Explanation:
Newton's second law states the "net force on a body is the product of its mass and acceleration".
When a body has a net force acting on it, it will change position and begin to move.
Ordinarily, a car will not move until it is towed when the engine is faulty. The weight of the car and the frictional force of the tire acts to prevent its motion.
Now, the towing van supplies a force that is greater than the weight of the car and the frictional force between the tires. This way the towing van is able to move the faulty car.

Answer:
Explanation:
Potential energy is energy due to position. It is the product of mass, height, and acceleration due to gravity.
The mass of the textbook is 1.85 kilograms. Assuming this is on Earth, the acceleration due to gravity is 9.8 meters per square second. The height is 2.23 meters.
- m= 1.85 kg
- g= 9.8 m/s²
- h= 2.23 m
Substitute the values into the formula.
Multiply the first 2 numbers together.
Multiply again.
- 1 kilogram square meter per square second (1 kg*m²/s²) is equal to 1 Joules (J)
- Our answer of 40.4299 kg*m²/s² is equal to 40.4299 J
The textbook has <u>40.4299 Joules of potential energy.</u>
A. a wide variety of hunting techniques
Explanation:
To help the fisher population to survive in a changing environment, they have to develop a wide variety of hunting techniques.
The new fisher population have to develop a wide range of strategies to satisfy its carnivorous instincts.
- Most predators are carnivores with a wide range of hunting skills
- They must be fast, subtle, good sighted and well adapted body part to hunt of preys.
- As they transcends different environments, they must have good and diverse hunting skills to give them a competitive advantage.
