Explanation:
Advantages of physical models include accuracy, safety, visualization, education, and trying things out that would be impossible in the real world due to safety, cost, or practical concerns. You can visualize things that are extremely tiny, happened millions of years ago, or that otherwise can't be viewed directly.
Explanation:
It is given that,
The position of a particle is given by :
(a) Velocity of a particle is given by :
Putting values,
The acceleration of the particle is given by :
(b) At t = 0,
Velocity, v = 6k m/s
Acceleration, a = 6i m/s²
Answer:
375 km
Explanation:
Using the equation, d = vt, we simply plug in the numbers:
v = 150 km/hr
t = 2.5 h
d = (150 km/hr)*(2.5 h)
d = 375 km
Answer:D) The kinetic energy decreases and the gravitational potential energy increases
Explanation:
option D
you compare the data from your experimental results to the prediction being tested
