Answer:
Conservation
Explanation:
She has observation conservation because If the temperature of the liquids stays constant and the container is insulated and not heat or cool the liquid much would not change the density of the liquid very much so that it's original volume could remain constant.
The interesting thing is not that the child assumes the taller glass holds more liquid but that they fail to understand conservation: the fact that the water from one glass is going to be the same amount after being poured into any other container. It's as if they did not realize the water came from the same glass.
I don’t rly get ur question
Using idea of conservation of impulse-momentum theorem, the instantaneous velocity times mass is equal to force times the change in time.
mv = Ft
To reduce the force, decrease the velocity and mass. You can also extend the time of the collision. This is why cars collapse on impact. They were design that way to reduce the force on the car and the passenger.
Hopes this helps!
Answer:
<em>c. decreasing.</em>
Explanation:
Force produces acceleration or deceleration. Force is the product of a body's mass and its acceleration. When a force is applied to an object, the force tends to cause the body to move if the body was originally stagnant, cause the body to accelerate if applied in the direction of the body's velocity, or decelerate the body if applied in opposite direction to the velocity of the body. <em>When the force that is exerted on a moving body is slowly reduced to zero, frictional forces between the body and the floor surface gradually decelerates the body. When this deceleration occurs, the velocity of the body gradually decreases t a stop.</em>
Answer:
The speed of elephant must be 1.4 m/s.
Explanation:
Mass of the elephant, M = 2800 kg
Mass of sprinter, m = 77 kg
Speed of sprinter, v = 8.5 m/s
It is required to find the speed of elephant to have the same kinetic energy as that of sprinter. So,
So, the speed of elephant must be 1.4 m/s.
