Calculate the kinetic energy of a 5.0kg object moving at 4.0 m/s

Physics
1 answer:
Nana76 [90]3 years ago
3 0

Answer:

The answer is

<h2>40 J</h2>

Explanation:

The kinetic energy of an object given it's mass and velocity can be found by using the formula

KE =  \frac{1}{2} m {v}^{2}

where

m is the mass

v is the velocity

From the question

m = 5 kg

v = 4 m/s

The kinetic energy is

KE =  \frac{1}{2}  \times 5 \times  {4}^{2}  \\  =  \frac{1}{2}  \times 5 \times 16 \\  = 5 \times 8

We have the final answer as

<h3>40 J</h3>

Hope this helps you

What are some ways to separate a mixture?
stiks02 [169]

la separación mecánica de un sólido de grano grueso, insoluble, en un líquido; consiste en verter cuidadosamente el líquido, después de que se ha sedimentado el sólido.  Por este proceso se separan dos líquidos miscibles, de diferente densidad, por ejemplola separación de un sólido disuelto en un líquido, por calentamiento, hasta que hierve y se transforma en vapor. Como no todas las sustancias se evaporan con la misma rapidez, el sólido disuelto se obtiene en forma pura, agua y aceite.

A rectangular loop consists of 80 turns, each carrying a current 8
liberstina [14]

Magnetic moment of loop is given by the formula

M = NiA

M = 80*8 *0.4*0.3

M = 76.8

now magnetic field is given here

B = 40 * 10^{-3} T

Now the torque on the loop is given by

T = MBsin\theta

T = 76.8* 40*10^{-3}*sin30

T = 1.536 Nm

so above is the torque on the loop.
