Answer:
Power, P = 162.53 Watts
Explanation:
Given that,
Mass, m = 200 g = 0.2 kg
Initial speed of the snake, u = 0
Final speed of the snake, v = 32 m/s
Time, t = 0.63 s
Power of an object is given by :
P = 162.53 Watts
So, the power of the rattlesnake is 162.53 Watts. Hence, this is the required solution.
Answer:
Explanation:
velocity of wave in a tense wire is given by the expression
v is velocity . T is tension and m is mass per unit length .
for steel wire
m = π r² ρ where r is radius and ρ is density
= 3.14 x (5.3 x 10⁻⁴)²x7.75 x 10³
= 683.57 x 10⁻⁵ kg/m
v =
= 1.47 x 10² m /s
= 147 m /s
for iron wire
m = π r² ρ where r is radius and ρ is density
= 3.14 x (5.3 x 10⁻⁴)²x7.86 x 10³
= 693.27 x 10⁻⁵ kg/m
= 146 m /s
Time taken to move from one end to another
= 17.7 / 147 + 28.5 / 146
= .12 + .195
= .315 s .
Generally, the symbol 
is used to indicate the angular velocity.
In a circular motion, the angular velocity is defined as the time rate of change of the angular displacement, relative to the origin. If we call
the angular displacement of an object relative to the origin, and t the time, the angular velocity can be written as
and it is measured in radiants per second (rad/s).
