when is the object at rest? in constant speed? accelerating?
Answer:
Answered in explanaion.
Explanation:
REST: When an object does not change its position with respect to its frame of reference or surrounding, then the object is said to be in the state of rest.
CONSTANT SPEED: When the object covers equal distance in equal intervals of time, the object is said to be moving with constant speed.
ACCELERATING: An object is said to be accelerating when the speed of the object increases with respect to time.
A car is driving along a road at a speed of 50 km/hr. How far will the car travel in 5 hours?
Answer:
I think it's 250
Explanation:
If the car is traveling 50 km/hr that means every hour, the car drives 50 km. So if you want to know how far it will go in 5 hours you do 50x5.

what is lateral shift
Answer:
Lateral Shift When a ray of light is incident on a glass slab, the emergent ray coming out of the slab will be parallel to the incident ray. The perpendicular distance between the direction of incident ray and emergent ray is called the lateral Shift. It is denoted by d.

Two students move a box to the left. One student pushes with a force of 100 N to the left, and the other student pulls with a force of 85 N to the left. They move the box 20 m in 7 s. What is the total amount of work done on the box by the students?
Answer:
Resultant Force= F1 - F2
F1= 100N
F2= 85N
Resultant Force= 100N - 85N
R.F = 15N
Workdone= Force x Displacement
Force = 15N
Displacement = 20m
= 15N X 20m
=300Nm or Joules

19. A car accelerates uniformly in a straight line from 10 m/s to 20 m/s in 5 seconds. What is the
acceleration?
Answer:
2 [tex]m/s^{2}[/tex]
Explanation:
Acceleration = [tex]\frac{Final velocity-Initial velocity}{Time}[/tex]
= [tex]\frac{20 - 10}{5}[/tex]
= [tex]\frac{10}{5}[/tex]
= 2 [tex]m/s^{2}[/tex]
A marble is thrown horizontally with a speed of 15.0 m/s from the top of a building. When it strikes the ground, the marble has a velocity that makes an angle of 65.0° with the horizontal. From what height above the ground the marble was thrown. How far from the base of the building, did the marble land?
at what distance from a 2.45*10^-6 C charge will the electric field be 100 N/C?
Answer:14.8
Explanation:
Trust me
The distance will be = 14.85 m
What is electric field ?A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
given :
Charge (q)= 2.45*[tex]10^{-6}[/tex] C
Electric field (EF) = 100 N/C
to find = ? distance (r)
Electric field = 1/4π∈o * (q/[tex]r^{2}[/tex])
100 = 9 * [tex]10^{9}[/tex] * ( 2.45*[tex]10^{-6}[/tex] / [tex]r^{2}[/tex])
[tex]r^{2}[/tex] = 220.5
r= [tex]\sqrt{220.5}[/tex]
r = 14.85 m
The distance will be = 14.85 m

What causes the apparent colors of the objects we see?
Answer: The human eye and brain transform light into color. Allowing us to see them.
Explanation: Light receptors within the eye turn light into color. The color that is reflected off of an object, is what we see. Hope this helps.
The apparent colors of the objects we see causes due to reflection of the light which they absorb and emit.
What is reflection?Reflection is the change in direction of a wavefront which occurs at an interface present between the two different media so that the wavefront of the wave returns into the medium from which it has been originated. Common examples of reflection include the reflection of light, sound wave and water waves.
The color of an object is the wavelengths of light waves that it reflects. The reflection is determined by the arrangement of electrons in the atoms of that substance which will absorb and re-emit photons of particular energy levels according to the quantum laws.
