Answer:

kinetic \: energy =  \frac{1}{2}  \times m {v}^{2}

Answer:

54 Joules

Explanation:

recall that kinetic energy is governed by the equation:

K.E = (1/2) mv²

where,

m = mass = given as 3 kg

v = velocity = given as 6 m/s

Substituting these known values into the above equation,

K.E = (1/2) mv²

K.E = (1/2) (3)(6)²

K.E = 54 Joules

andrew-mc [135]
<h2>Answer:</h2>

<em>Hello, </em>

<h3><u>QUESTION)</u></h3>

Assuming that the initial velocity of the jumper is zero, on Earth any freely falling object has an acceleration of 9.8 m/s².  

<em>✔ We have : a = v/Δt = ⇔ Δt = v/a </em>

  • Δt = (√2xgxh)/9,8
  • Δt = (14√10)/9,8
  • Δt ≈ 4,5 s

Does magnets exert a force. explain​
Ratling [72]

Answer:

Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Hope this helps you! :)

Which among the following statement/s is correct?
seropon [69]

Answer:

(D) None

Explanation:

The force of gravity is the force pulling every element of matter together. The more the matter the higher the force of gravity.

Examples of this force at work are;

  • The force that causes an apple to fall from the tree
  • The force that causes a rock to roll downside a hill
  • The force causing people to walk on the earth surface instead of floating

The force that facilitates a pen on your hand to write on a paper is friction force between the pen and the paper. Gravitational force acts downwards thus force applied on an object beside you is not the force of gravity.

nekit [7.7K]

the magnitude of charge=q=8.76 x 10⁻⁵C

Explanation:

the magnetic force Fm is given by

Fm= q V B sinθ

q= charge

v= velocity= 2.5 x 10⁴ m/s

B= magnetic field strength= 8.1 x 10⁻²T

Fm= magnetic force= 7.5 x 10⁻² N

θ=25°

so 7.5 x 10⁻² =q (2.5 x 10⁴ ) (8.1 x 10⁻²) sin25

q=8.76 x 10⁻⁵C
