Answer:
New speed of the wave, v = 5.77 m/s
Explanation:
It is given that,
Mass of the object, m = 5 kg
Length of the wire, L = 2 m
Speed of the wave, v = 10 m/s
The speed of wave in terms of tension is given by :
If the wire is replaced with one with the same length but three times as heavy, the mass per unit length is given by :
New speed of the wave is given by :
v' = 5.77 m/s
So, the speed of the new wave is 5.77 m/s. Hence, this is the required solution.
Answer:
the answer is b.
=》distance = 10 miles
=》displacement = 0 miles
Explanation:
=》total distance = 2 + 3 + 5 = 10 miles
( sum of total miles covered )
=》total displacement = shortest distance from starting point to the destination. but here both starting point and destination are same so, total displacement = 0 miles
E = mass * specific heat capacity * temperature change
8950 = (174/1000) * 452 * temperature change
temp change = 113.798 degrees
Answer:
B
Explanation:
KE=0.5mv^2
The speed is inversely proportional to the square root of mass
