When the wind will be stronger, it will exert more force on particles and hence larger particles erodes
In short, Your Answer would be "True"
Hope this helps!
Answer:
8.36 g
Explanation:
From;
0.693/t1/2 = 2.303/t log (No/N)
t1/2 = half life of potassium-40
t = age of the sample
No= initial amount of the sample
N= amount of the sample at time t
Substituting values;
0.693/1.3 × 10^9 = 2.303/2.6 × 10^9 log (No/2.10)
5.33 × 10^-10 = 8.86 × 10^-10 log (No/2.10)
5.33 × 10^-10/8.86 × 10^-10 = log (No/2.10)
0.6 = log (No/2.10)
Antilog (0.6) = (No/2.10)
No = 2.10 × Antilog (0.6)
No= 8.36 g
Answer:
No
Explanation:
We first find the solubility of the copper sulphate salt
Number of moles= 4.6 moles
Volume =1.75 L
Molarity= number of moles/ volume = 4.6/1.75= 2.6 molL-1
Hence, only 2.6 moles of Copper II sulphate dissolves in 1.75L of water. Hence 4.6 moles of copper II Sulphate dies not dissolve in 1.75 L of water.
Electromagnetic radiation in increasing energy order:-

<h3>Electromagnetic waves</h3>
The energy transfer technique is the use of electromagnetic waves. They are created when a fluctuating magnetic field causes a fluctuating electric field. These induced, perpendicularly oscillating electric and magnetic forces are what make up electromagnetic waves. Electromagnetic waves can travel without a medium, in contrast to mechanical waves. Therefore, even in the absence of a medium, electromagnetic waves can pass through a vacuum. Radio waves, microwaves, infrared waves, visible light, ultraviolet light, X-rays, and gamma rays are all examples of electromagnetic waves
Electromagnetic wave Wavelength
(1) Microwave = 1 mm to 0.1 m
(2) Ultraviolet = 10 nm to 400 nm
(3) Radio waves = 1 mm to 100 km
(4) Infrared = 700 nm to 1 mm
(5) X-ray = 0.01 nm to 10 nm
(6) Visible = 400 nm to 700 nm
