As we know that as per Newton's II law we have
here we will have
= change in momentum
= time interval in which momentum is changed
now in order to have least injury during jumping we need to have least force on the jumper
so in order to have least force we can say that the momentum must have to change in maximum time so that amount of force must be least
So we need to increase the time in which momentum of the system is changed
The answer is D. Variable. Hope this Helps:)))
Answer:
Stretch and moving away from us, with more distant ones moving faster
Explanation:
Astronomers observed that the entire universe is getting bigger because distant galaxies appears to be moving away from us
The divisions within an atom's shell are called subshells. This means that each shell consists of several subshells that are made up of orbitals. Each orbital consists of 1 or 2 electrons. The outermost shell of an atom is what we call the valence electrons, and they are what participate in chemical bonding.
Answer:
Acceleration
Explanation:
The advertisement is describing the acceleration of the car.
Acceleration is the rate of change of velocity per unit of time. It can be expressed mathematically as;
Acceleration = 
v is the final velocity
u is the initial velocity
t is the time taken
Any quantity that specifies the rate of change of velocity of a body within a given time frame is describing its acceleration.
