Answer:
The amplitude of the sound wave will increase.
Explanation:
Answer:
The acceleration of Chevy Corvette is 
.
Explanation:
Given that,
Initial speed of Chevy Corvette Z06, u = 0 (it starts from rest)
Final speed of Chevy Corvette Z06, v = 60 mph
1 mph = 0.44704 m/s
60 mph = 26.82 m/s
Time, t = 3 seconds
We need to find the acceleration of Chevy Corvette. The rate of change of velocity is called acceleration of an object. It is given by :
So, the acceleration of Chevy Corvette is . Hence, this is the required solution.
Answer:
average force is 138900 N
Explanation:
given data
speed = 50 km/h = 13.89 m/s
mass = 1500 kg
time = 0.15 s
to find out
average force
solution
we know initial velocity of car is positive
we will apply here equation to find force that is
Force x change in time that is equal to mass x change in speed ................1
so put here all value of mass, time and velocity in equation 1
Force x 0.15 = 1500 x ( -13.89)
force = 138900 N
so average force is 138900 N
(a) the principle of aerodynamic convergence
(b) the centripetal force
(c) Conservation of angular momentum
(d) Conservation of kinetic energy
(e) None of these
Conservation of angular momentum
Answer: Option C.
<u>Explanation:</u>
The law of conservation of angular momentum expresses that when no outer torque follows up on an article, no difference in precise force will happen.
The law of conservation of angular momentum expresses that the angular energy of a body that is the result of its snapshot of latency about the hub of revolution and its rakish speed about a similar pivot, can't change except if an outside torque follows up on the framework.
