Answer:
a) v=1.36f
b)m=.36
c) real
d) Inverted
Explanation:
a)
In this question we have given,
object distance from converging lens,u=-3.78f
focal length of converging lens,=f
we have to find location of image,v=?
and magnification,m=?
we know that u, v and f are related by following formula
.............(1)
put values of f u in equation (1)
we got,
or
v=1.36f
b) Magnification, 
c)
Here the object is located further away from the lens than the focal point therefore image is real image and inverted.
d) image is inverted
The average speed is 0.55 m/s
<h3>What was his displacement?</h3>
Displacement is defined as the change in position of an object.
Mathematically,
D = Initial value - Final Value
D = 30 - 5 = 25m
Now , We have to find the average velocity,
Average velocity is calculated by the formula V = D/t,
where V equals the average velocity, D equals total displacement and t equals total time.
V = D/t
V = 25 m / 45s
V = 0.55 m/s
So , The average speed is o.55 m/s

Answer: Well there is a simple solution which is death..
Answer:
(a) 62.5 m
(b) 7.14 s
Explanation:
initial speed, u = 35 m/s
g = 9.8 m/s^2
(a) Let the rocket raises upto height h and at maximum height the speed is zero.
Use third equation of motion
h = 62.5 m
Thus, the rocket goes upto a height of 62.5 m.
(b) Let the rocket takes time t to reach to maximum height.
By use of first equation of motion
v = u + at
0 = 35 - 9.8 t
t = 3.57 s
The total time spent by the rocket in air = 2 t = 2 x 3.57 = 7.14 second.
