A man pushes his lawnmower with a velocity of +0.75 m/s relative to the ground. A girl rides by on her bike with a velocity of +
SashulF [63]

Answer:

B. +5.75 m/s

Explanation:

When there are two bodies, a and b, whose velocities measured by a third observer (in this case, the ground) are V_a and V_b respectively, the relative velocity of B with respect to A is given by:

V_{ba}=V_b-V_a

Thus, the velocity of the girl relative to the lawnmower is:

V_{ba}=6.5\frac{m}{s}-0.75\frac{m}{s}\\V_{ba}=5.75\frac{m}{s}

Energy conversion imply the transformation of energy from one form to another. Examples of these conversions in my home include the following:

1. Chemical energy stored in food is converted to mechanical energy used in working(example sweeping)

2. Chemical energy stored in batteries are used to produce sound energy from the radio.

3. Electrical energy flowing through the wires are used to provide heat energy from the heating device.

4. Electric energy stored in the fan is converted to kinetic energy.

5. Chemical energy stored in petrol is converted to mechanical and electrical energies in the generator.

6. Electric energy supplied by the electric gas cooker is used to generate thermal energy after heating water.

7. Electrical energy flowing through the wires supply light energy in the bulbs.

8. Electric energy is converted to light and sound energy in the televisions.

9. Light energy from the sun is converted to chemical energy in the plants at the garden.
