Acceleration = (change in speed) / (time for the change)
change in speed = (speed at the end) - (speed at the beginning)
Our cyclist's change in speed = (3 m/s) - (8 m/s) = -5 m/s
Acceleration = (-5 m/s) / (60 seconds)
<em>Acceleration = -1/12 m/s²</em>
Answer: 294 N
Explanation:
Since the Normal Force
is equal to the weight
of the dog, we have:

Where:
is the mass of the dog
is the acceleration due to gravity on the Earth's surface
Solving:


Answer: Analog transfer information quicker, example electromagnetic waves which are used in our modern day phones.
Explanation: Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. Signals are composed of only two possible values: 0 or 1.
Answer:
B) It is connected in parallel and measures potential differences.
Explanation:
A voltmeter measures electrical potential differences between two points in an electric circuit. It is also connected in parallel to measure a device's voltage, while an ammeter is connected in series to measure a device's current.
Hope this helps! :)
Answer:
.15s
Explanation:
Follow the units here. If you divide 300.000m by 2000m/s then you'll end up with the meters reduced and just the seconds. So that's what you do to get the time:
(300.000m)/(2000m/s ) =
(300.000/2000)(m•s/m) =
0.15s
