Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = T[/tex]
Hence ,option B is correct ✓
explain Newtons Laws
1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”
This law also called law of inertia
2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”
3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.
These forces are called action and reaction forces

You push on a light object (small mass) with a certain amount of force and it moves. If you push just as hard on a heavier object (large mass) it will move _____ the light object. a. Faster than b. slower than c. the same as
Answer: B
Explanation:
It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force
A toy rocket has a mass of 2.0 kg. The rocket has a force of 8.0 N acting on it. What is the acceleration of the rocket?
6.0 m/s^2
0.25 m/s^2
16.0 m/s^2
4.0 m/s^2
Answer:
force=mass × acceleration
8=2 × acceleration
acceleration= 8/2= 4 m/s²
Answer:4 m/s²

You push a box at a constant speed of 5m/s and let it go. It stops 1.5s later due to the force of friction. If you push the box at a speed of 12m/s, how long will it take to stop?
Answer:
the time taken for the box to stop is 3.6 s.
Explanation:
Given;
initial speed with which the box was pushed, u = 5 m/s
time taken for the box to stop, t = 1.5 s
Assuming the box is moving at constant acceleration, a;
[tex]a = \frac{u}{t} \\\\a = \frac{5}{1.5} \\\\a = 3.33 \ m/s[/tex]
When the box is pushed a speed of 12 m/s, the time taken for the box to stop is calculated as;
[tex]t = \frac{v}{a} \\\\t = \frac{12}{3.33} \\\\t = 3.6 \ s[/tex]
Therefore, the time taken for the box to stop is 3.6 s.

A cars velocity changes from 0 m/s to 30 m/s in 10 seconds. Calculate acceleration.
Answer:
3 m/s^2
Explanation:
acceleration = vf-vi/t = (30 m/s-0 m/s)/10 s = 3 m/s^2
A person is standing on the edge of a merry-go-round that has a radius of 2.0m is travelling at 5m/s. How long does it take for them to complete one lap?
Answer:2.51 s
Explanation:
Given
The radius of merry-go-round r=2 m
Speed of person at edge v=5 m/s
The person is in a uniform circular motion with constant velocity
time taken to complete one lap is
[tex]t=\frac{\text{distance}}{\text{speed}}=\frac{2\pi \cdot 2}{5}\\\\t=\frac{12.568}{5}=2.5136\ s[/tex]
A 500 N force is applied to an object accelerating at 25 m/s^2.
what is the mass of the object?
Answer:
there are go fella hope u understood
The mass of the object is 20 g
The first step is to write out the parameters given in the question
Force- 500 N
acceleration= 25 m/s²
mass= force/acceleration
= 500/25
= 20
Hence the mass of the object is 20g

An open pipe on an organ creates
a fundamental frequency at
10500 Hz. How long is the pipe?
Answer:
L = 1.61 cm
Explanation:
The frequency of open organ pipe is given by :
[tex]f=\dfrac{nv}{2L}[/tex]
Where
n = 1 for fundamental frequency
f = 10500 Hz
L is the length of the pipe
v is the speed of sound, v = 340 m/s
So,
[tex]L=\dfrac{nv}{2f}\\\\L=\dfrac{1\times 340}{2\times 10500 }\\\\L=0.0161\ m\\\\or\\\\L=1.61\ cm[/tex]
So, the length of the pipe is 1.61 cm.

why are north and south poles important to magnets
Answer:
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

What helps a race car to not slide all over the race track?
Answer: Gently reduce pressure on brakes – if on ice, push in the clutch to let the wheels turn freely.
Turn the steering wheel quickly – look and steer in the direction you want to go.
Counter-steer – as the vehicle gets back on course, counter-steer to avoid skidding in the opposite direction.
