**Answer:**

Acceleration of Sea Lion is 4.41 g

This is 49% of maximum jet acceleration given as a = 9g

**Explanation:**

As we know that the radius of the circular loop is given as

R = 0.37 m

The speed of the fish is given as

Now the centripetal acceleration of the sea lion is given as

as we know that

so we have

Now Percentage of this acceleration wrt maximum jet acceleration is given as

%

**Answer:d**

**Explanation:**

Drift velocity is given by

where =drift velocity

I=Current

n=no of electron

Q=charge of Electron

A=cross-section

If area of cross-section decreases gradually then drift velocity will increase because drift velocity is inversely proportional to Area of cross-section

The correct answer is the Sun.i hope that helped! if you have any questions or concerns about the answer i gave you please let me know!!

**Answer:**

**a.**

**b.1058 N**

**Explanation:**

We are given that

Mass of each dog,M=18.5 kg

Mass of sled with rider,m=250 kg

a.Average force,F=185 N

By Newton's second law

b.By Newton's second law

Substitute the values

Hence, the force in the coupling between the dogs and the sled=**1058 N**
