The reason a penny thrown straight up inside a bus will come back to your hand is that you, the bus, the air inside the bus, and

the penny are all moving at the same velocity.The law of inertia applies to both moving and nonmoving objects.

Answer:

its false

Explanation:

since the penny is thrown straight up its not going to move forwad with you and the bus since it has no forces pushing on it. If the bus wasn't moving it would land back on your hand

A 1.6 Kg bird that is flying through the air has 220 J of kinetic energy. How fast is the bird flying?
xxTIMURxx [149]

Answer:

v = 16.58 m/s

Explanation:

Given that,

Mass of a bird, m = 1.6 kg

Kinetic energy of the bird, K = 220 J

We need to find the speed of the bird. The formula for the kinetic energy is given by :

E=\dfrac{1}{2}mv^2

Where

v is the speed of the bird

So,

v=\sqrt{\dfrac{2E}{m}}

Put all the values,

v=\sqrt{\dfrac{2\times 220}{1.6}}\\\\v=16.58\ m/s

So, the speed of the bird is equal to 16.58 m/s.

k0ka [10]

Answers:

a) 222.22 m/s

b) 800.00 km/h

Explanation:

The speed of a wave is given by the following equation:

v=f \lambda

Where:

v is the speed

f=\frac{1}{T} is the frequency, which has an inverse relation with the period T=1 h

\lambda=800 km is the wavelength

Solving with the given units:

v=\frac{1}{T}\lambda

v=\frac{1}{1 h}800 km

v=800.00 km/h This is the speed of the wave in km/h

Transforming this speed to m/s:

v=800.00 \frac{km}{h} \frac{1 h}{3600 s} \frac{1000 m}{1 km}

v=222.22 m/s This is the speed of the wave in m/s

Heat likes to remain <br> ONMFRIU ← Whats that unscrambled?
OlgaM077 [116]
<span>So the question is how does heat prefer to remain and to unscramble the letters ONMFRIU. The unscrambled letters mean: UNIFORM. The heat likes to remain uniform because thermodynamic systems always tend to reach thermal equilybrium after some period of time that is specific for each system. </span>
