Answer:
To find the distance, use the formula for distance d = st, or distance equals speed times time.

Answer: Light reflects when it hits a surface.</h2>
Explanation:
It is now clear that light behaves as a wave and as a particle. It should be noted that the first to propose the <u>corpuscular theory </u>of light was <u>Issac Newton</u>, while the <u>wave theory</u> was initially proposed by <u>Christian Huygens</u>, who was contemporaneous with Newton.
Now, focusing on the corpuscular theory, <u>Newton proposed that light is composed of tiny massless particles, traveling in a straight line and at high speed.</u> In addition, he used the reflection phenomenon of the of light to show that it behaved like particles that when hitting a mirror were reflected by a perfectly elastic collision.
Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy
Spring potential energy =potential energy due to elevation
0.5*k*x²= mg=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy
spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*
10812.88 *2.3²=430*
=11.53 m/s
Compressions are the areas of high pressure while rarefractions are low pressure area
Answer:
t = 3.3 s and V = 15 m/s
Explanation:
Given that,
Distance covered by the car, d = 50 m
Initial speed, u = 5 m/s
Final speed, v = 25 m/s
Firstly we can find the acceleration of the car using third equation of motion. i.e.
Let t is the time taken by the car to occur this.
Let v is the average velocity of the car. It can be calculated as follows :
So, the time taken by the car to occur this is 3.3 seconds and the average velocity of the car is 15 m/s.
