Answer:
Zero
Explanation:
As we know that the force and the motion direction should always be perpendicular to each other due to which the work is done by static friction be zero
Therefore
F.dcos(theta) = F.d cos(90) = 0
Hence, the work done by static friction is zero
Therefore the same is to be considered
It’s acceleration is 0 if it was traveling at a constant speed
C. Physicalist chemist and biologist conducted experience in gather collection that changed existing scientific knowledge about the oceans
Explanation:
The voyage of Her Majesty's Ship was highly important because it furnished scientists with rich evidence about a lot of phenomenon under study and this changed existing scientific knowledge about the ocean.
- H.M.S II was an expedition to study and map the ocean floor using some sophisticated and newer devices.
- It was through this expedition that the theory of plate tectonics was modified and became a theory
- The bathymetry of the ocean floor was also carried out.
- The mid-oceanic ridge was discovered through the expedition.
- Some rare species of organisms were also obtained from the ocean floor in this process.
- The H.M.S second expedition after the world war was very crucial and helped furthered scientific knowledge about the oceans.

The definition of average acceleration allows to find the result for the average acceleration in the given time interval is:
Instantaneous acceleration is defined as the derivative of velocity with respect to time.
a =
Where a is the acceleration, v the velocity and t the time.
They indicate that the speed of the car is given by the relation.
v = α t + β t²
With α = 3 m / s and β = 0.1 m / s³
Let's make the derivative.
a = α + 2β t
Let's substitute
a = 3 + 2 0.1 t
Average acceleration is the change in velocity in the time interval.
Let's find the velocity at the indicated time.
For t = 5 s
v₅ = 3 + 0.1 5²
v₅ = 5.5 m / s
For t = 10 s
v₁₀ = 3 + 0.1 10²
v₁₀ = 13 m / s
Let's calculate the average acceleration.
In conclusion using the definition of mean acceleration we can find the result for the mean acceleration in the given time interval is:
1.5 m / s²
