Answer:
Focal length, f = 16 cm
Explanation:
Image distance, v = 24 cm
Object distance, u = -48 cm
We need to find the focal length of the lens. It can be determined using the lens formula as :
f = 16 cm
So, the focal length of the converging lens is 16 cm. Hence, this is the required solution.
Answer:
I don't understand your question ❓,the object.....of what experiment
Answer: In mechanics, the net force is the vector sum of forces acting on a particle or object. The net force is a single force that replaces the effect of the original forces on the particle's motion.
Explanation: Hope dis helps u
The average acceleration is -5.21 m/s² and the stopping time is 5.2 sec.
Given,
Final velocity, v = 0
Initial velocity, u = 61 mph
mph to km/h
u = 97.6 km/h
Or, u = 27.11 m/s
Displacement, s = 231 feet
Or, s = 70.4 meter
By using the third equation of motion, we get
v² - u² = 2as
0 - (27.1)² = 2 × a × 70.4
Or, acceleration(a) = -5.21 m/s²
Now, by the first equation of motion,
v = u + at
Or, - u = at
-27.11 = -5.21 × t
Or, t = 27.11/5.21
t = 5.2 sec
The stopping time (t) is 5.2 sec
Hence, the average acceleration is -5.21 m/s², and the time is 5.2 sec.
