Answer:
D float.
Explanation:
Here, neutrally buoyant in fresh water
Now,
since the specific gravity of salt water is higher than the specific gravity of the fresh water therefore, the salt water will apply more buoyant force on the object.
And as the object is neutral in fresh water, more buoyant force will make the object float in the salt water.
1
The flow of electrons from negative to positive.
3
Materials that can easily carry electricity from place to place.
4
Materials that do conduct electricity, just not as well as conductors.
5
Materials that stop the flow of electricity.
2
An object that slows down the flow of electric current but still allows some electric current to move, resulting in some of the energy being converted to heat (thermal energy) or light energy in the process.
Answer:
Reflected line
Explanation:
The angle between the reflected ray and the normal ray is called angle of reflection.
Object 2 has more kinetic energy
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion, and it is given by
where
m is the mass of the object
v is its speed
In this problem, for object 1:
m = 2 kg
v = 2 m/s
So its kinetic energy is
For object 2,
m = 4 kg
v = 3 m/s
So its kinetic energy is
Therefore, object 2 has more kinetic energy.
