Why are there only two elements in the first period of the periodic table?(1 point)
because the first two elements both start with H and are grouped together
because the next elements have other things in common and they need to be arranged together
because only two electrons can fit in the first orbit around the nucleus, and each period on the table is organized by number of orbits
because each row increases in atomic mass by a specific number, so anything over five is in the second row
Answer:
because each row increases in atomic mass by a specific number, so anything over five is in the second row.
difference between distance and displacement?
Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Explanation:
Distance is a scalar quantity as it only depends upon the magnitude and not the direction. Displacement is a vector quantity as it depends upon both magnitude and direction. ... The distance can be measured along a non-straight path. Displacement can only be measured along a straight path.
Answer:
displacement is a shortest distance between final point and initial point but distance is the total length of path.

While rowing in a race, John does 132 J of work while pulling the oar 0.800 m.
How much force do John's arms exert?
Answer:
i got u!!! john's arms exert a force of 165 newtons.
Hi there!
[tex]\large\boxed{F = 165 N}[/tex]
We know the equation:
W = F · d, where:
W = work (J)
d = displacement (m)
F = force (N)
We can rearrange to solve for F:
W/d = F
Thus:
132/0.8 = F
F = 165 N
Why is the perfect mechine is not possible in the real life?
Answer:
Because the mechanical advantage of the machine is affected by friction and weight but velocity ratio is not. So, mechanical advantage is less than velocity rate. Thus, the machine's efficiency is less than 100% and can't be a perfect machine
In Hindu chronology, the longest time measure is a para. One para equals 311 040 000 000 000 years. Calculate this value in megayears, hours and in seconds. Write your answers in scientific notation.
A para equals [tex]3.110\times 10^{8}[/tex] megayears, [tex]2.725\times 10^{18}[/tex] hours and [tex]9.809\times 10^{21}[/tex] seconds, respectively.
This is an unit conversion problem, in this question we need to convert a value in Hindu units into SI units. A megayear equals [tex]10^{6}[/tex] years, a year equals 8760 hours and a hour equals 3600 seconds. Now we proceed to perform all required conversions:
Megayears
[tex]x = 1\,para \times \frac{311040000000000\,yr}{1\,para} \times \frac{1\,Myr}{10^{6}\,yr}[/tex]
[tex]x = 311040000\,Myr[/tex]
[tex]x = 3.110\times 10^{8}\,Myr[/tex]
Hours
[tex]x = 1\,para \times \frac{311040000000000\,yr}{1\,para} \times \frac{8760\,h}{1\,yr}[/tex]
[tex]x = 2.725\times 10^{18}\,h[/tex]
Seconds
[tex]x = 1\,para \times \frac{311040000000000\,yr}{1\,para} \times \frac{8760\,h}{1\,yr} \times \frac{3600\,s}{1\,h}[/tex]
[tex]x = 9.809\times 10^{21}\,s[/tex]
A para equals [tex]3.110\times 10^{8}[/tex] megayears, [tex]2.725\times 10^{18}[/tex] hours and [tex]9.809\times 10^{21}[/tex] seconds, respectively.

I=2cm u=12cm o=0.5cm. What is the Focal length? and find u also
Answer:
Focal length is 4 cm
Explanation:
h2 = 2 cm (Erect image)
v = - 12 cm (Erect image)
h1 = 0.5 cm
m = v/u = h2/h1
-12/u = 2/0.5
u = -3 cm
lens formula : 1/v – 1/u = 1/f
1/-12 – 1/-3 = 1/f
(-1 + 4)/12 = 1/f
F = 4 cm

9. An object which is in circular motion (moving along a circle) is said to be accelerating because it changes it's direction constantly even if it is moving with a constant speed. cuz acceleration is change in either magnitude or direction of an object with respect to time.
therefore, it's still acceleration as change in direction with time.
10. Average speed of an object can be calculated by dividing the total distance covered by an object by time taken to cover that distance.
i.e
[tex] \boxed{speed = \dfrac{distance}{time} }[/tex]it can be re- arranged to find the distance as :
[tex] \boxed{distance = speed \times time}[/tex][tex]time = \dfrac{distance}{speed} [/tex]11. speed = 20 m/s : conversion into km/h
distance covered : 4 km = 4000 m
[tex]time = \dfrac{distance}{speed} [/tex][tex]t = \dfrac{4000}{20} [/tex][tex]t = 200 \: \: sec[/tex]time taken = 200 seconds
12. let's use the first equation of motion to find the acceleration :

If an object is projected horizontally from a height of 5 m with an initial velocity of 7 m/s, what is the value of x^0?
x0=−9.8 m/s2
x subscript 0 baseline equals negative 9.8 m per s squared
x0=0
x subscript 0 baseline equals 0
x0=5
x subscript 0 baseline equals 5
x0=7
The horizontal displacement (x₀) of the object is 7 m.
The given parameters;
height of the object projection, h = 5 minitial horizontal velocity of the object, uₓ = 7 m/sThe vertical displacement equation of the object is given as;
h = vt + ¹/₂gt²
where;
v is the initial vertical velocity = 0
The time of motion is calculated as;
5 = 0 + (0.5 x 9.8)t²
5 = 4.9t²
[tex]t^2 = \frac{5}{4.9} \\\\t^2 = 1.02\\\\t = \sqrt{1.02} \\\\t = 1 \ s[/tex]
The horizontal displacement of the object is calculated as;
X₀ = uₓt
X₀ = 7 x 1
X₀ = 7 m
Thus, the horizontal displacement (x₀) of the object is 7 m.

scientist use empirical evidence, logical thinking, and tests to ___ a scientific explanation.
Answer:
Explanation:
The only word I can think of is confirm.
I choose confirm because they have already used empirical evidence (evidence that is primarily found by the senses. We hear something, we see something, We smell something -- although this is rather rare. Probably we would hear or see something first). We've used logical thinking, and we've likely even performed experiments.
So we've done all the ground work. All of these things are needed to confirm a scientific thought or premise that has been proposed. All of them aim at confirming what we proposed.

Answer:
a. Value of MA is always lesser than VR because mechanical advantage decreases due to the friction and weight of moving parts of the machine.
b.Efficiency of lever is never 100 or more because it will always lose some tiny (sometimes immeasurable) percentage of power due to the lever bending.
c.Because it helps to apply more torque.
d.Because the upright snip has the blades rotated 90° from the handles.
e.because some of the input work is used to overcome friction.
f.because the load arm is always longer than effort arm.
g.because the effort arm is always longer than load arm of these Lever.
h. because if the effort distance is greater than load distance there will be magnification of force and the metals could easily cut.
i. because the wheelbarrow's wheel and axle help the wheelbarrow to move without friction thus making it easier to push or pull.
