Answer:
The rate of reaction A is higher.
answer is AAAAA !
Explanation:
Answer:
Explanation:
Features. A tornado is a swirling vortex or column of air with a hollow core. The circulating air often contains debris and dust and moves in an upward spiral at high speeds. The bottom of the tornado column makes contact with the ground, while the top of the tornado can extend 5 or more miles into the sky.
Answer:
19.29 m/s
Explanation:
Apply the conservation of linear momentum in north-south direction:
Apply the conservation of linear momentum in east-west direction:
Dividing the two equations:
Thus, the speed of the eagle immediately after it catches its prey is 19.29 m/s.
Work done = 1/2*(max. force - min. force) * greatest extenstion
Max. force = spring constant * greatest extension= 80*d = 80d N
Min. force = spring constant * smallest extenstion = 80*0 = 0 N
Therefore,
Work done = 1/2*80d*d = 40d^2 J
However,
Mechanical energy = Work done
That is,
0.12 = 40d^2
d = Sqrt (0.12/40) = 0.0548 m
The greatest extension from its equilibrium is 0.0548 m.
To find the kinetic energy KE=1/2 × mass × velocity ^2
for object 1 ke= 1/2(2)(2^2)=4 J
for object 2 ke= 1/2(4)(3^2)=18J
meaning object 2 as more kinetic energy.
