Answer: This phenomenon happens due to upthrust exerted by water.
Explanation:
We know that,
Liquid Pressure is directly proportional to the height of the vertical column in the liquid.(P∝h)
When a bucket filled water is sunk into the water container, there occur difference in the pressure in top and bottom of the water container. Due to this, water exerts an upward force on the bucket filled with water. This is called Uprthrust.
Upthrust on the bucket makes the bucket filled with water lose some of it's weight and causes apparent loss in weight.
Hence, the bucket filled with water seems light while it sinks into water.

Masa división por volumen igual a densidad
Assuming the cart rests on a perfectly smooth and horizontal surface, then we can apply Newton's second law,
F=ma => a=F/m
Acceleration, a = Force/mass = 16 N / 8 kg = 2 m/s^2
Answer with Explanation:
We are given that
Electric field vector=
Magnetic field vector=
We have to find the direction of propagation of the wave.
We know that
The direction of propagation of wave=
The direction of propagation of wave=
Because (
)
The wave propagate in -z direction.
Therefore, the component of the vector is (0,0,-1).
Hence, the direction of the propagation of wave is - z direction and component of direction of propagation vector is (0,0,-1).
