P = W/t

W = ΔPE = ΔKE

\tt P=\dfrac{\Delta KE}{t}\rightarrow v_1=0,KE_1=0\\\\P=\dfrac{KE_2-KE_1}{t}\\\\P=\dfrac{\frac{1}{2}\times 2500\times 10^2-0 }{5}=2.5\times 10^4~watt

Como se da la transferencia de energia entre los objetos?
tensa zangetsu [6.8K]
El calor es la transferencia de energía de un objeto más cálido a un objeto más fresco. El calor puede transferirse de tres maneras: por conducción, por convección y por radiación. La conducción es la transferencia de energía de una molécula a otra por contacto directo.

If the voltage across a circuit of constant resistance is doubled, the power dissipated by that circuit will
densk [106]

Answer:

The voltage will quadruple

Explanation:

The power dissipated in a circuit is given by

P=\frac{V^2}{R}

where

V is the voltage

R is the resistance

In this problem, the voltage across the circuit is doubled:

V' = 2V

So the new power dissipated is

P'=\frac{V'^2}{R}=\frac{(2V)^2}{R}=4\frac{V^2}{R}=4 P

so, the power dissipated will quadruple.

What is Archimedes principal ?​
Gnoma [55]

The Archimedes principle is a principle that is expressed as a law that states that a body immersed in a fluid, whether fully or partially, is subject to an upward force of the same magnitude as the weight of the fluid it displaces.

What is the magnitude of the sum of the two vectors A = 36 units at 53 degrees, and B =47 units at 157 degrees.
Thepotemich [5.8K]

Answer:

51.82

Explanation:

First of all, let's convert both vectors to cartesian coordinates:

Va = 36 < 53° = (36*cos(53), 36*sin(53))

Va = (21.67, 28.75)

Vb = 47 < 157° = (47*cos(157), 47*sin(157))

Vb = (-43.26, 18.36)

The sum of both vectors will be:

Va+Vb = (-21.59, 47.11)   Now we will calculate the module of this vector:

|Va+Vb| = \sqrt{(-21.59)^2+(47.11)^2}=51.82
