Answer:
the object has negative acceleration and eventually
The correct answer is
<span>nuclear weak force
</span><span>
In fact, the nuclear strong force has a very limited range of action (approximately below 1-2 femtometers), and its magnitude decays exponentially for larger distances. Only the nuclear weak force is weaker than the nuclear strong force at large distance, while the gravity and the electromagnetic force become dominant for distances > 2 femtometers.</span>
<span>The atoms are grouped thus forming molecules. Each type of molecule is the combination of a certain number of atoms linked between them and in a specific way, whenever a molecule can contain atoms of different elements or of the same. And that in turn, Each atom retains its structural characteristics, beyond that they are part of different molecules because during the chemical reactions the atoms cannot be created or destroyed, but they are organized in a different way creating links between an atom and another.</span>
Answer:
a).
b).
rpm
c).v=0.5865 m/sec.
Explanation:
Given:
a).
The angular speed in radians per seconds is
b).
rpm
c)
Child's distance per revolution
(pi*2r) = 43.988 metres.
v=(43.988 x 0.0133333) = 0.5865 m/sec.
Explanation:
It is given that,
Speed of the baseball, u = 44 m/s
Speed of the baseball, v = 53 m/s
Mass of the ball, m = 145 g = 0.145 kg
Time of contact between the ball and the bat, t = 2.2 ms = 0.0022 s
F₁ = 2900 N...........(1)
F₂ = 3493.18 N.........(2)
In average vector form force is given by :
Hence, this is the required solution.
