C. The bowling ball and the bicycle
p = mv
P of bike = 12x5 = 60
P of rock = 2x20 = 40
P of ball = 5 x 10 = 60
No it isn't. energy from the sun travels to us in the form of radiation.
Answer:
a. i. conducting wire
ii high-pass and low-pass filters
iii. Cobra-4 Xpert-link
iii. voltage source
b. Power generated is 3.6 W.
Explanation:
Ohm's law state that the current passing through a metallic conductor, e.g wire is directly proportional to the potential difference across its ends, provided temperature is constant.
i.e V = IR
i. conducting wire
ii high-pass and low-pass filters
iii. Cobra-4 Xpert-link
iii. voltage source
b. Given that; V = 12 V and R = 40 Ohm's.
P = IV
From Ohm's law, I =
So that;
P =
=
=
= 3.6 W
The power is 3.6 W.

Answer:
A composite material can combine the best properties of different materials.
Explanation:
For example, plastic doesn’t look too nice, isn’t easy to clean, and sometimes affects taste. So, combining wood with plastic helps overcome the cons of plastic while keeping the pros of wood. The composite material is lightweight and is hard to break or dent.
