Explanation:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Answer:
-64.0 m/s²
Explanation:
v = 32.0 t − 2.00 t³
Acceleration is the derivative of velocity.
a = dv/dt
a = 32.0 − 6.00 t²
At maximum displacement, v = 0 and a < 0.
v = 0
32.0 t − 2.00 t³ = 0
2.00 t (16.0 − t²) = 0
t = 0 or 4.00
When t = 0 s, a = 32.0 m/s².
When t = 4.00 s, a = -64.0 m/s².
The maximum displacement is at t = 4.00 s. Therefore, the acceleration at that moment is -64.0 m/s².
<span>The answer is transformer. They utilize
electromagnetic induction to generate current. This is only possible in
alternating current due to the differential increase and decrease of electrical
current that induces changes in magnetic flux in the coil. This varies the
magnetic flux of the primary coil that generates current in the secondary coil.</span>
No they don't. Incident rays parallel to the axis of a concave mirror
reflect from the mirror's surface and converge at its focal point.
Answer:
Below:
Explanation:
Consider two rays originating from the bottom of the pond. As these rays get refracted into the air, they bend away from the normal. ... This point gives the apparent position of the bottom of the pond, therefore, the pond appears to be shallower.
Hope it helps....
