It takes the car 14 seconds to stop
Explanation:
A car is traveling at a constant velocity of 19 m/s when the driver puts
on the brakes to accelerate it at -1.4 m/s² until stopped
1. The initial velocity is 19 m/s
2. The acceleration is -1.4 m/s²
3. The final velocity is zero
We need to find how long it takes the car to stop
We can find the time by using the rule
→ v = u + a t
where v is the final velocity, u is the initial velocity, a is the
acceleration and t is the time
→ v = 0 m/s , u = 19 m/s , a = -1.4 m/s²
Substitute these values in the rule
→ 0 = 19 + (-1.4) t
→ 0 = 19 - 1.4 t
Add 1.4 t to both sides
→ 1.4 t = 19
Divide both sides by 1.4
→ t = 13.57 ≅ 14 seconds
It takes the car 14 seconds to stop

Answer:
The speed of the stone is 0.6138 c.
(B) is correct option.
Explanation:
Given that,
Mass of stone m= 0.6
Relativistic mass = 0.76
We need to calculate the speed
Using formula of rest mass
Put the value into the formula
Hence, The speed of the stone is 0.6138 c.
Answer: Two men who helped in the development of psychology in Germany was Wilhelm Wundt, and in United States was William James.
Explanation:
Wilhelm Wundt was a German scientist, who was the first person who introduced psychology. He studied the conscious experience as a part of scientific study. It emphasis the identification of the components of the consciousness. Introspection is the process through which conscious experiences can be analyzed.
William James was a scientist, native of U.S. His purpose was to study the function of behavior all over the world. This perspective was known as functionalism. This emphasizes over the fact that how mental activities helps how organisms fit into its surrounding environment.
