Answer:
We can think that the girl is initial over the skateboard, when she jumps forward, most of the force that she applies is downwards, so the force is transmitted from the skateboard to the ground.
Now, as she jumps forward, there is also some force applied in the horizontal direction, this force will affect the skateboard, accelerating it in the opposite direction (backward).
As the skateboard is way less heavy than the girl, the acceleration that the skateboard experiences will be bigger. Now, we can not estimate how much the skateboard moves, because we do not know the initial velocity of the skateboard.
Answer: i think its c but i am not sure tho but i think its she could replace the 6 v battery with a 12 v battery
Explanation: cause a 12 v is stronger than a 6 v battery
To solve this problem we will apply the concepts related to dynamic equilibrium. The vertical component of the tension is equivalent to the centripetal Force while the horizontal component of the tension is equivalent to the weight, therefore we will have the two equations,
Our values are,
Therefore if we divide both equation we have,
Replacing,
Therefore the angle required is 15.18°
Answer: Bob's private key
Explanation:
Since Bob is sending Alice the message, it simply implies he must have encrypted it with his key that Alice can be able to use to decrypt the message.
Answer:
a circuit that is a blend of series paths and parallel paths. See Figure for a visual explanation. Most circuits are of this variety. Don't be afraid to tackle these circuits as far as the math goes.
