Yes it can cause you put epsom salt in a bath and theirs magnesium in that and it’s good for your body and takes fat from your body
The answer is (1) 24. There are 26 protons in nucleus of Fe atom. There is 26 electrons in Fe atom. Fe atom loses 2 electrons and change to Fe2+ ion. So there is 24 electrons in Fe2+ ion.
Answer:- 4.36 kPa
Solution:- At constant volume, the pressure of the gas is directly proportional to the kelvin temperature.
Where the subscripts 1 and 2 are representing initial and final quantities.
From given data:
= 1.049 kPa
= ?
= 7.39 K
= 30.70 K
For final pressure, the equation could also be rearranged as:
Let's plug in the values in it:
= 4.36 kPa
So, the new pressure of the gas is 4.36 kPa.
Answer:
Option B. is correct
Explanation:
Wind turbines collect the kinetic energy of wind using the turbine blades. The blades turn an electric generator as they are connected to a drive shaft, which in turn produces electricity.
These turbine blades can disrupt flying wildlife including bats and birds.
So,
wind farms can disrupt migrating wildlife.
Option B. is correct.
