Answer:
Weather is the conditions (temperature, wind etc.) at a given time, like on that day. Climate, which is what his data would show, is the conditions over an extended period of time like the 3 months he collected data
The answer is cardiovascular.
Solution :
Let kg
m/s
Let and are the speeds of the disk and after the collision.
So applying conservation of momentum in the y-direction,
Therefore, the disk 2 have greater velocity and hence more kinetic energy after the collision.
Now applying conservation of momentum in the x-direction,
m/s
So,
= 4.33 m/s
Therefore, speed of the disk 2 after collision is 4.33 m/s
Answer:
is the initial velocity of tossing the apple.
the apple should be tossed after
Explanation:
Given:
- velocity of arrow in projectile,
- angle of projectile from the horizontal,
- distance of the point of tossing up of an apple,
<u>Now the horizontal component of velocity:</u>
<u>The vertical component of the velocity:</u>
<u>Time taken by the projectile to travel the distance of 30 m:</u>
<u>Vertical position of the projectile at this time:</u>
<u>Now this height should be the maximum height of the tossed apple where its velocity becomes zero.</u>
is the initial velocity of tossing the apple.
<u>Time taken to reach this height:</u>
<u>We observe that </u><u> hence the time after the launch of the projectile after which the apple should be tossed is:</u>
Answer:
Explanation:
We define our values according to the text,
R= Radius
Velocity
Strenght of the vortex filament
From this and in a vectorial way we express an elemental lenght of this filmaent as . So,
Where imply a vector acting perpendicular to both vectors.
Applying Biot-Savart law, we have,
Substituting the preoviusly equation obtained,
So we can express the velocity induced is,
