Answer:
The SR-71 Blackbird.
Explanation:
The Lockheed SR-71 "Blackbird" was an American strategic reconnaissance aircraft that traveled at over mach 3, or 3 times the speed of sound. The Concorde was a French passenger jet with a top speed of just over mach 2. The Bell X-1 was the first supersonic test plane and had to be dropped from a larger plane to reach altitude.
Answer:
The weight of a person on the moon is less, compared to their weight on Earth.
Explanation:
Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.
Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.
EXTRA
The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.
Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.
You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.
Answer:
Passive transport.
Explanation:
The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.
Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.
Thus, the correct answer is option (c).
