The vector B will have two components and those components will be called resultant vectors.

<h3>What is a component vector?</h3>

A component vector is a unit vector that represents a given vector in a particular direction.

A vector can be represented in x - direction and y - direction.

  • x - component of the vector = Bcosθ
  • y - component of the vector = Bsinθ

Thus, the vector B will have two components and those components will be called resultant vectors.

The charge that passes a cross-sectional area A=10-4 m2 varies with time according
Anarel [89]

Answer:

Current = dQ/dt

or I = dQ/dt

Where I represents current.

Which is the rate of flow of charge.

Q=4 + 2t + t²

dQ/dt = 2 + 2t --- This is the relation that gives the instantaneous current.

At time t=2sec

dQ/dt = I = 2 + 2t

= 2 + 2(2)

=2 + 4

= 6A.

Arianna is experimenting with different materials to see which one will
sp2606 [1]

Answer:

Concrete

Explanation:

The speed at which sound propagates is medium dependent. As one of the forms of mechanical waves, sound requires a material medium for propagation from place to place.

  • Sound travels with the least speed in air because air particles are far apart and they are randomized.
  • Sound travels with the greatest speed in solids. Concrete is the only solid material given in the choice.

The speed of sound increases from air to liquid and to solid.

Carly's friends think she may be diving into pseudoscience .

  • When presented as pseudoscience, a claim, finding, or explanatory framework lacks the objectivity needed for scientific inquiry. Research that is based on dubious ideas, a defective experimental design, or unreliable data can also lead to pseudoscience.
  • The word "pseudoscience" can be used to describe a single assertion or claim that is allegedly supported by facts or science but falls apart when put to the test of reason.
  • A complicated system, like astrology, that claims to explain how astronomical occurrences cause and effect world events is another example of a pseudoscience. Many pseudosciences, like astrology, are reasonably safe.

Captain Hook is ghting Peter Pan, and they are about to step onto a tightrope strung horizontally between two maststhat are 16 m
andreyandreev [35.5K]

Complete Question

Captain Hook is fighting  Peter Pan, and they are about to step onto a tightrope strung horizontally between two masts that are 16 m apart. When Pan and Hook are standing exactly halfway between the masts, the rope makes a 3 anglewith the horizontal. The rope has a diameter of 0.02 m and a Youngs modulus of 35 GPa.

What is the combined mass,in kilograms, of Peter Pan and Captain Hook?

Answer:

Their combined mass is m= 161.2kg

Explanation:

A sketch that describes the question is shown on the first uploaded image  

  From the question we are told that

          The distance apart is d_A = 16m

          The angle the rope makes is \theta = 3^o

          The diameter of the rope is d = 0.02m

          The Young modulus is  Y = 35Pa

From the diagram we see that the elongation of the rope can be  mathematically evaluated as

         \Delta L = 2x - 16

And applying  SOHCATOH rule    x = \frac{8}{cos \theta}

   Substituting values

                              x = \frac{8}{cos (3)}

                                = 8.01m

      And   \Delta L = \frac{16}{cos 3}  -16

                     \Delta L = 0.02196m

The Tension on the rope can be mathematically represented as

               T = Y A * \frac{\Delta L}{L}

Where A is the area and is mathematically represented as

              A = \frac{\pi}{4} d^2

 Substituting values

            A = \frac{\pi}{4} (0.02)^2

Now Substituting values into the formula for the tension on the rope

          T = (35*10^9) * \frac{\pi}{4} (0.02)^2 * \frac{(0.02196)}{16}

             =15093.4 N

From the diagram we can mathematically evaluate the the weight of peter and hook as

              W = 2T sin \theta

Where W = mg

Now substituting this into the equation and making m the subject

                   m = \frac{2Tsin \theta}{g}

Substituting values

                m = \frac{2* 15093.4 sin(3)}{9.8}

                    m= 161.2kg

Note  SOHCATOH is

                         Sin \theta = \frac{opposite}{hypotenuse}\\ Cos \theta = \frac{adjacent }{hypotenuse} \\Tan \theta = \frac{opposite}{adjacent}

In a minimum of two sentences, define a red giant and how a red giant forms.
Vadim26 [7]
Red Giants are the stars that currently in the late phase of the Stellar Revolution. One of the main features of a red giant is its variations on brightness.
Red Giants are formed because of the constant helium-burning process from the stars (which keep making it bigger and bigger) to the point where it almost ran out of it.
