Answer:
C. The amount of force applied to rock one was half the amount of force applied to rock two during the eruption.
Explanation:
A force is an agent which changes the state of an object well applied to it. Second Newton's law of motion state's that;
F = ma
where F is the force, m is the mass of the object and a is the acceleration of the object.
In the given question,
Mass of first rock = 10 kilograms
Mass of the second rock = 20 kilograms
Acceleration of the two rocks = 600 m/
Thus,
Force on the first rock = ma
= 10 x 600
= 6000 N
Force on the second rock = 20 x 600
= 12000 N
Therefore, it can be observed that the amount of force applied to rock one was half the amount of force applied to rock two during the eruption.
Answer:
Explanation:
Matter occurs in four states: solids, liquids, gases, and plasma.
States of matter are generally described on the basis of qualities that can be seen or felt.
A solid has a definite shape and volume because the molecules that make up the solid are packed closely together and move slowly.
Answer:
1.The calorie was originally defined as the amount of heat required at a pressure of 1 standard atmosphere to raise the temperature of 1 gram of water 1° Celsius. Since 1925 this calorie has been defined in terms of the joule, the definition since 1948 being that one calorie is equal to approximately 4.2 joules.
2.Boiling water at 100 degrees Celsius: 540 calories are needed to turn 1 gram (at 100 degrees Celsius) of water to steam.
