Answer:
a large matters of body with no shape is mass
Answer:
F=23N
Explanation:
The net force applied on the suitcase is the sum of the force F the man applies, the friction, the weight and the normal from the ground. We need only to look at the horizontal component of the forces to solve the question asked. On the horizontal, the net force would be the horizontal component of F minus the frictional force f, which always opposes movement (all the other forces are on the vertical component). So we have:
We now apply Newton's second Law on the horizontal:
And we calculate the horizontal component of F as , so we have
And to solve for F we do:
And substitute our values:
Answer:
Explanation:
1. The law that best illustrate this is Newton's first law of motion, which is also called the law of inertia
The law states that every object will continue in the sate of rest or in uniform motion except it is acted upon by an external force. The bike stop moving because it hits a curb.
Inertia: This is the reluctance or the tendency for a body to be in its state of rest or uniform motion.
And Maya is thrown into the air due to it inertia.
2. The Law that best illustrate this is Newton's Third law of motion.
This law states that to every action there is an equal and opposite reaction.
As the bird uses his wind to push air downward, air pushes upward on the bird allows it to fly. the upward and downward movement of air are both equal but opposite reaction.
3. The Law that illustrate this is Newton's second law of motion.
This law can be summarize as force is directly proportional to mass and acceleration.
Because the mass of the second box is smaller than the first box that was why its accelerate at a greater rate.

Explanation:
= thickness of the floor = 0.159 m
= thermal conductivity of wooden floor = 0.141 Wm⁻¹ ⁰C⁻¹
= Temperature of the interior of the cabin = 18.0 ⁰C
= Temperature of the air below the cabin = - 16.4 ⁰C
Difference in temperature is given as
= Difference in temperature = ⁰C
= Area of the floor = 13.4 m²
= Rate of heat conduction
Rate of heat conduction is given as
W
Its C. a decrease in the radius and an increase in the tangential speed ,I'm 100% sure
