What is a primary source?
A.A textbook that explains a wide range of science topics
B.A technical article written by an experimenter
C.A newspaper article about a recent discovery
D.A summary of research written for an average reader
Answer:
Explanation:
B
A primary source is one that is written by the person who lived through an advenure or is one doing the action and recording it.
In this case, the answer is B.
Most frequently, for a historian, a primary source is something like a diary or a bunch of letter written by someone experiencing something.
It cannot be about someone else's work. Not C or D
A textbook is not the answer either. It is a bulky summary of scientific, or other kind of thought.

The speed of an object undergoing constant acceleration increases from 8.0 meters per second to 16.0 meters per second in 10. seconds. How far does the object travel during the 10. seconds?
Answer:
[tex] \boxed{d = 120\: meters} [/tex]
Explanation:
Given:
[tex] v_{0} [/tex] = 8.0 m/s[tex] v [/tex] = 16.0 m/s[tex] t [/tex] = 10 seconds[tex] d [/tex] = ?We can use this equation with the variables given to solve:
[tex] d \: = \frac{t \: (v + v_{0})}{2}[/tex] →
[tex] d \: = \frac{(10s) \: ((16.0 \: m/s) + (8.0 \: m/s))}{2} [/tex] →
[tex] d \: = \frac{(10s) \: (24 \: m/s)}{2} [/tex] →
[tex] d \: = \frac{(10 \: s \: • \: 24 \: m/s)}{2} [/tex] →
[tex] d \: = \frac{240 \: m}{2} [/tex] →
[tex] d \: = 120 \: m [/tex]
The distance traveled by the object in 10 seconds is 120 meters.
Given to us,
Final velocity of the object, [tex]v= 16\ meter/sec[/tex]
Initial velocity of the object, [tex]u= 8\ meter/sec[/tex]
Time for traveling, [tex]t= 10\ sec[/tex]
Using the first equation of motion, we can find out acceleration of the object [tex]a[/tex],
[tex]v=u+at\\16=8+a\times 10\\a= 0.8\ meter/sec^2[/tex]
Now using the second equation of motion and putting the value of [tex]a[/tex],
The distance[tex](S)[/tex] traveled by the object ,
[tex]\begin{aligned}S&= ut+\frac{1}{2}at^2\\&= 8\times 10+ \frac{1}{2}\times 0.8\times 10^2\\&= 120\ meters \\\end{aligned}[/tex]
Hence,The distance traveled by the object in 10 seconds is 120 meters.

¿Qué cantidad de calor absorbió una masa de 4 g de cinc al pasar de 20 °C a
180 °C?
(amount of heat)Q = ? , (Mass) m= 4 g , ΔT = T f - T i = 180 c° - 20 °c = 160 °c ,
Ce = 0.093 cal/g. °c
Q = m C ΔT
Q = 4 g × 0.093 cal/g.c° × ( 180 °c- 20 °c )
Q= 4×0.093 × 160
Q = 59.52 cal

a constant force acting on a body of mass 4kg changes its velocity from 2m/s to 4m/s in 4s. what is the force?
Answer:
2 Newton
Explanation:
from newton second law
F = ma
as we have the mass equals 4 kg
we need to get the acceleration which will be change in velocity over change in time
a = ∆V/∆t = (4-2)/4 = 0.5
so F = 4 * 0.5 = 2
Answer:2N
Explanation:
derivation of s= u+ 1/2 at2
We know that
Velocity is given by the rate of change of position w.r.t time
[tex]\\ \sf\longmapsto v=\dfrac{dx}{dt}[/tex]
[tex]\\ \sf\longmapsto vdt=dx[/tex]
Now we can see in above v is not independent of t .So we replace the value of v by v=u+at and we get[tex]\\ \sf\longmapsto (u+at)dt=dx[/tex]
Integrate with limits 0 to t and x_o to x respectively .[tex]\\ \sf\longmapsto u{\displaystyle{\int}_0^t}dt+a{\displaystyle{\int}_0^t}dt={\displaystyle{\int}^x_{x_0}}dx[/tex]
[tex]\\ \sf\longmapsto ut+\dfrac{1}{2}at^2=(x-x_0)[/tex]
[tex]\\ \sf\longmapsto x=x_0+ut+\dfrac{1}{2}at^2[/tex]

When is the car exceeding a 10 km/hr speed limit?
If the car travels a distance greater than 10 km in one hour or less than one hour, it has exceeded the speed limit.
The given parameter:
speed limit = 10 km/hour
To find:
when the car will exceed the speed limitSpeed is defined as the total distance traveled divided by the total time taken for the journey.
[tex]speed = \frac{distance}{time}[/tex]
If the car travels any distance greater than 10 km in 1 hour or less than 1 hour, it has exceeded the speed limit of 10 km/hr.
For example, let's say the distance traveled by the car in one hour is 11 km. The speed of the car is 11 km/hr which is greater than the speed limit.
Thus, we can conclude that if the car travels a distance greater than 10 km in one hour or less than one hour, it has exceeded the speed limit.
