Answer:
The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.
Explanation:
- According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."
- In mathematical term, F=ma. where F= force, m= mass, a= acceleration.
- So, by performing the calculation,
- 12N force will move the boy along with the wheel chair.

Question 11- d
Answer:
The answer is hyper-tonic.
Explanation:
The hyper-tonic fishes are found in freshwater. In these fishes, their blood conveys a lower water focus than the encompassing freshwater. With the death of freshwater by means of the mouth over the layers of the gill, the particles of water diffuse from the freshwater into the blood as a natural side effect. These fishes need to create an extremely tremendous amount of pee to offset this abundant utilization of water. These fishes therefore deliver little measures of concentrated pee.
