The direction of a vector multiplied by a scalar is only affected if the scalar is negative, in which case the vector will now be in the opposite direction. If the scalar is positive, the vector will only change in magnitude
Answer:
The velocity of the ball is 5 m/s to the left.
Explanation:
-25kg*m/s divided by 5 kg gives
speed of -5 m/s
The velocity of the ball is 5 m/s to the left.
The AU ... Astronomical Unit ... used to be defined as the average distance between the Sun and Earth during the year.
Now it's defined as 149,597,870,700 meters exactly.

Answer:
93 V
Explanation:
use the expression for induced emf as
EMF = L dI/dt
L = 560 x 10⁻³
dI = 2.5 A
dt = 0.015 s = 15 x 10⁻³ s
EMF = L dI/dt
= 0.560 * 2.5/0.015
= 93.33 V
≅ 93 V
