Answer:
beat frequency = 13.87 Hz
Explanation:
given data
lengths l = 2.00 m
linear mass density μ = 0.0065 kg/m
String A is under a tension T1 = 120.00 N
String B is under a tension T2 = 130.00 N
n = 10 mode
to find out
beat frequency
solution
we know here that length L is
L = n × 
........1
so λ = 
and velocity is express as
V = 
.................2
so
frequency for string A = f1 = 
f1 = 
f1 = 
and
f2 = 
so
beat frequency is = f2 - f1
put here value
beat frequency = 
- 
beat frequency = 13.87 Hz
It would be hotter near the Earth's equator and colder near Earth's poles.
The purpose of an electrical generator is to convert kinetic energy into electrical energy.
A generator is exactly the thing to use if you need more electrical energy than you have, but at the same time, you have access to something with more kinetic energy than you need.

Astronomers
Explanation:
Astronomy
Field of study
DescriptionAstronomy is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry to try and explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets.

Answer:
Explanation:
Frictional force acting on the box = mg cos 25 x μ where μ is coefficient of friction
= 2.4 x 9.8 x cos 25 x .51 = 10.87 N
Weight of the box acting along the incline = mg sin 25 = 9.94 N
Net force = 10.87 - 9.94 = .93 N . It will create a deceleration of .93 / 2.4
= .3875 m /s² in the box.
v² = u² - 2 a s
v = 0 , a = .3875 , s = 5.4 m
= = u² - 2 x .3875 x 5.4
u = 2.045 m /s
