Answer:
Sulfur
Explanation:
You find the identity by looking at the number of protons. The number of protons never change for an element.
The value of "d" is 80°
Explanation:
Cyclic quadrilaterals are the special group of quadrilaterals with all its base lying on the circumference of the circle. In other words, a quadrilateral inscribed in a circle is called a cyclic quadrilateral.
Cyclic quadrilateral are characterised by some special features such as
- Sum of opposite angles of a cyclic quadrilateral is always a supplementary angle.
- If one of the sides of a cyclic quadrilateral is produced, then the exterior angle so formed is always double of the corresponding interior angle.
Using the property 1
We find that since the quadrilateral is cyclic, opposite pairs must be supplementary
100°
+∠D must be equal to 180°
D=180°
-100°
=80°
Answer:
<h3>25.0 grams is the mass of the steel bar.</h3>
Explanation:
Heat gained by steel bar will be equal to heat lost by the water
Mass of steel= 
Specific heat capacity of steel = 
Initial temperature of the steel = 
Final temperature of the steel = 
Mass of water= 
Specific heat capacity of water=
Initial temperature of the water = 
Final temperature of water =
On substituting all values:
<h3>25.0 grams is the mass of the steel bar.</h3>
Increase in temperature makes the atoms speed up, and decrease in temperature makes the atoms move slower.
Answer:
