Ayudenme con esto porfavor es para un examen! Se muestra un objeto sumergido en agua y en reposo. Considerando que la densidad del objeto es 0,750 g/cm3, Determine: a) La masa del objeto, considerando el volumen del cuerpo igual a 700 cm3. b) La magnitud de la fuerza de empuje sobre el objeto, usando el resultado de la parte A.(g=9,81m/s2) c) El volumen sumergido del objeto.

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

2. -/1 pointsserpse10 2.7.p.017.mi. an object moving with uniform acceleration has a velocity of 14.0 cm/s in the positive x direction when its x coordinate is 2.97 cm. if its x coordinate 2.85 s later is -5.00 cm, what is its acceleration? cm/s2 need ? read it master it

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
