Answer:There's an increase in it potential energy
Explanation:there is an increase in it potential energy
No, only average speed can be calculated from the distance of 90 meters and the time 3 seconds hope this helps
1.39m/s
Explanation:
Given parameters:
Mass of car M₁ = 1000kg
Velocity V₁ = 2.5m/s
Mass of second car M₂ = 1800kg
Unknown:
Velocity of second car V₂ = ?
Solution:
For the other body to come to rest, the momentum of the colliding cars must be equal and in the opposite direction:
Momentum of car 1 - momentum of car 2 = 0
Momentum of car 1 = Momentum of car 2
M₁V₁ = M₂V₂
The unknown is V₂
1000x2.5 = 1800V₂
V₂ =
= 1.39m/s

Answer:5 units
Explanation:
Given
magnitude of vector A ![|\vec{A}|=6 units](https://tex.z-dn.net/?f=%7C%5Cvec%7BA%7D%7C%3D6%20units)
magnitude of vector B ![|\vec{B}|=1 unit](https://tex.z-dn.net/?f=%7C%5Cvec%7BB%7D%7C%3D1%20unit)
Smallest value of vector addition can be obtained when they are at angle of ![180^{\circ}](https://tex.z-dn.net/?f=180%5E%7B%5Ccirc%7D)
i.e. ![\vec{A}+\vec{B}=\vec{R}](https://tex.z-dn.net/?f=%5Cvec%7BA%7D%2B%5Cvec%7BB%7D%3D%5Cvec%7BR%7D)
where R is resultant vector
![|\vec{R}|=6-1=5\ units](https://tex.z-dn.net/?f=%7C%5Cvec%7BR%7D%7C%3D6-1%3D5%5C%20units)
when two vectors are
apart then they Produce minimum magnitude vector

Explanation:
sunspots are areas that appear dark on the sun's surface.They appear dark because they are colder that parts of the sun's surface. However, the temperature of a sunspot is still very high. This can cause a sudden burst of energy space. If a solar flare is very intense, the radiation it releases can interfere with our radio communication here on earth
