Answer:
The acceleration of the car is 5m/s²
Explanation:
Given data
Force F= 4,000N
Mass of car m= 800kg
Acceleration a= ?
Applying the Newton's second law of motion which states that the rate of change of momentum of a body is proportional to the external force and takes place in the direction of the force
F=ma
a= F/m
a= 4000/800
a=5m/s²
(360 degrees) / (24hours) = 15 degrees/hour = 1 degree / 4minutes
Answer:
Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
So, in a chemical reaction, the mass before a reaction and after cannot be different. In other words, the mass of the products must be equal to the product of the reactants.
So, this is a <u>true statement.</u>
Answer:
A. A volcano erupts on a small island.
C. Flooding loosens dirt and rocks along a hillside.
Explanation:
Tectonic activities and mass wasting will greatly lead to a change in land forms on earth's surface.
When a volcano erupts on a small island, a change in landform often results. Also, flooding can lead to changes in land form.
- Volcanic eruptions generally adds new materials to the earth surface.
- Magma that reaches the surface called lava deposits rock materials unto the surface.
- During an extensive period of flooding, materials are carried from one place to another and this greatly sculpts the surface of the earth.
