Which object will have greater acceleration? Why?​

Physics

Answer:

Object D

Explanation:

Use Newton's Second Law to determine the acceleration that each object has.

  • F = ma

The force applied in both cases is 50 N, but the mass for object C and object D is different.

Let's start with object C first:

  • F = ma
  • 50 N = 10 kg · a
  • 50 = 10a
  • 5 = a

The acceleration object C undergoes is 5 m/s².  

Now let's calculate object D next:

  • F = ma
  • 50 N = 2 kg * a
  • 50 = 2a
  • 25 = a

The acceleration object D undergoes is 25 m/s².

Object D has greater acceleration because it has a smaller mass. The object with a smaller mass will accelerate more in order to satisfy Newton's 2nd Law.

the magnitude of the magnetic field at point p for a certain electromagnetic wave is 2.21. What is the magnitude of the elctic f
vesna_86 [32]

Answer:

6.63\times 10^8\ N/C

Explanation:

Given that,

The magnitude of magnetic field, B = 2.21

We need to find the magnitude of the electric field. Let it is E. So,

\dfrac{E}{B}=c\\\\E=Bc

Put all the values,

E=2.21\times 3\times 10^8\\\\=6.63\times 10^8\ N/C

So, the magnitude of the electric field is equal to 6.63\times 10^8\ N/C.

Alexus [3.1K]

Answer:

The nodes and anti nodes would reverse roles.

Explanation:

I believe it has to do with the path differences. If waves are in phase, then the path differences are such that the waves reach the screen with crests superimposing crests and troughs superimposing troughs. This happens when the periods of each wave are equal or the paths themselves differ by a whole number multiple of the wavelength (λ, 2λ, 3λ, ...).

Now make these waves out of phase. Then half of the waves will travel half a wavelength farther than the rest. So the path difference will be 0.5λ, 1.5λ, 2.5λ, ....

The unit of current, the ampere, is defined in terms of the force between currents. Two 1.0-meter-long sections of very long wir
Paha777 [63]

Answer:

1.6 x 10^{-7} N

Explanation:

If the force between two actual wires has this value, the current is defined to be exactly 1 A.

The force between two parallel wires carrying current can be defined as,

F=  μI_{1} I_{2} L/ 2πd

where,

current I_{1} = 1Amp

current I_{2} = 2amp

Length 'L'= 1m

distance 'd'= 2.5m

permeability of free space 'μ'= 4πx10^{-7} N/m

Putting the above values in the equation,

F=( 4πx10^{-7} x 1 x 2 x 1 )/ 2πx2.5

F= 1.6 x 10^{-7} N
