Answer:
I think the answer is Hydro sphere
Explanation:
Earth includes four components
Atmosphere
Biosphere
Hydro sphere
Geosphere
Here Hydro sphere is the goal of question
Explanation:
Electric conductors are the substances which allow easy passage of electric charges from one atom to another in the presence of a certain amount of voltage.
A conductor in which electric charge passes easily is known as a good conductor. Whereas a conductor in which electric charge passes with difficulty or no electric charge passes through is known as bad conductor.
For example, copper is good conductor of heat and electricity as it conducts flow of current quite easily.
Explanation:
the force of attraction towards the centre
of earth or planet is gravity.
for example
- rock in land
- flow of river downwards
- revolution of earth towards the sun
Explanation:
<h2>Radium(Ra)=> </h2>
atomic number=88
<h2>BERYLLIUM (Be)=></h2>
atomic number =4
why is Ra larger than Be
<h3>1. since the atomic number of Ra is greater than Be, the number of electrons is more, which means there are more number of shells present in Ra than Be. </h3><h2>(atomic Radius)</h2>
<h2>2. the more the valence electron (excluding fully filled ones) the less is the nuclear attraction force</h2><h3>since Ra has more valence electron in its outermost shell, the nuclear attraction force is less which means that Ra 's size is greater than Be.</h3>
hope it helps:)
Answer:
75.12 J
Explanation:
Applying,
Q = CΔT................ equation 1
Where Q = amount of heat, C = Heat capacity, ΔT = temperature rise.
From the question,
Given: C = 62.6 J/K, ΔT = 1.20°C
Substitute these values into equation 1
Q = 62.6(1.20)
Q = 75.12 J
Hence the amount of heat it absorbed is 75.12 J
