Why do some objects bounce when you throw them at a wall?
Wewaii [24]

Answer:

When you throw a ball against a wall or drop it onto the floor, you notice that it bounces back up again. In the same way, when the ball hits the floor and gets squished, it pushes back against the floor to try to make itself round again.

A 0.0600-kilogram ball traveling at 60.0 meters per second hits a concrete wall. What speed must a 0.0100-kilogram bullet have i
GarryVolchara [31]

Answer:

the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s

Explanation:

The computation of the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is as follows:

The ball momentum is

\Delta Q = mv\\\\\Delta Q = 6 \times 1^-2 \times 60\\\\\Delta Q = 3.6 kg \times m/s

As there is a similar momentum

So,

\Delta Q = MV\\\\3.6 = 10^-2V\\\\V = 360 m/s

Hence, the speed that have 0.0100 kilogram bullet with the similar momentum magnitude is 360 m/s

A 10.0 m wire is hung from a high ceiling and held tightly below
yan [13]

Answer:

5 m

Explanation:

Speed of waves is as the product of frequency and wavelength hence expressed as s=fw where f is the frequency of waves in Hz, s is the speed in m/s and w is wavelength in meters.

Making w the subject of the formula then

w=\frac {s}{f}

Substituting 335 m/s for s and 67 Hz for f then the wavelength is

w=\frac {335}{67}=5m

Wavelength is the distance between successive crests. Since the string is 10m, wavelengths of 5m each will be 2 and the crests will be 3.
