There are two tuning forks struck at the same time. One tuning fork is tuned to a frequency note of 500 Hz. The other is tuned t
fomenos

Answer: 26 beats in 2 seconds

Explanation:

The number of beats per second = frequency of tuning fork 1 - frequency of tuning fork 2.

Given :

- frequency of tuning fork 1 = 500Hz

- frequency of tuning fork 2 = 487Hz

Thus,

Beats per second = 500 - 487

= 13 beats per second

Therefore in two(2) seconds, you will have 2 x 13 = 26 seconds.

An object of length 3.00 cm is inside a plastic block with index of refraction 1.40. If the object is viewed from directly above
Lilit [14]
  • The length of its image = -3cm

Given,

length of object, h_o = 3 cm

We know, for flat refracting surface,  

Image distance = object distance

So,

magnification is = -1

length of the image,

h_i = magnification * h_o\\\\h_i = -1 * 3 \\\\h_i = -3cm

Here, negative sign means inverted image.

What is the speed of alpha rays, beta rays and gamma rays ?
Leya [2.2K]
Alpha particles are released by proton rich unstable nuclei. It has no electrons to balance the protons making it positively charged particles moving at very high speeds. Gamma articles are electromagnetic waves of short wavelength and high frequency. It has a speed same as the speed of light. Beta particles are released by neutron rich unstable nuclei. It has a speed of less than the gamma particles.
