Answer:
F = 172 N
Explanation:
Newton's second law of motion gives the amount of force acting on an object. Mathematically, it is given by :
F=ma
Put m =86 kg and a = 2 m/s²
So,
Hence, the net force is 172 N.
As the engine heats up, a natural circulation starts, as coolant rises through the engine block by convection. It passes through the top hose, and into the radiator. Inside the radiator, heat is removed from the coolant as it falls from the top to the bottom.

Answer: A student walks 50 meters east, 40 meters north, 35 meters east, and then 20 m south. Then the magnitude and direction of the student's total displacement will be 87.32 m along the direction of AD or in east-south direction.
Explanation: To find the correct answer, we need to know about the Displacement of a body in motion.
<h3>What is displacement of a body in motion?</h3>
- The displacement is the shortest distance between initial and final positions of a body.
- It's a vector quantity, and can positive, negative, or zero.
- The magnitude of displacement is less than or equal to the distance travelled.
<h3>How to solve the problem?</h3>
- At first, we can draw a diagram showing the motion of the body.
- From the diagram, the displacement of the body will be equal to the distance between point A and D.
- To solve this, we can use Pythagoras theorem.
Thus, from the above calculations, we can conclude that, the displacement of the body will be equal to 87.32 m along the direction of AD or in east-south direction.

The answer is the 4th option because they don't use oxygen, that's what they produce
Answer:
f = 0.84 m
Explanation:
given,
near point of the distance from eye(d_i) = 0.60 m
distance he can read (d_o)= 0.350 m
focal length of the contact lens = ?
now,
Using lens formula
f = 0.84 m
Hence, The focal length of the contact lens that person needed is equal to
f = 0.84 m
