When calcium oxide reacts with water, then it combines with water and forms calcium hydroxide.
CaO + H2O → Ca(OH)2
Calcium oxide + Water → Calcium hydroxide
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base

Answer:
Answer (D) d = m/V
Explanation:
density = mass / volume volume = mass / density length x width x thickness (height) = volume >>>substituting>>> length x width x thickness = mass / density thickness = mass / (density x width x length)
1 gram is greater. 230 miligrams is equal to .230 grams
<u>Answer:</u>
For 1: The correct option is Option C.
For 3: The final velocity of the opponent is 1m/s
<u>Explanation: </u>
During collision, the energy and momentum remains conserved. The equation for the conservation of momentum follows:
...(1)
where,
are the mass, initial velocity and final velocity of first object
are the mass, initial velocity and final velocity of second object
<u>For 1:</u>
We are Given:
Putting values in equation 1, we get:
Hence, the correct answer is Option C.
Impulse is defined as the product of force applied on an object and time taken by the object.
Mathematically,
where,
F = force applied on the object
t = time taken
J = impulse on that object
Impulse depends only on the force and time taken by the object and not dependent on the surface which is stopping the object.
Hence, the impulse remains the same.
Let the speed in right direction be positive and left direction be negative.
We are Given:
Putting values in equation 1, we get:
Hence, the final velocity of the opponent is 1m/s and has moved backwards to its direction of the initial velocity.
Answer:
For starters, “dark side” is a misnomer. The far side may be constantly facing away from Earth, but as it orbits the Earth it sometimes faces the sun just as the bright side does. Thus the far side is subject to the same day/night temperature extremes as the side facing Earth.
