B.
This equation quantifies the inter convertibility of mass and energy and helps us understand the large amount of energy that would be released if mass were converted to energy.<span />
Answer:
608.4m/s
Explanation:
We are given that
Mass of Sleigh,M=1200 kg
Speed of Sleigh,u=322 m/s
Speed of jet,u'=680 m/s
Mass of jet,m=4800 kg
Total mass=M+m=1200+4800=6000 kg
We have to find the final velocity of the two objects after the collision.
The collision is inelastic .
By using law of conservation of momentum
Using the formula
Hence, the final velocity of two objects after the collision=608.4m/s
Reduce speed or slow down.
Orange signs and cones are usually present when a path is diverted or is not entirely available for cars to drive on. The diversion may be due to hazards present due to the construction or for the safety for the construction workers. One must slow down when passing through such construction zones in order to prevent collisions and injuries.
Explanation:
Carbon-14 is normally used to date living organisms (all living things we know today contain mostly carbon). It can be used for samples up to about 60000 years old. Carbon-12 is the non-radioactive form that we encounter daily. Relative dating determines dates relative to each other, such as ordering of period or events.
Uranium 235 dating can determine date samples a million years old and up, so is more suited for rocks.
