Answer:
1.) 113500J
2.) 237m
Explanation:
Hello!
To solve this exercise follow the following steps, the description and complete process is in the attached image
1. Draw the full sketch of the problem.
2. The work is defined as the product of the trajectory by the force that is parallel to this direction, for this reason to find the work done we multiply the horizontal distance (250m) by the applied force (454N)
3. The potential energy is equal to the product of mass, gravity and height and is equal to the work done by the force applied by the cyclist, of this relationship and using algebra we can find the height that the cyclist climbed
4. We use the sine function to find the diagonal distance using the height and angle of the slope
Answer:
Silver halide or silver salt is mostly used in photographic films
Explanation:
Silver halide crystals in gelatin are coated onto a film base, glass or paper substrate. And when a sliver halide crystal is exposed to light (photons strike) it turned into a small speck of metallic crystal and these comprise the invisible or latent image which is developed afterwards.

According to the law of universal gravitation, which is a classical physical law that describes the gravitational interaction between different bodies with mass:
Where:
is the module of the force exerted between both bodies
is the universal gravitation constant.
and 
are the masses of both bodies.
is the distance between both bodies
In this case we have a gravitation force 
, given by the formula written at the beginning. Let’s rename the distance as 
:
(1)
And we are asked to find the gravitation force 
with a given distance of 
:
(2)
The gravity constant is the same for both equations, and we are assuming both masses are constants, as well. So, let’s isolate 
in both equations:
From (1):
(3)
From (2):
(4)
If (3)=(4):
(5)
Now we have to find :
(6)
If 
:

The value of the acceleration is 0.76 m/s² and the total time taken by the vehicle is 39 seconds.
<h3>Acceleration of the vehicle</h3>
The acceleration of the vehicle before coming to rest is calculated as follows;
v² = u² + 2as
where;
- v is the final velocity
- u is the initial velocity
- a is the acceleration
- s is the distance traveled before stopping
the car came to rest with constant velocity attained after 12 seconds.
the initial velocity of the car before 12 seconds is zero.
v² = 0 + 2as
a = v²/2s
a = (10²)/(2 x 66)
a = 0.76 m/s²
<h3>Time of motion of the vehicle</h3>
d = ut + ¹/₂at²
where;
- d is the total distance traveled
- t is the time of motion
- a is acceleration
- u is initial velocity of the vehicle
580 = 0 + ¹/₂(0.76)t²
580 = 0.38t²
t² = 580/0.38
t² = 1,526.3
t = √1,526.3
t = 39 seconds
Thus, the value of the acceleration is 0.76 m/s² and the total time taken by the vehicle is 39 seconds.
