Answer:
B
Explanation:
momentum = mass (kg) x velocity (m/s²)
Answer:
Final momentum after a head on collision is -2kgm/
Explanation:
One ball moves to the right and the other moves opposite and momentum is a vector quantity so that considering the direction
Initial momenta are P₁=2x3=6kgm/s P₂=4x(-2)=-8kgm/s
Final momentum is the vector sum of P(final)= 6-8= -2 kgm/s
Answer:
Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Scientific methodology includes the following: ... Evidence. Experiment and/or observation as benchmarks for testing hypotheses.
Answer:
it should be Work = F * d * cos(theta)
Explanation:
Force is mass * acceleration, and displacement is the distance between the starting and ending point.
we need theta because it can be used to calculate work when going up an incline surface. And we tend to use cosine because we are assuming that our motion is primarily in the X direction.
Answer:
It Depends Cat is indoor or outdoor But As per the body part concern that i will Considered around the neck but Temperature Remain the same which i Analyzed too
Explanation:
A cat's normal body temperature can range from 100.5 to 102.5 degrees. Because 101.5 degrees is right in the middle, it's often referred to as a “normal” body temperature. Being that their body temperature is higher than ours, they can also tolerate higher temperatures (provided they have access to water).
