *  f

=>      R = 2 *   - 0.2

=>      R = -0.4 \  m
