Answer:
The shortest distance is 
Explanation:
The free body diagram of this question is shown on the first uploaded image
From the question we are told that
The speed of the bicycle is 
The distance between the axial is 
The mass center of the cyclist and the bicycle is 
behind the front axle
The mass center of the cyclist and the bicycle is 
above the ground
For the bicycle not to be thrown over the
Momentum about the back wheel must be zero so
=> 
=> 
Here 
So 
Apply the equation of motion to this motion we have
Where 
and 
since the bicycle is coming to a stop
=>
Answer:
Please find here some hints :
Rule. Newton’s second law, or fundamental principle of dynamics, mentions that a resultant force exerted on an object is always equal to the product of the mass of that object by its acceleration. ... Each force applied to an object causes this object to accelerate in the direction of the force applied.
Is acceleration a force?
The acceleration force, sometimes called the inertia force, is the vehicle’s resistance to speed variations. It holds you back when you increase your speed and pushes you back when you slow down.

Answer:
Radiation heat energy transfer
Explanation:
The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation
The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light
The radiant energy transferred from the Sun heats up the Earth, including the car's interior.
Answer:
B
Explanation: Because conduction is when an object touches another object and convection happens with boiling water or the water cycle, the particles/water fall and rise.
