A standing wave on a string that is fixed at both ends has frequency 80.0 Hz. The distance between adjacent antinodes of the sta

Bingel [31]

Answer:

Speed of the wave in the string will be 3.2 m/sec

Explanation:

We have given frequency in the string fixed at both ends is 80 Hz

Distance between adjacent antipodes is 20 cm

We know that distance between two adjacent anti nodes is equal to half of the wavelength

So $\frac{\lambda }{2}=20cm$

$\lambda =40cm$

We have to find the speed of the wave in the string

Speed is equal to $v=\lambda f=0.04\times 80=3.2m/sec$

So speed of the wave in the string will be 3.2 m/sec

The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). If an object’s mas

lina2011 [118]

You just told us that Weight = (mass) x (gravity),
and that mass=10kg and gravity = 9.8 m/s².

All we need to do is write those numbers in place of the letters.

Weight = (10 kg) x (9.8 m/s²) = <em>98 newtons</em>.
