Vladimir [108]3 years ago
3 0

Answer:

Velocity is a vector quantity. It has both, magnitude and direction. Velocity is the rate of change in the position of a body with respect to a frame of reference. One component is the magnitude of velocity which is speed. The other one is its direction.

Explanation:

Speed is a scalar quantity.

Velocity is a vector quantity.

There are two types of quantities:

1. Scalar quantity:

A scalar quantity is a quantity which is described by its magnitude alone.

2. Vector Quantity:

A vector quantity is a quantity which is described completely by both, its magnitude and direction.

Two one-coulomb point charges are at a distance of 1.67 m from each other. What is the size of the electric force between the tw
pychu [463]

Explanation:

The given data is as follows.

       distance (r) = 1.67 m

     q_{1} = q_{2} = 1 C

It is known that formula for electric force between two charges is as follows.

          F = \frac{kq_{1} \times q_{2}}{r^{2}}

Hence, putting the given values into the above formula as follows.

       \frac{9 \times 10^{9} \times 1 \times 1}{(1.67)^{2}}

            = 3.227 \times 10^{9}

As it is given that mass of  Falcon Heavy rocket is 1421. Therefore, weight of 1 Falcon rocket is as follows.

       weight of 1 falcon rocket = 142 \times 10^{3} \times 9.8

Therefore, number of falcon rockets will be calculated as follows.

         No. of falcon rockets = \frac{3.227 \times 10^{9}}{142000 \times 9.8}

                              = 2.31897 \times 10^{3}

                              = 2318.9 falcons

Thus, we can conclude that force between the two point charges above is equal to the weight of 2318.9 Falcon Heavy rockets.

A periodic wave travels from one medium to another. which pair of variables are likely to change in the process?
Sav [38]

velocity and wavelength are likely to change in the process

  • When a wave travels from one medium to another it undergoes a change in direction and this is referred to as refraction.
  • Refraction is the bending of a wave or a change in direction of a wave as it travels from one medium to another. Refraction is accompanied by change in velocity and wavelength of a wave
