Answer:
The PE of system changed from 17.40 joules to 0 joules
Explanation:
Here m= mass of block = 3.7 kg
g= gravitational acceleration = 9.8 m/sec2
h= Height = 0.48 m
Potential energy at point A
PE= mgh = 3.7 × 9.8 × 0.48= 17.40 j
At point B 0.48 m below on ground
PE = mgh =3.7 × 9.8 × 0 = 0
Answer:
The answer is theory. Hope that's the right answer
Jupiter does. :) it has many storms, causing the wind
Answer:
a) Y component of the vector =15.54 m
b) Vector magnitude = 21.6 m
Explanation:
The given vector makes 44 degree angle with Y axis, as given. This is same as 90 -44 = 46 degrees with the horizontal or X axis.
b) X component of the given vector = = A cos 46 =15
⇒ A = 15/cos 16 = 21.6 m = Total vector magnitude.
a) Y component of the vector = 21.6 sin 46 = 15.54 m
b) A = 21.6 m
No, personal trainers and doctors have very different careers. Though they both do well for the body and health.
