Answer: are breathing much faster
Explanation:
Exercise is a physical activity which increases the rate of respiratory and cardiovascular activity of the body. The cardiovascular exercise is likely to increase the rate at which the heart pumps blood as the body faces the scarcity of oxygen in the muscles which conducts the exercise. This increases rate of breathing so as to acquire more amount of oxygen. The oxygenated blood is pumped by the heart to all the parts of the body.
1 velocity.
2 speed.
3 acceleration.
4 direction.
Answer : speed
Explanation :
Speed is defined as the distance travelled per unit time. It is a scalar quantity.
Velocity is displacement covered per unit time. It is a vector quantity. This means it have both magnitude as well as direction.
When captain told the passengers that the plane is flying at 450 miles per hour, then this shows the speed of plane. He is not talking about the direction in which the plane is flying.
So, this information describes the speed of plane.
Correct option is (2).
walk on the moon
orbit the earth
do a spacewalk
Answer: orbit the earth
Explanation:
In 1962, with three orbits around the Earth, John Glenn is the first American Astronaut to do so.
John Glen was selected in NASA in 1959. He flew Friendship 7 mission on 20th February, 1962. He was the first American to orbit the Earth. He took three rounds about the Earth.
propulsion is an example of which Newton's Law?
A. 1st Law
B. 2nd Law
C. 3rd Law
D. All of Newton's Laws
Squids and octopuses forcefully expel water through the siphon after ingesting it, propelling themselves through the water. Third Law of Newton.
His third law asserts that there is an opposite and an equal response in nature for every action (force). When an object A pulls on an object B, the opposite force is applied to the first object by object B. Alternatively said, interactions lead to forces.
There are numerous real-world applications of Newton's third motion law. For instance, when you leap, the earth exerts an equal and opposing reaction force that propels you into to the air. This is because when you apply a force to it with your legs, it responds in kind. Rockets and other projectiles are designed using Newton's third law by engineers.

Answer:
BP supreme-grade gasoline,then for all BP grades of gasoline, and then for all gasoline.
Explanation:
Demand will always more elastic for luxury good. Here, BP supreme-grade gasoline is considered as a luxury product. Then comes BP grades gasoline, which is less elastic than the previous one.
