Answer:
The net force applied to the car is zero.
Explanation:
We are given that a car is moving to the left with constant velocity.
When the car moving with constant velocity
Then, the final velocity=Initial velocity
Change in velocity=Final velocity- initial velocity=0
When change in velocity is zero then , acceleration of car

When acceleration is zero then, By Newtons second law

The net force applied on the car will be zero.
Option C:The net force applied to the car is zero.
Answer:
Increase in the temperature of water would be 0.9 degree C
Explanation:
As we know by energy conservation
Change in the gravitational potential energy of the cylinder = increase in the thermal energy of the water
Here we know that the gravitational potential energy of the cylinder is given as

here we have
h = 300 m
now we can say

now if the cylinder falls from height h = 100 m
then we have

now from above two equations


Answer:
all chemical reaction involved in early enough energy used to break bonds in reactants and energy released when you want from product
Edith a remake reaction absorb energy and epidemic reaction release energy flow of conversion of energy states that matter cannot be created or destroyed .
Answer:
Decomposers
Explanation:
Decomposers are organisms that gives the soil essential nutrients for new plants to grow.
These are micro-organisms that takes up dead and decaying organisms. They break and reduce them down into useful soil organic matter.
Organic matter are the remains of plants and animals that are very vital in the soil. They provide nutrients needed for plant growth.
Complex organic molecules are broken down into simple and useful ones which are needed for the growth of plants.
