Answer:

Explanation:

Given parameters:

Distance covered  = 16m

Time  = 6s

Initial velocity  = 0m/s

Unknown:

Magnitude of the acceleration of the runner = ?

Solution:

To solve this problem, we have to apply the right motion equation which is given below;

     S  = ut + \frac{1}{2}  at²  

S is the distance

u is the initial velocity

t is the time taken

a is the acceleration

 Now, insert the parameters and solve for acceleration;

      16  = (0 x 6) + \frac{1}{2} x a x 6²

     16  = 18a

     a  = \frac{16}{18}   = 0.89m/s²

An electron moves with velocity v⃗ =(5.9i−6.4j)×104m/s in a magnetic field B⃗ =(−0.63i+0.65j)T. Determine the z-component of the
HACTEHA [7]

Answer:

Explanation:

Force on the electron = q ( v x B )

q = - 1.6 x 10⁻¹⁹

v = (5.9i−6.4j)×10⁴

B = (−0.63i+0.65j)

v x B = (5.9i−6.4j)×10⁴  x (−0.63i+0.65j)

= (3.835  - 4.032 ) x 10⁴ k

= - 1970 k

Force on the electron = q ( v x B )

= - 1.6 x 10⁻¹⁹ x -1970 k

= 3.152 x 10⁻¹⁶ k

z-component of the force on the electron

Fz = 3.152 x 10⁻¹⁶ N

A 24.8 tall object is placed in front of a lens, which creates a -3.09 cm tall image. What is the magnification?
OleMash [197]

Answer: 0.125

Explanation:

Given that the

Object height U = 24.8 cm

Image height V = 3.09 cm

Magnification M is the ratio of the image height to the object height. That is, divide the given image height by the given object height.

M = V/U

Substitute V and U into the formula above.

M = 3.09/24.8

M = 0.125

Magnification is therefore equal to 0.125 approximately
