Answer:
8.6 m/s
Explanation:
We can find the final velocity of the dog by using the following SUVAT equation:

where
u is the initial velocity
a is the acceleration
d is the distance covered
For the dog in the problem, we have
u = 1.5 m/s

And the distance covered is
d = 3.0 m
Therefore, we can re-arrange the equation to find the final velocity, v:

d. Maintain constant velocity
Explanation:
A constant velocity leads to no acceleration.
Acceleration is defined as the change in velocity with time:
Acceleration = 
If there is no change in velocity i.e constant velocity.
At constant velocity, the change in velocity is 0.
If we put zero in the equation above, we will obtain an acceleration value of 0.

Answer:
While a body is said to be in motion if it changes its position with respect to immediate surroundings.
A body is said to be in uniform motion if it covers equal distances in equal interval of time.
A body is said to be in non-uniform motion if it covers unequal distances in equal interval of time or vice-versa
Answer:
B. 9.0 V
Explanation:
In parallel circuits, the voltage across each circuit is the same across each component, which is also equal to the total voltage of the power supplied. So in this case, the voltage across each resistor is still 9.0V.
The voltage only changes when the resistors can connected in series.
Mass/volume is density so it’s 562g/72cm^3 so it’s roughly 7.805g per cubic centimeter
