Answer:
The position of my house is a little uphill as compared to the position of my school. The distance I have to travel from my house to school is nearly 2 kilometers. The displacement is in the 2000 m towards the left from my house. The speed of the bus which I usually take is 40 km/ hour.
The moon<span> is 1/4 the size of </span>Earth<span>, so the </span>moon's<span> gravity is much less than the </span>earth's gravity, 83.3% (or 5/6) less to be exact. Finally, "weight<span>" is a measure of the gravitational pull between two objects. So of course you would </span>weigh<span> much less on the </span>moon<span>.</span>
Answer:
1. P⃗ A,i+P⃗ B,i=P⃗ A,f+P⃗ B,f
Explanation:
Collision occurs when two bodies moving at different velocities exert force on each other through colliding. Collision can either be elastic or inelastic.
For elastic collision, both energy and momentum of the bodies is conserved i.e they separates after collision.
For inelastic collision, only momentum is conserved but not energy. The body sticks together after colliding and moves with a common velocity.
According law of conservation of momentum which states that the sum or momentum of two bodies before collision is equal to the momentum of the bodies after collision.
Given two bumper cars A and B that undergoes collision during which momentum is conserved, the type of collision that exists between the bumpers is inelastic collision
.
If initial momentum of A is PiA and initial momentum of B is PiB, the sum of their momentum before collision is expressed as;
PiA + PiB ... (1)
If final momentum of A is PfA and initial momentum of B is PfB, the sum of their momentum after collision is expressed as;
PfA+PfB ... (2)
According to the law, equation 1 is equal to equation 2
The fore the formula that states the law is expressed as;
PiA + PiB = PfA+PfB
Answer:
An amorphous solid does not have a definite melting point; instead, it melts gradually over a range of temperatures, because the bonds do not break all at once. This means an amorphous solid will melt into a soft, malleable state (think candle wax or molten glass) before turning completely into a liquid.
Explanation:
Hope this helps
May I get braineist pls?
Speed is a scalar quantity that refers to “how fast an object is moving.”
