Rocket-powered sleds are been used to test the responses of humans to acceleration. Starting from rest, one sled can reach a spe

ed of 495 m/s in 1.78 s and can be brought to a stop again in 2.16 s.
Find the acceleration of the sled while accelerating.
Please be very thorough in your answer, I have a very hard time understanding if you don't.
Also, find the acceleration of the sled when braking.

Calcula la fuerza magnética de una carga que se desplaza hacia la derecha con una velocidad de 5 X 10 a la 6 metros sobre segund
Diano4ka-milaya [45]

Answer:

La fuerza magnética del electrón es 6.41x10⁻¹³ N.

Explanation:

Podemos encontrar la fuerza magnética (F) usando la ley de Lorentz:

F = qv\times B

En donde:

q: es la carga del electrón = 1.602x10⁻¹⁹ C

v: es la velocidad del electrón = 5x10⁶ m/s

B: es el campo magnético = 0.8 T

F = qv\times B = 1.602 \cdot 10^{-19} C*5\cdot 10^{6} m/s*0.8 T = 6.41 \cdot 10^{-13} N                                

Por lo tanto, la fuerza magnética del electrón es 6.41x10⁻¹³ N.

Espero que te sea de utilidad!

Calculate the work WC done by the gas during the isothermal expansion. Express WC in terms of p0, V0, and Rv.
mote1985 [20]

Complete Question

The complete question is shown on the first and second uploaded image

Answer:

The expression is  W_c =  P_o V_o ln (R_v)  

Explanation:

Generally smallest workdone done by  a gas is mathematically represented as

          dW  =  PdV

Generally for an isothermal process

    PV  =  nRT = constant

=>   P = \frac{nRT}{V}

Generally the total workdone is mathematically represented as

   W_c =  \int\limits^{v_f}_{V_o} {\frac{nRT}{V} } \, dV

=> W_c = nRT  \int\limits^{V_f}_{V_o} {\frac{1}{V} } \, dV

=>  nRT [lnV]   | \left \ {V_f}} \atop {V_o}} \right.

=>  W_c = nRT [ln(V_f) - ln(V_o)]

=>  W_c = nRT ln \frac{V_f}{V_o}

From the question \frac{V_f}{V_o }  =  R_v

=> W_c =  P Vln (R_v)

at initial  state

W_c =  P_o V_o ln (R_v)
