An airplane passenger has 100 cm3 of air in his stomach just before the plane takes off from a sea level airport. What volume (in cm3) will the air have at cruising altitude if cabin pressure is 7.50 ✕ 104 N/m2 , assuming that the temperature does not change?

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction
