When the bus starts moving forward, the man remains at rest,
causing him to lean back.
When the bus slows down, the man continues to move forward,
and appears to lean forward.
Both events are examples of the effect of inertia.
A homogenous mixture is a mixture that is uniform throughout and can be
separated by physical means. An example of which is the blood where its
composition is uniformly mixed throughout but it can be separated by
centrifugation, a physical means using the speed of rotation. Here, the denser
particles are forced to settle in the bottom and the lighter particles stay at
the top when rotated quickly.
I think it would be clean and store.
Answer:
f = c / λ
Explanation:
Electromagnetic waves are types of periodic waves. They propagate with the same speed as light (3 * 10⁸ m/sec).
Therefore:
velocity of wave = c
Now, the equation that relates speed of wave and its frequency is as follows:
c = λf
where:
c is the speed of wave
f is the frequency of the wave
λ is the wavelength of the wave
Solve the above equation for frequency, we will end up with:
f = c / λ
Answer:
14cm
Explanation:
Mass per gram of the piece of wire;
2g of the wire is found in 1m
Since
100cm = 1m;
So;
100cm of the wire contains 2g of the wire
To provide 0.28g
Since;
2g of wire is made up of 100cm
0.28g of wire will be contained in 
= 14cm
14cm of the wire will contain 0.28g
