1. If you were to visit a planet that was much more massive than earth, your mass would be a) More b) Less c) The same d) Impossible to tell without knowing which planet you are visiting. 2. Which of the following is not a form of light? a) radio waves b) microwaves c) x-rays d) All of the above are a form of light. e) None of the above is a form of light

A box sitting on a horizontal surface is attached to a second box sitting on an inclined ramp by a rope that passes over an ideal pulley. The rope exerts a tension force T on both weights along the direction of the rope, and the coefficient of friction between the surface and boxes is 0.4 . If the box on the right weighs 100 pounds and the angle of the ramp is \( 36^{\circ} \), how much must the box on the left weigh for the system to be in static equilibrium? The box on the left must weigh approximately (Do not round until the final answer. Then round to two decimal places as needed.)

- Cuál es el área mínima de un bloque de hielo flatando en el ugua para poder sustentar a un aulomóvil que pesa 1200 kg f?. El bloque tiene una altura de \( 2 \mathrm{~mm} .\left(\rho_{\text {hielo }}=0,9 \mathrm{gf} / \mathrm{cm}^{3}\right) \).

Dados los vectores: \( \vec{u}=3 i-j+7 k \) \( \vec{v}=4 i+5 k \) \( \vec{w}=-5 i+2 j-k \) El producto \( (\vec{v} \cdot \vec{w}) \) multiplicado por el vector \( \vec{u} \) está representado por:

A box sitting on a horizontal surface is attached to a second box sitting on an inclined ramp by a rope that passes over an ideal pulley. The rope exerts a tension force I on both weights along the direction of the rope, and the coefficient of friction between the surface and boxes is 0.6 . If the box on the right weighs 100 pounds and the angle of the ramp is \( 35^{\circ} \), how much must the box on the left weigh for the system to be in static equilibrium? The box on the left must weigh approximately \( \square \) pounds for the system to be in static equilibrium. (Do not round until the final answer. Then round to two decimal places as needed.)
