The net force is <u>zero</u><u>.</u>
According to Newton's first law, every body continues in its state of rest or in a state of uniform motion in a constant direction, unless acted upon by an external unbalanced force. This law leads to the principle that no force is required to keep the body moving with a constant velocity.
According to Newton's second law, force acting on a body is proportional to the rate of change of momentum produced in the body. In simple terms, the force <em>F</em> acting on a body is given by the product of its mass and the acceleration produced in it. Thus, when a force acts on a body, the body is accelerated.
A body is said to be accelerated, if its speed changes or its direction changes or if both its speed and its direction changes.
Since the car in the question is travelling at a constant speed of 60 mph, it is not accelerated, hence the total external force acting on the car is zero.
Detergents are special, powerful cleansers that can break up dirt, oils, and grease in clothing or on dishes.
Cleaning solvents are used to remove oil, grease, solder flux, and other contaminants.
Acid cleaners are generally used to remove mineral deposits and are useful for descaling dishwashers or removing rust from restroom facilities.

QUESTION -
In which direction does energy flow in an ecosystem ?
ANSWER -
The flow of energy in an ecosystem is best described as energy moving in one direction from the sun to the producers then to the consumers. Explanation; Energy flow is the amount of energy that moves through successive trophic levels of a food chain in an ecosystem
