Acceleration = change in velocity / time
change in velocity = final velocity - initial velocity
because the object is slowing down, the acceleration will be negative.
acceleration = (4-34) / 60
acceleration = -30 / 60
acceleration = -0.5 m/s^2
answer : the train is accelerating at -0.5 m/s^2
Answer:
The steeper the slope, the higher the density
Explanation:
A graph of mass against volume of different substances helps us to know that the slope is density since density is given by mass per unit volume. Therefore, the steeper the slope, the higher the density and vice versa.
If the resistance is ohmic (follows Ohm's law of V=IR), then current should be
I = V/R, where I is current, V is voltage, and R is resistance.
Current in this case will be
I = (120V)/(100Ω)
I = 1.2A
Answer:
The correct answer is 24.
