When a small lab cart collide with a large mass then during the collision two bodies will remain in contact and then apply the contact force on each other
This contact force is always equal on two bodies in magnitude and also it is normal or perpendicular to the contact surface.
This will always follow Newton's III law as per which every action has equal and opposite reaction.
So this contact force will not depend on the mass or any other factor but it will remain same on two colliding bodies.
So here the correct answer would be
<em>They both experience the same magnitude of the collision force.
</em>
Answer:
C. the tilt of Earth’s axis as it orbits around the Sun
Explanation:
The hemisphere which is pointed towards the Sun, it is summer in that hemisphere.
The hemisphere which is pointed away from the Sun, it is winter in that hemisphere.
The tilt of the Earth at 23.4° is responsible for the length of a day in the hemisphere.
In the corresponding hemisphere the day is longer in the summer season and the day is longer in the winter season.
Hence, the seasons are caused due to the fact that tilt of Earth’s axis as it orbits around the Sun.
Answer:
A. Hydrogen bonding between water molecules.
Explanation:
Specific heat capacity of water can be defined as the amount of heat a gram of water must lose or absorb in order to change its temperature by a degree Celsius. It is measured in Joules per kilogram per degree Celsius (J/kg°C). Generally, the specific heat capacity of water is 4.182J/kg°C and is the highest among liquids.
Cohesion is a property of water and typically refers to the attraction between molecules of water which holds them together.
The high specific heat and cohesive forces characteristic of water are a result of hydrogen bonding between water molecules. A hydrogen bond is formed in water due to its polarity (opposite charges between water molecules), which causes each water molecule to attract other water molecules. An atom of hydrogen of each water molecule bonds with the electron lone pair on atom of oxygen of a close water molecule.
