Answer:
Yes
Explanation:
[tex]v = \frac{ds}{dt} \\ where \: we \: need \: to \: know \\ \: change \: in \: displacement \\ \: and \: the \: time \: taken[/tex]
if you know the time it took an object to travel between two points and the position of the object at the points, then we can determine the object's instantaneous velocity by using the differential rate of the displacement function with respect to the time.
Instantaneous velocity = [tex]\frac{dS}{dt}[/tex]
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
velocity= displacement / time taken
for instantaneous velocity = [tex]\frac{dS}{dt}[/tex]
Thus, If you know how long it took an item to go between two places and where it was when it got there, you can use the differential rate of the displacement function with respect to time to calculate the object's instantaneous velocity.

1. State Newton's third law of motion and write any three applications of it
Answer:
1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun. 2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
Newton's Third law: when object A exerts force on object B, object B simultaneously exert oppositely directed force of equal magnitude on object A.
1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun.
2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

if the light is both wave and particle ..
then when light is said to be wave and when it is said to be particle ?
Answer:
Consider electrons incident on a Young's double slit
If one slit is covered, the electrons will form a maximum, on the screen, as if they were particles incident on the screen
If both slits are open, the pattern formed on the screen will be the same as if a wave were incident on the screen, even tho electrons are slowed to the point that only 1 electron is incident on the screen at one time.
That means that the electron interferes with itself to create the interference pattern on the screen, and there is no way to determine which slit the electron went thru without destroying the interference pattern.

energy

Energy I guess can be the answer

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

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.

Which statement best describes the energy of activation?
A.
It is not affected by a catalyst.
B.
It is lower if the reaction temperature decreases.
C.
It is higher if the reaction temperature increases.
D.
It is more quickly overcome when the temperature increases.
hi <3
i believe the answer would be D, as when the temperature increases the particles have more energy and can overcome the activation energy more rapidly.

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.

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.

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 :
[tex]v = u + at[/tex][tex]50 = 80 + 120a[/tex][tex]50 - 80 = 120a[/tex][tex]a = \dfrac{ - 30}{120} [/tex][tex]a = - \dfrac{1}{4} m/s {}^{2} [/tex][tex] - 0.25 \: \: m/s {}^{2} [/tex]What is living being

Answer:
B. Psycology
Psycology is considered a social science while all the other choices are natural sciences.
Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.
What are natural sciences?Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.
These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.

[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]
