Answer:
v = 315 m/s
Explanation:
given,
length of the string = 64.3 cm
frequency at fundamental mode = 245 Hz
speed of sound = 345 m/s
speed of the transverse waves = ?
here
wavelength = twice length of string
λ = 2 L
λ = 2 × 64.3
λ = 128.6 cm = 1.286 m
using formula
v = ν λ
v = 245 × 1.286
v = 315.07 m/s
Hence, the speed of the transverse wave on the string will be equal to v = 315 m/s
0.2 Hz = v / (0.03 m)

You can use apple cider vinegar. If you don't have it, you can go to shoppers drug mart and they will have an ointment to sooth itches.
<h2>Answer:</h2>
All the energy sources are correctly matched with their category.
Explanation:
Renewable energy sources:
These are energy sources which can be replenished as they don't in involves the irreversible phase change.
These resources can never be ended as they can be used again and again.
Wind, geothermal, biomass, bio gas are example of renewable energy sources.
Non renewable energy sources:
These are the energy source which can never be replenished after one time use. They undergo the chemical irreversible change.
These sources are lacking with the passage of time because they can never be reused.
Oil, gas, coal and natural gas are examples.
There are two forces acting on a parachute with a parachutist: the force of gravity and the air resistance. The force pulling the skydiver to the ground would be Wright force
