To solve this problem we will apply the concepts related to the linear kinematic movement. We will start by finding the speed of the body from time and the acceleration given.
Through the position equations we will calculate the distance traveled.
Finally, using this same position relationship and considering the previously found speed, we can determine the time to reach your goal.
For time (t) and acceleration (a) we have to,
The velocity would be,
Now the position is,
Now with the initial speed and position found we will have the time is,
Solving the polynomian we have,
Therefore the rocket will take to hit the ground around to 4.56min
Answer:
Electron is negatively charged because you don't get work or in simple words charge out of it.
Explanation:
Answer:
F = M a = M v^2 / R
If v is increased by three the force will be increased by nine,
C) is correct
Answer:
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Explanation:
Answer:
Since the force between wires is attraction type of force so current must be flowing in upward direction
Explanation:
Force per unit length between two current carrying wires is given by the formula
here we know that
now we will have
Since the force between wires is attraction type of force so current must be flowing in upward direction
