Answer:
See Explanation
Explanation:
The question is incomplete, as there are no diagrams or options to provide more information to the question.
The general explanation is as follows:
For the object not to move
(1): The forces acting on the object must opposite each other. i.e. if force A acts at the right (or positive direction), force B will act at the left (or negative direction).
(2) The two forces must be equal.
So, for instance:
If the pair of forces are 5N and 5N in opposite directions, the object wil not move.
However, if one of the forces is greater, the object will move towards the direction of the greater force.

briefly discuss university need based scholarships and explain them.
Answer: Scholarships are given to reduce the burden of finance to be payed for academics and learning.
Explanation:
The need based scholarships are given in the following matters:
1. Research based scholarships: Scholarships should be given to meritorious students to conduct research in a particular discipline.
2. Student fails to submit fees: The student if meritorious and family is not able to fees then university can either postpone the date for fees payment or can give some concession in fees or fund the student fees for a tenure. It is a kind of scholarship for meritorious students.
3. Teacher scholarships: Teachers are allowed to learn new teaching methodologies with other institutions so that they can help students to learn well. They are provided with scholarships to avail admission in those institutions.
A boom is to be dropped from moving helicopter on the ground. Explain how can it hut the target ?
Answer:
A bomb that is dropped from a moving helicopter doesn't fall directly downward rather it follows the parabolic path as it were thrown horizontally from a height with certain initial velocity. Therefore, the bomb should be dropped from farther distance equal to the horizontal range before the helicopter reaches above the target.
Why are the oceans movements along the What do ocean waves have in common with the sound and light
Answer:
Oceanic currents an waves are in motion due to energy of wind.
Explanation:
When the wind blows across the ocean water ts creates a pull and push effect. It pulls the top layers of water and creates a frictional drag force that leads to the movement of water molecules and appears that the surface is moving. The movement can be seen in the form of surface oceanic currents and waves that are found through the entire globe. The ocean waves and currents carry with them the energy from one place to another.
A student is trying to demonstrate static electricity, so they rub two identical balloons with a neutral rabbit fur to give them a charge. How
do these three objects now behave when brought near to each other?
o A. They all attract each other.
OB. The balloons repel each other but attract the rabbit fur.
C. They all repel each other.
D. The balloons attract each other but repel the rabbit fur.
Answer: The balloons repel each other but attract the rabbit fur.
Brainliest pwease if I could do you any help!
˙ᵕ˙Here, both the balloons gains a negative charge through rubbing and they attracts to the neutral rabbit fur. But the balloons themselves repel each other. Hence, option B is correct.
What is static electricity ?When a material rub on a surface its electrons gets aligned and acquire a negative charge. This negative charge when comes in contact with a neutral material, the second one get partially polarized and gets attracted to the negative charge.
This flow of electrons through induced polarization is called static electricity. When the balloon are rubbed with the neutral rabbit fur and gets negatively charged by friction.
This negatively charged balloons repel each other but they induce a polarity to the neutral rabbit fur and its positive charges gets aligned with the negative charges results in electrostatic attraction.

Xander reached a final velocity of 4.5 m/s for 3.5 seconds. Finley reached a final velocity of 3.6 m/s for 4.2 seconds. Max reached a final velocity of 7.3 m/s for 1.2 seconds. They all started at the same location from rest. Which lists them from least to most acceleration? Max Finley Xander Max Xander Finley Xander Finley Max Finley Xander Max
Answer:
Finley, Xander and Max
Explanation:
v = Final velocity
t = Time
u = Initial velocity = 0
a = Acceleration
From kinematic equations we get
[tex]v=u+at\\\Rightarrow a=\dfrac{v-u}{t}=\dfrac{v-0}{t}\\\Rightarrow a=\dfrac{v}{t}[/tex]
Xander
v = 4.5 m/s, t = 3.5 s
[tex]a=\dfrac{4.5}{3.5}\\\Rightarrow a=1.29\ \text{m/s}^2[/tex]
Finley
v = 3.6 m/s, t = 4.2 s
[tex]a=\dfrac{3.6}{4.2}\\\Rightarrow a=0.86\ \text{m/s}^2[/tex]
Max
v = 7.3 m/s, t = 1.2 s
[tex]a=\dfrac{7.3}{1.2}\\\Rightarrow a=6.083\ \text{m/s}^2[/tex]

What is the correct reason for blinking / flickering of stars? Explain it.
A) The blasts in the stars.
B) Absorption of star light by the atmosphere.
C) Motion of the stars.
D) Changing refractive index of gases in the atmosphere.
plz suggest me a answer which can give me 3 marks
Answer:
d. changing refractive index of gases in the atmosphere
Explanation:
light from a star passes through the atmosphere to reach our eyes. however, the layers of gases in the atmosphere are in constant motion, so the light gets bent and appears to be flickering.
i hope this helps! :D
Why is the sky blue? The earth is surrounded by an atmosphere.
Answer:
The blue component of the spectrum of visible light has shorter wavelengths and higher frequencies than the red component. Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. The faster the oscillation, the more scattered light is produced, so blue is scattered more strongly than red. For particles such as air molecules that are much smaller than the wavelengths of visible light the difference is dramatic. The acceleration of the charged particles is proportional to the square of the frequency, and the intensity of scattered light is proportional to the square of this acceleration. Scattered light intensity is therefore proportional to the fourth power of frequency. The result is that blue light is scattered into other directions almost 10 times as efficiently as red light.
8. What is the frequency of green light waves that have a wavelength of 5.2 x 10-7 m.? The speed of light is 3.0 x 108 m/s
Answer:
[tex]f=5.76\times 10^{14}\ Hz[/tex]
Explanation:
We need to find the frequency of green light having wavelength o[tex]5.2\times 10^{-7}\ m[/tex]. It can be calculated as follows :
[tex]c=f\lambda\\\\f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{5.2\times 10^{-7}}\\\\f=5.76\times 10^{14}\ Hz[/tex]
So, the required frequency of green light is equal to [tex]5.76\times 10^{14}\ Hz[/tex].
