Which explanation BEST supports Newtons second law of motion

Answers

Answer:

c

Explanation:

because newton's second law states that F= MA

which suggests that if M increases, F also increases which is the force,

let me give you a tip, during exam, just type any random numbers into the formula, like at first you type 5 into the M, then increase M, by putting 10 into the M , keep the acceleration the same for this, okay?

you will see that the force will increase,

by this I mean that option says largest mass, so the force will also be very big because in reality do you use more force on heavier box or a lighter one to push it across the room?

so larger mass, larger force, greater acceleration

but the question is not being clear, whether to the force remains constant for every object, if it does then A is false . and B is false because if the forces is constant, and it is light, it would require a small amount of force ,

but the other options, gave us a clue about the force so you can choose either c or d but see the explanation above,

the only corrext option will be c.

if not, please report this, someone will have a go at it

A wave can travel through a solid, liquid or gas or no matter at all
True or false?

Answers

Answer is TRUE

Waves carry energy through empty space or through a medium without transporting matter. While all waves can transmit energy through a medium, certain waves can also transmit energy through empty space. A medium is a material through which waves can travel. It can be a solid, liquid, or gas.

TRUE or FALSE: An object's mass changes depending on which planet it is located.
A. TRUE
B. FALSE

Answers

Answer:

Fales

Explanation:

That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

calculate capacitance if Q=7mc and delta V=12V​

Answers

Answer:

Capacitance = 0.00058 Farads

Explanation:

Given the following data;

Charge, Q = 7mC to Coulombs = 7/1000 = 0.007C

Velocity = 12V

To find the capacitance;

Capacitance = charge/potential difference

Substituting into the equation, we have;

Capacitance = 0.007/12

Capacitance = 0.00058 Farads

According to Newton’s second law of motion, what is equal to the acceleration of an object?

Answers

Answer:. The acceleration of the object is directly proportional to the force and inversely proportional to the mass.

Explanation:

According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration.

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

Answers

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

Given ↷

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 2k

so,

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 ✓

Answers

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.
