The distance is the total distance she walked which is 16 meters adding the 6 meters to the corner and 10 meters to her friend's apartment. Her displacement is the distance from her original starting point so you set up a triangle with side lengths of 6 and 10 and solve for the hypotenuse which gives you a displacement of 11.66 meters.
The answer is 3. Internal energy decrease
Answer:
= 591.45 T/s
Explanation:
i = induced current in the loop = 0.367 A
R = Resistance of the loop = 117 Ω
E = Induced voltage
Induced voltage is given as
E = i R
E = (0.367) (117)
E = 42.939 volts
= rate of change of magnetic field
A = area of loop = 7.26 x 10⁻² m²
Induced emf is given as
= 591.45 T/s
Answer:
The black cow takes in more of the sun than the white cow does. It absorbs the heat faster.
Explanation:
Answer:
Vf = 5.05 m/s
Explanation:
To know this, you need to use the expressions for free fall.
In this case, we only know the length of the stick which is 1.3 m.
The stick is held vertically and then is allowed to fall freely. Now, we want to know the final speed of the stick when it reach the floor.
In this case, we can assume that when the stick is allowed to fall, the innitial speed is 0. Then, the other thing we can assume is the height where the stick is put to fall. In this case, the height is the same as the length, because the stick is already on the floor but is standing vertically.
So, we have here the height, and if the stick is falling, is because of gravity, which is 9.8 m/s²
To calculate the speed, you can use this expression:
Vf = √2*g*h
Replacing the data we have:
Vf = √2 * 9.8 * 1.3
Vf = 5.05 m/s
