On December 7th, 1941, Pearl Harbor was attacked by Japanese forces. The next day, Franklin D. Roosevelt addressed the United States Congress with his memorable “a date which will live in infamy” speech.This speech had two purposes:To rally the American people to support the war effort.
Answer:
No, it will not affect the results.
Explanation:
For elastic collisions in an isolated system, when a collision occurs, it means that the systems objects total momentum will be conserved under the condition that there will be no net external forces that act upon the objects.
What that means is that if the pucks start spinning after the collision, we are not told that there was any net external force acting on the puck and thus momentum will be conserved because momentum before collision will be equal to the momentum after the collision.
The orbit of a space shuttle is surprisingly like an apple falling from a tree to earth. The space shuttle is simply moving so fast that the path of its fall is an orbit around our planet. Which of Newton’s laws helps explain the orbit of a space shuttle around earth and the orbit of earth around the sun
Jupiter and saturn have hydrogen + helium. mars, like venus, their atmosphere have co2 + nitrogen
Answer:
Explanation:
a)
Apply the law of conservation of momentum
Since there is no external force(friction) oon the system, Momentum in horizontal direction must remain constant.
Initial Momentum = Final Momentum
b)
Apply law of conservation of energy
Loss in Potential Energy = Gain in Kinetic Energy
