Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave. ... Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
Electrical generator which operates using a magnetic field. It is the beginning of modern dynamos.
Answer:
Pressure at P point is given as
Explanation:
As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe
here we know that
L = 4 cm
r = 1 mm
Q = flow rate
now we have
This question is not about physics science.
The answer is: option <span>a. Five-year-old children have longer attention spans than three-year-old children.
It is the attention ability what let the older children to stay longer in one location instead of being moving between different activities. The younger children who cannot keep their attention long time in a same activity entertain themselves by changing activities.

Answer:
Explanation:
height lost h = 300 sin60
= 259.8 m .
gravitational potential energy = mgh
= 5000 x 9.8 x 259.8
= 1273 x 10⁴ J
Kinetic energy
= 1/2 mv²
= .5 x 5000 x 60²
= 900 x 10⁴ J
there is loss of kinetic energy = 373 x 10⁴ J.
This loss in energy is due to kinetic friction that came into action when the sled slipped downwards.
The lost energy is converted into heat energy or thermal energy.
