Answer:
The excited electron itself can be passed to another molecule
Explanation:
Answer:
Explanation:
given,
vector product
=
now, expanding the vector
the vector product is equal to
Answer: 0.076 m/s
Explanation:
Momentum is conserved:
m v = (m + M) V
(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V
V = 0.076 m/s
After catching the puck, the goalie slides at 0.076 m/s.
To solve this problem it is necessary to apply Newton's second law with the peculiarity that the expression given for velocity must be expressed in terms of the rate of change of velocity and time.
Mathematically this is,
F= ma
Where,
m = mass
= Change in velocity
t = Time
Since the time interval occurs when the speed hits - in the downward direction - until it bounces - in the upward direction - we will have that the change in speed is given by
The rest of our values are given as:
m = 0.26s
t = 0.44kg
Finally replacing we will have to
Therefore the final average force of the floor on the ball is 13.53N
The statement that best predicts a long term effect of the changes in the tilt of the Earth's axis of rotation is : The Earth's climate would change.
The reason lies in the Milankpovitch cycles, accordinh which a greater tilt makes the seasons more extreme.
