<u>We are given:</u>
Initial velocity (u) = 32 m/s
Acceleration (a) = 3 m/s²
Displacement (s) = 40 m
Final Velocity (v) = v m/s
<u>Solving for the Final Velocity:</u>
from the third equation of motion:
v² - u² = 2as
<em>replacing the variables</em>
v² - (32)² = 2(3)(40)
v² = 240 + 1024
v² = 1264
v = √1264
v = 35.5 m/s
Therefore, the velocity of the bike after travelling 40 m is 35.5 m/s
Answer
Given,
Sirius A surface temperature,T = 9400 K
Sirius A luminosity,L = 26 L₀
L₀ is the luminosity of sun.
Radius of sun = 695700000 m
Temperature on sun surface = 5780 K
Luminous intensity is given by:-
Now
f = 10000N
distance moved = 20 m
work done = 10000*20 = 200000
They absorb the energy of seismic waves.
Explanation:
Base - isolators, rubber and steel pads under buildings reduces earthquake damage by absorbing the energy of seismic waves.
- Earthquakes are produced by the sudden release of energy within the earth which causes displacement and sharp movement on earth surface.
- There are four main types of waves that are propagated by seismic waves which wrecks havoc.
- Understanding the waves and their properties has been useful in designing earthquake resistant structures.
- Base-isolators, rubber and steel pads helps to absorb seismic waves.
- When seismic waves are absorbed, they are cut off.
- This way they cannot cause damage.
