Hydroelectric dams convert the gravitational potential energy of falling water into electricity.
a = acceleration of the bank cart = 4 m/s²
m = mass of the bank cart = 8000 kg
F = net force on the cart
According to newton's second law , Net force is the product of mass of the object and the acceleration of the object.
Net force = mass x net acceleration
hence Net force acting on the cart is given as
F = ma
F = 8000 x 4
F = 32000 N
hence the net force acting on the cart comes out to be 32000 N
Answer:
The correct option is;
2. Some of the laws that govern nature cannot be detected by scientists
Explanation:
The statement "some of the laws that govern nature cannot be detected by scientists" is a scientific claim because of the concept of the laws or the theories truth or realism
The art word 'scientific realism' refers to the world that cannot be observed with our natural given senses without an aid.
Ontic realism refers to the statement that the world that cannot be observed are independent from the entities that are in possession of minds, ideas, language conception
Therefore, according to the ontic realist consider the world to be made of unobservable structures and units that exist independent of the man.
This is the definition of specific heat capacity. 1000J of heat are required to raise the temperature of 1kg of the compound by 1 degree. Therefore a 1000J have been added to the block.
