Answer:
Multiply the acceleration by time to obtain the velocity change:
Example:
Velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h
Force is indirectly proportional to the distance. Therefore when the distance increases the force of attraction increases and the answer would be B
Answer:
The force is
Explanation:
From the question we are told that
The volume of blood ejected is 
The velocity of the ejected blood is 
The mass density of blood is 
The heart rate is 
Generally the average force exerted is mathematically represented as

=> 
=>

Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
