Function of insulators is protection against sound or electric current or ,heat based on the type of insulators.
They use in wires (plastic)
Use in making soundproof rooms
Thermal insulators are use in making water bottles. Keep the water warm
Answer:
v = 13.79 m/s
Explanation:
given,
mass of ball = 110 g
height = 11 m
ball is released from = 1.3 m
minimum speed = ?
using conservation of energy
Potential energy is conserved in the form of kinetic energy
v = 13.79 m/s
Answer: Scientists believe the missing carbon has found a sink in the Northern Forest. Scientist have come up with this idea because they believe consequences of global warming contributed to significant extent to the northern forest carbon sinking processes. In addition to that, scientists describe a process where the oceans of the world sink carbon to create a balance of the ecosystem. That is why they are not 100% sure.
Explanation:
Answer:
Explanation:
Y = 5 Sin27( .2x-3t)
= 5 Sin(5.4x - 81 t )
Amplitude = 5 m
Angular frequency ω = 81
frequency = ω / 2π
= 81 / (2 x 3.14 )
=12.89
Wave length λ = 2π / k ,
k = 5.4
λ = 2π / 5.4
= 1.163 m
Phase velocity =ω / k
= 81 / 5.4
15 m / s.
The wave is travelling in + ve x - direction.
