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.

<h3>What is force?</h3>
  • The word "force" has a specific meaning in science.
  • At this level, calling a force a push or a pull is entirely appropriate.
  • A force is not something an object "has in it" or that it "contains."
  • One thing experiences a force from another.
  • There are both living things and non-living objects in the concept of a force.
  • Force is used to describe a body's tendency to modify or change its state as a result of an external cause.
  • When force is applied, the body can also alter its size, shape, and direction. kicking a ball, pushing and pulling on the door, or kneading dough are a few examples.
  • The newton, abbreviated N, is the SI unit of force.

Light with a single wavelength falls on two slits separated by 0.510 mm. In the resulting interference pattern on a screen 2.24
scZoUnD [109]

Answer: 655.7 nm

Explanation:

Given

The slits are separated by d=0.510\ mm

Distance between slits and screen is D=2.24\ m

Adjacent bright fringes are \beta =2.88\ mm apart

Also, the distance between bright fringes is given by  

\Rightarrow \beta =\dfrac{\lambda D}{d}\quad [\lambda=\text{Wavelength of light}]\\\\\text{Insert the values}\\\\\Rightarrow 2.88\times 10^{-3}=\dfrac{\lambda \cdot 2.24}{0.510\times 10^{-3}}\\\\\Rightarrow \lambda =\dfrac{2.88\times 10^{-3}\times 0.510\times 10^{-3}}{2.24}\\\\\Rightarrow \lambda =0.6557\times 10^{-6}\ m\\\Rightarrow \lambda =655.7\ nm

mrs_skeptik [129]

Answer:

Explanation:

2) From F=ma

Force =15×40=600N or kgm/s2

3)From the same equation making acceleration the subject of the formula will give

a=f÷m

=24÷4=6m/s2

4)m=f÷a

=45÷15=3kg
