Mass of Derrick at a height 4.3 m having 2730 joule of energy is 65 Kg.

<h3>What is the expression of gravitational potential energy near the earth surface?</h3>
  • Mathematically, gravitational potential energy near the earth surface= m×g×h
  • m= mass of Derrick, g= acceleration due to gravity, h= height at which Derrick present
  • Then, mass (m) of Derrick = potential energy/ (g×h)

<h3>What is the mass of Derrick, if he gains 2730 joule of energy at 4.3m above the ground?</h3>

Mass of Derrick= 2730/(9.8×4.3)

= 65 kg

Thus, we can conclude that the mass of Derrick is 65 Kg.

An electron is moving east in a uniform electric field of 1.55 N/C directed to the west. At point A, the velocity of the electro
valkas [14]

Answer:

Final velocity of electron, v=6.45\times 10^5\ m/s    

Explanation:

It is given that,

Electric field, E = 1.55 N/C

Initial velocity at point A, u=4.52\times 10^5\ m/s

We need to find the speed of the electron when it reaches point B which is a distance of 0.395 m east of point A. It can be calculated using third equation of motion as :

v^2=u^2+2as........(1)

a is the acceleration, a=\dfrac{F}{m}

We know that electric force, F = qE

a=\dfrac{qE}{m}

Use above equation in equation (1) as:

v^2=u^2+\dfrac{2qEs}{m}

v^2=(4.52\times 10^5\ m/s)^2+2\times \dfrac{1.6\times 10^{-19}\ C\times 1.55\ N/C}{9.1\times 10^{-31}\ kg}\times 0.395\ m

v = 647302.09 m/s

or

v=6.45\times 10^5\ m/s

So, the final velocity of the electron when it reaches point B is 6.45\times 10^5\ m/s. Hence, this is the required solution.

Why is it important for the path of a circuit to be circular?
vredina [299]

Answer:

When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.
